Recently, many have become interested in fiber optic Internet. Most know that this technology involves the transfer of data at a fairly high speed. Not so long ago, such speeds seemed fantastic to many, although optical fiber 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 a technology is beyond competition.
A bit of history
The first attempts to transmit data at a distance through light and transparent materials were made back in 1934. Norman French was asked to convert the voice into light signals, which will then be transmitted along the rods of glass. 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 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 the Netherlands - Abraham Van Heale. 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 loss of light in the first optical cables was very large. In the late fifties, Lawrence Curtins was able to reduce them. And when laser technology was discovered in 1962, the fiber has yet another chance of existence.
Features
Now you can return to the present. At the moment, fiber optic Internet is characterized by an incredibly high data transfer rate. This is not at all surprising. The information carrier in this case is light, and its speed of movement is the highest in the Universe. Such a property must have been used, and it is. In a simplified sense, the binary code is transmitted as follows: if the light is on, then it is 1, but not then 0. The fiber-optic Internet cable transmits an alternation of zeros and ones at such a speed that it is simply impossible to see with the naked eye. For the change of pulses, the transmitter is responsible for converting electrical signals into light ones. And at the second end of the cable, a receiver that performs the inverse conversion is usually located.
Fiber optic Internet is characterized by huge speeds, which is its main advantage. Another plus is the ability to work over long distances. Fiber optic cable for the Internet is laid along the bottom of the ocean, it can stretch across the mainland. Naturally, the installers who lay it have a very difficult time: they install signal amplifiers at the joints, which are several hundred times more expensive than the wire itself, but for the technology as a whole, such investments can not be called excessively large.
Additional properties
Information transfer in this way is also used in other areas. Through the finest wiring, it is possible to provide illumination during complex operations on the heart or brain of a person. Light systems, which are based on the same optical fiber, are also gaining popularity, but instead of information, they bring sunlight into the house, which they catch from the street.
In addition to the speed and long range of information transfer, this technology has one more plus - it is practically impossible to intercept information when using it.
Fiber optic Internet: disadvantages
There is only one minus here - too expensive equipment and tools for installation. The cable itself is not so expensive compared to transmitters, receivers and signal amplifiers. The wires are soldered by means of special inverters, which can cost like very expensive cars.
Specifications
Fiber optic Internet is characterized by high speed, as described previously. For home use, its minimum rate is 10 Mb / s. Physically, no home cable can support this speed. 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. Separation of the fiber optic cable requires the installation of a special router. It can be intended for domestic use or for trunk channels. Fiber optic Internet will work with special routers, which were released no earlier than 2010. Their lineup is quite extensive, so for each user you can choose the best option.
Fiber Optic Internet (Rostelecom)
It is not the first year that 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 actively introducing completely new methods. Fiber optic Internet is currently being actively introduced using FTTB technology (optics 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 undergoes a complete modernization, each resident of the selected locality will be able to use the full range of services. For example, there will be an opportunity to watch digital television, which is many times superior to cable and satellite in quality and capabilities. Such a solution is the high quality of video materials, images and sound, as well as a convenient interactive menu, ease of use and other advantages.
conclusions
Fiber optic internet is currently an advanced solution to the problem of data transfer. Only cryptocurrencies that are still at the design stage are capable of surpassing it in speed, and it is not yet clear when their development will begin. That is why it is worth considering how to connect fiber optic Internet.
