How to connect to the Internet via fiber optic. Choosing a WiFi router for fiber optics

When laying optical communications It is simply impossible to do without connections, since when installing the main line there is not always enough cable length, and when arranging a regional or intra-house network, it becomes necessary to branch one large cable into several small ones.

Today, three methods of connecting fiber optics are widely used:

mechanical method;
connection using splice;

The mechanical method of connecting an optical fiber is an ambiguous concept and does not mean at all that the entire procedure is carried out without the participation of high-precision equipment. In this case, there is no way to do without welding work. And this method is performed in the following way:

a mechanical fiber optic connector (pigtail), which is a small piece of optical fiber with a factory-installed connector, is welded to the cable using an automatic welding machine;
Next, you need to connect the welded extension to equipment equipped with the necessary connector for this.

This connection method requires constant maintenance, as the connectors periodically become dirty and need to be cleaned. It is also worth noting that the level of signal loss is very high, which is completely unacceptable when laying external highways.

Connection using splice. A truly manual method of splicing prepared fiber optic cable ends that requires highly qualified of a master performing the work, minimum the necessary tool produced without welding. The entire installation process is much easier and faster. And it is done as follows:

two ends of the optical fiber are processed according to standards;
after that, through special guides, they are brought together in the direction of each other in the splice itself and fixed;
Next, the process of restoring the protective sheath and armor of the cable follows.

To minimize signal loss, the splice cavity is filled with a special gel (often it is already in the connector). Compared with mechanically, connecting an optical fiber using a splice shows less attenuation in the optical cable. However, often this coefficient can be equal to 0.1 dB. At the same time, it is also worth paying attention Special attention the fact that the level of losses in this type of connection may increase over time, which will require additional adjustments to the position of the spliced ends in relation to each other. This is caused by displacement of the cable during operation or drying out of the gel.

The third and most reliable way to connect a fiber optic cable is welding. This option for splicing ends is the most durable. Even with a longer process, unlike a mechanical fiber connector or splice, it shows excellent results in minimizing signal level losses to 0.04 dB, which has a positive effect on signal quality. The process itself involves the sequential execution of a number of operations related to the preparation and direct splicing of the ends of the optical fiber and is worthy of a separate article.

Optical cables are the most attractive means of transmitting large amounts of information. However, we should not forget that extending optical fiber to one computer is an almost never used practice.

Details about connecting optical cables can be found at http://www.optcable.ru/kabel-no-provodnikovaya-produkciya/opticheskij-kabel/. This publication will present general techniques.

Difficulties in connecting the optical wire

Needless to say, an optical wire is nothing more than a core made of transparent plastic or glass. Naturally, it is not possible to connect such a wire by twisting.

Specialized equipment is used to solder the optical conductor. There is no point in renting it (only if, in principle, there are no specialists in the area who can install optical fiber).

It is extremely important to ensure high-quality preparation of conductors for soldering. It is performed as follows:

First, the ends of the optical fiber are broken off at an angle of 90 degrees;
the ends of the optical fiber are soldered at right angles;
at high temperature in a special environment, the optical fiber is soldered;
a protective insulating layer is installed.

However, the optical cable cannot be connected directly to the computer. And this is not required at all.

Today, specialists use Ethernet converters.

In many ways, the difficulties of connecting fiber optics are due to the choice of a suitable converter. Next, the already familiar twisted pair cable comes out of the said equipment, which is connected to the computer via Ethernet.

Why have optical cables become so popular?

The fact is that the volume of information is increasing exponentially. The exponential need to transmit increasing volumes of information forces specialized organizations to use reliable data transmission channels.

It is not possible to transmit such data arrays electrically.

In addition, transmission would be similarly affected by electromagnetic interference. The percentage of information lost when broadcast over long distances is unacceptable.

Among the disadvantages of optical fiber is the impossibility of folding it at an acute angle due to the risk of breaking.

How to connect an optical cable? | Want to know everything!

A digital optical audio cable is required when transferring a compressed digital audio signal from a computer (CD player) to speaker system or the receiver. If necessary, you can connect it yourself.

