The two characteristics of fiber- optic cable are, Signals can travel much farther than with copper wire before needing repeaters and High-speed networking standard across the industry.
Fiber optic cable, also known as fiber, has a core made up of one or more glass or plastic fibers. In 1- and 10-gigabit systems, pulsing light from a laser or an LED (light-emitting diode) is conveyed through the core fibers to transport data.
The strands contain a coating of glass or plastic around the fibers. Depending on the transmission method, different patterns of light reflection are returned to the core. The fiber can curve around bends thanks to this reflection without losing the integrity of the light-based communication.
The cladding and core are shielded by a plastic buffer outside the cladding. The buffer absorbs any light that would escape because it is opaque. Kevlar strands around the plastic buffer to stop the cable from expanding and to further safeguard the inner core. Finally, a plastic sheath is placed over the Kevlar fibers.
