Optical fiber is the fastest information transmission technology on the Internet today. The structure of an optical cable has certain features: such a wire consists of small, very thin wires, shielded with a special coating, which separates one wire from another.
Light is transmitted along each wiring, which transmits data. An optical cable is capable of simultaneously transmitting data, in addition to an Internet connection, also television and a landline phone.
Therefore, the fiber-optic network allows the user to combine all 3 services of one provider, connecting the router, PC, TV and telephone to a single cable.
Another name for fiber optic connection is fiber optic communication. Such a connection makes it possible to transmit data using laser beams over distances measured in hundreds of kilometers.
An optical cable is made up of tiny fibers with a diameter of thousandths of a centimeter. These fibers carry optical beams that carry data by passing through the silicon core of each fiber.
Optical fibers make it possible to establish connections not only between cities, but also between countries and continents. Internet communication between different continents is supported by fiber optic cables laid along the ocean floor.
Fiber optic internet
Thanks to optical cable, you can set up a high-speed internet connection, which plays a huge role in today's world. Fiber optic wire is the most advanced technology for transmitting data over a network.
Optical cable advantages:
- Durable, high bandwidth, conducive to fast data transfer.
- Security of data transmission - fiber optic allows programs to instantly detect unauthorized access to data, so access to them for intruders is almost excluded.
- High immunity to interference, good noise suppression.
- The structural features of an optical cable make the data transfer rate through it several times higher than the data transfer rate through a coaxial cable. This primarily applies to video and audio files.
- When connecting optical fiber, you can organize a system that implements some additional options, for example, video surveillance.
However, the most important advantage of a fiber-optic cable is its ability to establish a connection between objects located at a great distance from each other. This is possible due to the fact that the optical cable has no restrictions on the length of the channels.
Internet connection using fiber optic
The most widespread Internet in the Russian Federation, the network of which operates on the basis of optical fiber, is provided by the provider Rostelecom. How to connect fiber-optic internet?
First, you just need to make sure that the optical cable is connected to the house. Then you need to order an internet connection from your provider. The latter must provide the data that provides the connection. Then you need to configure the equipment.
It is done like this:
- After conducting the fiber and connecting the equipment that ensures operation in optical passive networks, the employees of the provider company, all subsequent configuration is performed independently.
- First of all, the yellow cable and socket are installed as shown in the figure below.
- You can have your own Wi-Fi router, it is not necessary to purchase a router from Rostelecom. A fiber optic cable, an optical terminal and a main cable are connected to Wi-Fi, through which the router is connected to an optical outlet.
- Choose as much ventilated place as possible to install all equipment. The installer from the provider should indicate where exactly the network elements are to be installed.
The terminal is equipped with a special socket that allows you to connect to a computer and connect the router to the Internet.
In addition, the terminal has 2 additional sockets that allow you to connect an analog home telephone to the fiber-optic connection, and several more sockets are provided for connecting a television.