This cable does not require the use of electricity when transmitting a digital signal, does not create interference, and almost does not distort the sound on the computer. Install all drivers and application software that comes with the sound or motherboard in strict accordance with the instructions. These actions will enable the computer and external audio signal receiver to correctly determine optical connection for the period of connection.

This procedure is not required for household audio devices that are specifically designed to operate using an optical cable. These include a digital home theater equipped with a built-in electronic circuit that can independently determine the signal connection period using an optical audio cable.

Next, you should connect one end of the audio cable to the source port on an external sound card (computer) using an S/PDIF connector. This is a rectangular port that is compatible with audio cable connectors that are tamperproof.

The other end of the cable connects to the digital audio receiver port. Most often on consumer audio devices they are designated TOSLINK, Optical Digital, S/PDIF. Other audio cables and connecting devices should be disconnected as the audio system may continue to use them by default. You can use the input selector on the amplifier.

How to properly connect speakers to a TV: 3 ways

Connecting speakers to a TV is quite simple. Just a few years ago, we could hear high-quality and surround sound in cinemas or at concerts. In private, stereos and powerful tape recorders were used. They were loud, of course, but the sound came from two speakers. Nowadays, you can enjoy excellent sound and picture using home theaters equipped with various sound systems, which in turn need to be connected and configured correctly and with understanding.

In order to connect all the speakers to your home theater, you don’t need to be a pro in this matter. Just follow these instructions. A properly connected sound system will delight you with surround and high-quality sound.

To connect you will need:

Receiver;
Columns;
Cables for connection.

No matter what system you have, the first point of connection will be sound. A standard set of various sound systems is the presence of several speakers (front, rear, center) and a subwoofer. The methods for attaching the wires to the contacts vary, but their connection diagram is the same for all.

Front speakers, since they are the main sources of sound, are usually placed close to or near the TV, and their backs are directed towards the wall. The sockets on the receiver for connecting front speakers are marked (Front).

You can connect the speakers to the TV using the instructions

The cable for these speakers is divided at the ends into two multi-colored wires (usually black and red), where red is positive and black is negative. They are connected either to clamping or threaded contact connections.

If after connection there is no sound from the speakers, then the positive and negative contacts are reversed.

The central speaker (if there is one) is also responsible for the main sound. It is located directly next to the TV. The height of the location depends on your taste. It is connected to the home theater in the same way as the front one and is marked on the receiver body (Center).

Next, the rear speakers are connected in the same way. They are placed opposite the front ones, thereby achieving unique surround sound. Marked (Surround). And then a subwoofer is connected, which saturates the sound with low frequencies. Labeled (Subwoofer).

How to connect a home theater to a TV: instructions

The way a home theater works is that the processed signal from the source is sent through the receiver to the speakers and to the TV screen. To transmit images through a home theater, there are several connection methods.

Connection types:

HDMI cable;
RGB cable;
Composite connector.

In order to display a high-quality picture on the TV screen, use the method using an HDMI cable, which usually comes with cables for connecting a home theater. It is simply not possible to confuse the correct connection, which makes the task easier. The cable plugs resemble the charging plug (USB), only slightly bigger size. To connect, find the inscription (HDMI OUT) on the receiver, and (HDMI IN) on the TV.

Connecting your home theater to your TV

The peculiarity of the HDMI cable is that it is capable of transmitting not only a picture, but also sound.

It may be that your TV is missing a connector or is already occupied by another cable. In this case, you can use an RGB cable. Unlike the previous one, this cable is capable of transmitting only images. This cable consists of three wires connected together with tips of three colors (red, green, blue). It is connected to the connectors marked (Component Video Out) and (Component In), according to the colors of the connectors.

It is also possible to connect using a composite cable. Connection is made through composite connectors marked (Composite Video Out) and (Composite In). Unlike other connection methods, this one displays a picture of not very high quality.

Methods: how to connect a laptop or computer to a home theater

Currently, everything more people The TV is used as “furniture”. With the development of Internet technology, it became possible to listen to music and watch movies on a computer. And to enjoy high quality picture and sound, you can connect your computer to your home theater.

