Recently, many became interested infiber optic internet. Most know that this technology involves data transfer at a fairly high speed. Not so long ago, such speeds seemed to many a fantasy, although the technology of optical fiber began to develop almost a century ago - in the thirties of last century. That is why it is worth considering what is fiber-optic Internet and why this technology is out of competition.
First attempts to transfer data at a distancethrough light and transparent materials were produced as far back as 1934. Norman French was asked to convert the voice into light signals, which then will be transmitted along the rods of glass. A few years later a physicist from Switzerland, Jean Daniel Colladon, conducted an experiment with translating light through a "parabolic liquid stream", that is, water. Optical fiber in its 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 Hilu. Since they simultaneously announced their invention, all three of them began to be considered the founders of this technology. And after two years the name - fiber was invented.
The loss of light from the first optical cables wasvery large. In the late fifties, Lawrence Curtins was able to reduce them. And when in 1962 they discovered laser technology, fiber optics had another chance for existence.
Now you can return to the present. At the moment, fiber-optic Internet is characterized by an incredibly high data transfer rate. This is absolutely not surprising. The information carrier in this case is light, and its travel speed is the highest in the universe. This property must have found application, and it is. In a simplified sense, the binary code is transmitted like this: if the light is on, then this is 1, and no - then 0. The fiber-optic Internet cable transmits alternating zeros and ones at such a speed that it is simply impossible to see with the naked eye. The change of pulses is the responsibility of the transmitter, which converts electrical signals into light signals. And at the second end of the cable, the receiver is usually located, which performs the reverse transformation.
Fiber-optic Internet is characterized by hugespeed, which is its main advantage. Another advantage is the ability to work at great distances. Fiber-optic cable for the Internet is laid on the bottom of the ocean, it can stretch across the entire continent. Naturally, the architects who build it are very difficult: they install signal amplifiers at the junction points, which cost several hundred times more than the wire itself, but for the technology as a whole, such investments can not be called excessively large.
The transmission of information in this way is used andin other spheres. Through the finest wiring, you can provide backlighting during complex operations on the heart or brain of a person. The popularity of light systems, based on all the same optical fiber, is gaining popularity, but instead of information they bring sunlight to the house, which is caught from the street.
In addition to the speed and long range of information transfer, there is a similar technology and another plus - it is almost impossible to intercept data using it.
Minus there is only one - too expensiveequipment and tools for installation. The cable itself does not cost much compared to transmitters, receivers and signal amplifiers. The soldering of wires is carried out by means of special inverters, which can cost as very expensive cars.
Fiber-optic Internet is characterized by highspeed, as it was already described earlier. For home use, its minimum indicator is 10 MB / s. Physically, no home cable is capable of supporting such a speed. The best way is to use this connection if you have a home server, or if you do not have one, but several computers that constantly need access to the Internet. To separate the fiber optic cable, a special router is required. It can be used for home use or for main channels. Fiber-optic Internet will work with special routers, which were released not earlier than 2010. Their range is quite extensive, so for each user can choose the best option.
Rostelecom is not the first yearprovides citizens with access to the world wide web using ADSL technology, which involves the transmission of a signal over an ordinary telephone line. Now the operator has started to actively introduce completely new methods. Now the fiber optic Internet is being actively introduced using FTTB technology (optics up to the building). 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 is fully upgraded, each resident of the selected settlement will be able to use the full range of services. For example, there will be an opportunity to watch digital television, which at times surpasses cable and satellite quality and capabilities. A similar solution is the high quality of video materials, images and sound, as well as a convenient interactive menu, ease of use and other benefits.
At the moment, the fiber optic Internetis an advanced solution to the problem of data transmission. To surpass it in speed, only cryptosystems that are still at the design stage are capable, and it is not yet clear when their development will begin. That is why it is worth considering how to connect fiber optic Internet.
