Fiber Optic Cable



Fiber optic cable is a cable that uses glass or plastic fiber cable to transmit data in the form of light, allowing transmission over longer distances and at higher data transfer rates than other forms of wired and wireless communications. Fiber optic cable has many advantages over its predecessors (copper and electric wires); for example, light pulses in optical fibers are not affected by radiation in the surrounding environment, in turn significantly reducing error rates. Similarly, fiber optic cable allows signals to travel greater distances before the signal has to be regenerated (repeated).