Connection methods:

Using cables;
Via an external sound card.

To ensure the transfer of surround sound from a laptop to a home theater, you need an HDMI cable. It makes it possible to transmit both picture and sound. To do this, you need to connect the cable connector to the GDMI output on the laptop, and the second directly to the cinema (receiver). After this, the sound and picture should be reproduced through the cinema.

If this does not happen, you should configure the playback device on the computer itself. To do this, go to the control panel and select the Sound tab. Next, the playback tab opens. Select a device that supports HDMI, right-click on it and select “use default device.” Then click on “settings” and select the appropriate system for playback (5.1 or 7.1). The setup is complete and the sound should disappear from the laptop speakers.

If the connection is made through a computer video card with a DVI to HDMI adapter, then the sound will need to be supplied to the receiver manually. To do this, use an SPDIF cable to connect motherboard or sound adapter with video card.

You can connect your home theater to your computer using a cable

It is important to know! The integrity of the cable directly depends on the correct connection. The cords must be connected according to the markings.

If your laptop does not have an HDMI connector, you can use simple solution in the form of an external sound card. To connect it, no special skills or knowledge are required, as well as some types of special installation programs. These devices allow you to connect not only receivers, but also microphones and headphones.

You can also use your phone to control the system.

Optical cable intended for TV or home theater

Modern technologies, allow the use of optical cables not only for industry; quite often they are used for high-speed and high-quality transmission of various kinds of signals. They have also found application for connecting televisions and home theaters.

The optical cable is intended:

Internet connection;
Transmission of sound and image.

Using optical cables, you can connect 5.1 sound systems to the TV, as well as the Internet. Important condition when connecting various systems, is correct selection cable, which will allow reliable connection and long-term work.

Optical cable must be chosen wisely

A TOSLINK cable is a common cable for connecting audio systems, as it supports many formats. But to transmit video to TV screens, cables with markings (EIAJ / JEITA RC-5720) are used. TOSLINK cables are used by such well-known manufacturing companies as LG (LG), Samsung (Samsung) and Genius.

But they have some disadvantages. These cables may transmit noise, cause picture jitter, or interrupt communication. These models have high resistance.

It is important to know! To transmit the highest quality image and sound, it is recommended to use cables no longer than 4 meters long.

But the main difference from other types is that fiber optic cables have a very high throughput. And their correct use will allow you to achieve good results.

How to connect sound and TV (video)

As you can see, connecting various audio systems and home theaters, as well as their individual parts, does not require specialized knowledge and skills. You can easily handle this yourself. And don’t forget that when purchasing a home theater, it always comes with detailed instructions.

A digital optical audio cable is used to carry a compressed digital audio signal from a source (computer or CD player) to a receiver or speaker system. Optical audio cable is good for short distances where there is a high risk of radio frequency interference (interference). Such a cable does not use electricity to transmit a digital signal from a source to a receiver, so it is not a source of interference in itself, produces less distortion of sound on a computer, and also allows for galvanic isolation of electronic devices.

Typically, an audio cable using optical fiber uses the S/PDIF audio interface format, which in its full name means Sony/Phillips Digital Interconnect Format. There is another version of this interface based on a coaxial cable. It is worth noting here that the optical interface is very convenient for transmitting multi-channel sound over one speaker cable, which is impossible with other classic types of connection. This is facilitated by the use of multimode optical fiber.

Instructions

1. Install all drivers and applications software, which came with the sound or motherboard, in accordance with the manufacturer's instructions. This will allow the computer and external audio receiver to correctly identify the optical connection at the time of connection. This step won't have to be performed on consumer audio devices that are specifically designed to operate over an optical cable. For example, a digital home theater has a built-in electronic circuit that independently determines when a signal is connected via an optical audio cable.

2. Connect one end of the fiber optic audio cable to the source port (on your computer or external sound card) via an S/PDIF connector. This connector is a rectangular port that is compatible with the audio cable connector and is tamperproof.

