Function Of Fibre Optic Cable

A fiber optic cable can contain a varying number of these glass fibers from a few up to a couple hundred.

Function of fibre optic cable. Techopedia explains optical fiber cable first commercially deployed in 1977 optical cable is the primary source of long distance high bandwidth communications between telephone companies multisite organizations and various other long range communications applications. A fiber optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers. A fiber optic cable also known as an optical fiber cable is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. Single mode fiber uses extremely thin glass strands as well as a laser to generate light while multi mode fiber optic cables use leds.

This allows long distances to be spanned with few repeaters. Each strand is less than a tenth as thick as a human hair and can carry something like 25 000 telephone calls so an entire fiber optic cable can easily carry several. Fiber cables rated at 10 gbps 40 gbps and 100 gbps are standard. One cable can have as few as two strands or as many as several hundred.

The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Fiber optics support a higher capacity the amount of network bandwidth a fiber cable can carry easily exceeds that of a copper cable with similar thickness. It is especially advantageous for long distance communications because infrared light propagates through the fiber with much lower attenuation compared to electricity in electrical cables. Because light can travel for much longer distances over a fiber cable without losing its strength the need for signal boosters is lessened.
