Function Of Fibre Optic Cable

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.

Function of fibre optic cable.

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. One cable can have as few as two strands or as many as several hundred. Fiber optics or optical fiber refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber. A fiber optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers.

A fiber optic cable can contain a varying number of these glass fibers from a few up to a couple hundred. Optical fiber cable is widely used in fiber optic communications. The two types of fiber optic cables. Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables.

This allows long distances to be spanned with few repeaters. 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. 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 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. 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. Because light can travel for much longer distances over a fiber cable without losing its strength the need for signal boosters is lessened. Surrounding the glass fiber.