3. Connect the other end of the optical cable to a digital audio receiver port, such as a receiver. Typically on consumer audio devices this port is designated as “S/PDIF”, “Optical Digital” or “TOSLINK”.

4. Disconnect all other audio cables connecting devices (coaxial cables) as the audio system may continue to use them by default. Or use the input selector on your amplifier. We advise you to read interesting article on how to turn on sound in safe mode.

To connect optical cables in couplings or install pigtails in cross-connects, a welding machine is usually used - it allows you to securely fix the fibers with maximum density, as well as leave technological reserves for reconnection and movement of fibers in the cable under the influence of temperature and tensile force. In most cases, welding is the most convenient type of connection. But it also has disadvantages that can be solved by installing fast connectors on the cable.

What problems arise when using welding as the main type of connection?

1. The spot where the optical fiber is welded becomes brittle and should be fixed with a special heat-shrinkable sleeve KZDS.

2. The heat-shrinkable sleeve requires fixation, because does not protect the fiber from tensile stress.

3. The fiber on both sides of the sleeve may break because the protective shell has been removed from it.

4. It is impossible to connect fibers by welding in difficult conditions, for example, when there is no fiber supply or on a pole without a technological fiber supply.

From everything it follows that when terminating a cable, the installation of a small cross-connect is always required, and when deploying networks in the private sector, it is always necessary to remove the coupling from the pole and leave ringlets of the main and client cables, which over time creates a web of wires. And most importantly, such work cannot be carried out by one installer, because... he simply will not be able to remove the clutch.

We insert the optical fiber into the central tube and move the clamping slider to the right, thereby fixing it in the connector. By moving it back, you can remove the fiber from the connector.

It is necessary to leave a supply of fiber under the cover that clamps the cable from slipping. Quick connector typeS.C. It is placed directly on the cable, so you cannot leave a large supply of fiber, as when using a welding machine. If the cable length is more than 200 meters, measures must be taken to prevent the movement of fibers inside the cable, for example, leave a reserve rolled into rings.

Closing the lid fast connector and tighten the clamping sleeve. Although the connector is designed for installation on a FTTH cable, it can also be installed on the central tube of the cable.

ATTENTION!!! When installed on the central tube, it is not securely fixed in the connector; you need to put a piece of this tube on top, or wrap a little electrical tape to increase its thickness. In this case, the fastening will be reliable.

All that remains is to put the blue plastic clip on the socket and you're done - the fiber can be connected to the equipment. You can connect it directly or place it in a cross or wall socket, and connect the equipment through an intermediate patch cord.

Now, for comparison, we will install the connector using an optical welding machine. The connectors themselves are not directly installed on the cable by welding, so you need to use a cut patch cord or a special optical pigtail. It is welded to the cable fiber and installed in the cross-connect.

Exist optical patch cords with connectorsS.C. different lengths, they usually have a thick insulation of 2 or 3 millimeters, there are also special pigtails (cut patch cords), with a thin outer insulation of 0.9 millimeters. You can use any, but for tight installation of a multi-fiber cable in a cross-connect, it is more advisable to use pigtails with thin insulation - they are easy to bend and fix, and do not take up much space.

You can make a pigtail from a patchcord using a special cable stripper with different hole diameters. Cut it in half and remove the top protective insulation.

As a result, we get the same optical pigtail, which, when compared with optical fiber, has a slightly thicker protective shell.

We cleave the optical fiber from the cable along a 20 mm ruler with a cleaver JilongKL-21 C. Naturally, the fiber must first be cleaned and the buffer coating removed with a stripper.

We clamp the fiber with the clamping bar of the cleaver KL-21 C, close the lid and chip.

We perform a similar operation with a welded patch cord - remove the buffer coating, wipe it and chip it.

Turn on the welding machine JilongKL-280G and wait for it to be ready for work when the corresponding message appears on the screen.

Open the protective cover of the welding machine and place the pigtail on the right clamping pad, the fiber should fall into the V-shaped groove in front of the welding electrodes. First, you need to put a KZDS heat-shrink sleeve on the fiber.

