An optical cable transmits information through a light signal and consists of transparent fiberglass through which light travels long distances. The weakening of information impulses is insignificant.
Cable structure and advantages
The optical cable has a design similar to the electrical one, except that the central copper core is replaced with thin glass fiber, and instead of internal insulation there is a polymer base that blocks the leakage of the light signal. There is no metal braiding here, due to the uselessness of shielding electromagnetic interference. The cable is maximally protected from interference, the light signal is almost impossible to distort and it itself does not generate external magnetic radiation. It is impossible to connect to it for unauthorized reading of information.
Varieties
Fiber optic cable varies in material, conditions and location of installation (over the air, in the ground, in water). In Moscow, you can buy optical cable per meter on our website. Product thickness – 8/125 and 9/125, 50/125 and 62/125 microns. The assortment of wires includes:
- single mode. Allows you to transfer data over long distances, but the cost of equipment for connecting it will be higher;
- multi-mode. It is cheaper, but it scatters the Internet signal more and, accordingly, transmits information over a shorter distance;
- combined type.
In the production of optical fiber, innovative technologies and quality control methods are used, including reflectometers of the latest configurations. Optical cable is sold both retail and wholesale.
