When it becomes necessary to transfer data from one remote point to another, more and more instead of the traditional copper wire, the contractor offers the customer to lay an optical cable. Today we’ll talk about this interesting technology.
Fiber optic communication lines (FOCL) operate on the principle of transmitting a light wave through a special channel made of highly pure, quartz glass. Electrical pulses of electronic equipment are fed to a signal converter, which generates a stream of light flashes and transfers them to the cable. At the other end, the receiver receives the light flux and transcodes it back into electromagnetic pulses. Since the entire process is electronically controlled and is a digital conversion, distortion is minimal.
To build such FOCLs, they use a special material - single-mode fiber and multi-mode.