Similarly, we lay the fiber from the optical cable on the left. Router MikrotikRB450G We use it as a cable stand.

After closing the lid of the welding machine JilongKL-280 it automatically combines and welds the fibers, but first checks the quality of the cleavage produced. The device did not like the chip, so it issued a message that the chip angle was exceeded. Although the defect in the fiber on the right is visible on the screen of the device, it is not always clearly visible and it would not be bad if the device reported which side the bad chip was on.

The error message from the welding machine screen is “The chipping angle has been exceeded.” He suggests ignoring the defect and continuing, but it is better not to do this and re-chip the fiber.

After repeated actions of chipping, cleaning and laying the fiber, the device welded without any problems and showed information about losses in the welded joint - Loss: 0.01dB- this value must be shown for all welds, if it is higher 0.03 , then you need to reconnect the fibers.

Introduce fibers into the apparatus JilongKL-280G it is possible even in a protective shell; a special gasket under the cover and the corresponding cutout allow this.

After welding, the fiber is stretched between the clamping bars; if you move one with your finger, the second will also move, so you should open the covers carefully.

The result is such a beautiful connection, but the eye of a specialist will immediately understand that something is wrong.

They forgot to put on the KZDS heat-shrink sleeve, and without it the fiber can easily be broken. This is one of the main mistakes when starting to work with optics. You will have to cut the fiber and re-weld it. You can’t just take and cut the fiber anywhere, you need to find the welding point and cut it on both sides, like a red ribbon when builders open new facilities.

We re-cleave with a cleaver JilongKL-21 C, just put the ruler at the very minimum value so that the buffer coating is on the maximum possible length of the optical fiber.

We put on a heat-shrink sleeve and reintroduce the fibers into the welding machine.

We carry out welding and get the result - Loss:0.36dB- this is a lot, you need to cut and re-weld. It can be seen that the fiber was welded with an offset, which indicates that it is impossible to place fiber with the buffer coating not removed into the groove of the welding machine.

But the KZDS sleeve is in place, but it does not cover the entire fiber with the buffer coating removed - on the cable side the end of the exposed fiber was short, and on the patchcord side they forgot to equalize the length. We cut again.

We try to immediately place the fibers into the welding machine without chopping off their ends - and here is a clear result. It immediately becomes clear why a cleaver is needed and whether it is possible to do without it. Optical fiber splicing machine JilongKL-280G will not work if their ends are not processed.

The device issues a corresponding warning.

Now we make the chip according to all the rules, cutting the fiber according to the ruler by 16 millimeters.

And again we get to a message about exceeding the cleavage angle, look in the picture which fiber has a defect (in in this case right) and make a second chip.

Inserting fibers into the device JilongKL280 G and close the lid. The fibers must move freely, because the device may pull them inward during mixing. Also, you should not place the fibers deeper than the welding electrode, the device will display an error message - it can only pull the fibers into itself, and not push it back.

The welding process is carried out automatically, this is the main difference between the welding machine JilongKL-280G from usual KL-280.

Again, something went wrong and the device reported a welding failure with interesting picture fibers with a hole in the center need to be cut and remade again.

However, the fiber itself with the defect was welded and was quite strong.

We re-weld.

And we get the required level of losses - Loss: 0.01dB.

Carefully take out the fibers, move the KZDS heat-shrinkable sleeve to the welding site and place it in the oven at the top of the welding machine.

We close the lid, but the thick cable sheath interferes with it - no problem, the stove can work with the lid ajar.

To turn on the stove, press the button HEAT on the panel of the welding machine.

And upon completion of the shrinking process, remove the sleeve and place it in a special metal holder to cool completely. The sleeve may stick in the stove, so you should remove it immediately after the sound signal.

Here is the result, the fiber is welded, the KZDS sleeve is on, but it still needs to be handled carefully and needs to be placed in a cross or wall box.

View from the side of the connectors to the connections various types. Up fast connector put on the central tube of the optical cable, at the bottom there is a patch cord welded to the main cable.

