One or more glass filaments, individually relatively thick than a hair, make up a fiber optic cable. The center is the part of every strand that offers a channel for light to go through. The center is encased in the coating, a sheet of glass that bounces electrons inward to prevent network congestion and permit light to travel around curves in the wire.
Single-mode and multi-mode optic fiber connections are the two most common varieties. Single-mode optical fiber cables create light using incredibly thin glass threads and a beam, whereas multi-mode wired connections use LEDs.
Wave Division Multiplexing methods are commonly used in single-mode optical fiber systems to maximize the volume of information transmission that the strand can transport. WDM permits light of many frequencies to be joined (multiplexed) and then divided (de-multiplexed), allowing a variety of communication channels to be transmitted through one transmitted beam.
Compared to long-distance coaxial cables, fiber cables have various benefits