On the other hand, everything is not so neat. While the end of a cable with a fast connector can be bent as desired, the end of the cable at the welding site is very easy to damage and needs to be protected by placing it in a small wall-mounted optical box, and you will need to use an additional pigtail to connect active equipment.

Of course, you can cut the fiber so that the central tube of the optical cable goes into the KZDS sleeve, and the buffer coating of the pigtail is also inside, then when shrinking, both the main cable tube and the welded patch cord will be securely connected.

Naturally appearance This type of connection is not very neat. Thick yellow insulation cannot be put into the sleeve, because... it is not clamped by the foot of the welding machine; here you can either wrap everything with electrical tape, or put on several ordinary heat-shrinkable tubes for electrical cables.

Compared to welding connection quick connector with connectorS.C. It is faster and easier; in addition, in some cases the use of an optical cross-connect and unnecessary adapters with patch cords is not required. Which can be convenient when connecting subscriber cables to couplings on poles using quick connectors rather than welding. The fibers are pre-melted in the coupling and sockets are installed, subscriber cables on the ground are terminated with connectors and connected to the coupling, while no extra cable is required and a web of wires does not appear on the poles. In addition, fast connectors can be used in the construction of networks based on PON technology.

The cost of the cheapest optical cable is less than a twisted pair, so a set of a cleaver, stripper and fast connectors pays for itself very quickly, especially if you often have to lay communication lines more than 100 meters long.

IN Lately became of interest to many people fiber optic internet. Most people know that this technology involves quite high speed. Not so long ago, such speeds seemed fantastic to many, although technology began to develop almost a century ago - back in the thirties of the last century. That is why it is worth considering what fiber-optic Internet is and why such technology is beyond competition.

A little history

The first attempts to transmit data over a distance using light and transparent materials were made back in 1934. Norman French proposed converting voices into light signals, which would then be transmitted along glass rods. A few years later, a physicist from Switzerland, Jean Daniel Colladon, conducted an experiment with the transmission of light through a “parabolic liquid flow,” that is, water. Optical fiber in modern form appeared in 1954. The authorship belongs to two physicists from England - Harold Hopkins and Narinder Singh Kapani, as well as a researcher from Holland - Abraham Van Hiel. Since they simultaneously announced their invention, all three of them began to be considered the founders of this technology. And two years later the name was invented - optical fiber.

The light losses of the former were very large. In the late fifties, Lawrence Curtins was able to reduce them. And when laser technology was discovered in 1962, fiber optics had another chance to exist.

Peculiarities

Now we can return to modern times. On this moment Fiber optic Internet is characterized by incredibly high data transfer speeds. This is not at all surprising. The carrier of information in this case is light, and its speed of movement is the highest in the Universe. Such a property had to be used, and it is. In a simplified sense, it is transmitted like this: if the light is on, then it is 1, and if not, then it is 0. A fiber-optic Internet cable transmits alternating zeros and ones at such a speed that it is simply impossible to see with the naked eye. A transmitter that converts electrical signals into light is responsible for changing pulses. And at the second end of the cable there is usually a receiver that performs the inverse conversion.

Fiber optic Internet is characterized by enormous speeds, which is its main advantage. Another advantage is the ability to work over long distances. for the Internet is laid along the bottom of the ocean, it can stretch across the entire continent. Naturally, the installers who lay it have a very difficult time: they install signal amplifiers at the joints, which cost several hundred times more than the wire itself, but for the technology as a whole such investments cannot be called excessively large.

Additional properties

This method is also used in other areas. By means of the finest wiring it is possible to provide illumination during complex operations on the human heart or brain. Light systems are also gaining popularity, based on the same optical fiber, but instead of information they bring into the home sunlight, which is caught from the street.

In addition to the speed and long range of information transmission, such technology has one more advantage - it is almost impossible to intercept information when using it.

Fiber optic Internet: disadvantages

There is only one drawback - the equipment and tools for installation are too expensive. The cable itself is not that expensive compared to transmitters, receivers and signal amplifiers. The soldering of wires is carried out using special inverters, which can cost as much as very expensive cars.

Characteristics

Fiber optic Internet is characterized by high speed, as described earlier. For home use, its minimum is 10 Mb/s. Physically, no home cable is capable of supporting such speeds. It is best to use such a connection if you have a home server, or if you have not one, but several computers that constantly need access to the Internet. To split the fiber optic cable, you need to install a special router. It can be intended for home use or for main channels. Fiber optic Internet will work with special routers that were produced no earlier than 2010. Their model range is quite extensive, so you can choose the best option for each user.

Fiber optic Internet (Rostelecom)

For several years now, Rostelecom has been providing citizens with access to the World Wide Web using ADSL technology, which involves transmitting a signal over a regular telephone line. Now the operator has begun to actively implement completely new methods. Fiber-optic Internet using FTTB technology (fiber to the building) is now being actively implemented. With its help, you can significantly improve the quality of services provided to the population, the reliability of the connection and its maximum speed, which can reach 100 megabits per second. When the network undergoes a complete modernization, every resident of the selected settlement will be able to take advantage of the full range of services. For example, it will be possible to watch digital television, which is many times superior to cable and satellite in quality and capabilities. Such a solution is high quality video, image and sound, as well as a convenient interactive menu, ease of use and other advantages.

conclusions

At the moment, fiber optic Internet is an advanced solution to the problem of data transmission. Only cryptonetworks that are still at the design stage are capable of surpassing it in speed, and it is not yet particularly clear when their development will begin. That is why it is worth thinking about how to connect fiber optic Internet.

According to experts, for the next few years, the most efficient data transmission on the Internet will be provided by optical fiber, and we will use predominantly fiber-optic Internet. It is already widely used in Western Europe and the USA, as well as in the Russian Federation in areas of dense high-rise buildings. But the properties of fiber optic cable today allow you to connect to high-quality high-speed Internet and Vacation home.

What is fiber optic internet

Optical waveguides are used to connect it. The signal travels along them in the form of a light wave at high speed (at the speed of light). Since today all equipment transmitting and receiving signals is electronic, converters of electronic signals into optical signals and vice versa are needed. Such converters - fiber optic modems - have been developed a long time ago and are widely and successfully used.

Fiber optic cable is a unique high technology product

Fiber optic production technology dates back to the 1950s and still remains complex and labor-intensive. Therefore, the cost of fiber optic cable cannot be low. But with his help we got fast internet and the ability to use it over large areas. Huge throughput Optical cable allows you to transmit a large amount of information per unit of time. The optical signal in it is almost not distorted and does not weaken when transmitted over long distances.

In addition, the material from which fiberglass is made - quartz - is very light, durable, and is little susceptible to atmospheric influences and the influence of electromagnetic fields. Chemical inertness makes it fireproof. The disadvantages of fiberglass include:

the difficulty of repair, which is why in case of local damage to the cable it is sometimes necessary to replace it completely;
difficulty in coordinating with electrical circuits (modems are needed).

Unfortunately, these difficulties objectively lead to an increase in the cost of connecting fiber-optic communication systems.

Benefits of fiber optic internet

The remarkable properties of optical cable have determined the significant advantages of fiber-optic communication systems relative to traditional cable or DSL technologies:

very high speed of information transfer, including during peak network loads in the evenings and on weekends;
high noise immunity;
there is practically no signal delay - a delay of a few ms, while for 3G Internet the values are about 100 ms, and for satellite Internet they can reach 1000 ms;
unauthorized access to transmitted information is difficult - insertion, inductive reading and other threats;
the ability to connect video surveillance, security systems, IP telephony, interactive television, etc.;
possibility of laying fiber optic cable over long distances;
chemical resistance of fiberglass in aggressive environments;
good cable flexibility;
small dimensions and weight;
protection from open fire and explosion;
durability.

According to Point Topic, the total number of those who preferred fiber optic internet, already today exceeds the number of cable users. The listed advantages of fiber optic communication systems give rise to confidence that in the coming years the entire Internet V developed countries will become fiber optic and accessible to residents of any locality. In Russia, the Asarta company makes its contribution to this.
