optical fiber cable

Optical fibers are used instead of metal wires, where data travels at a higher level of safety than conventional wires in terms of risk of loss, and are protected against electromagnetic interference suffered by metal wires heavily.It was first used to transmit telephone communications in 1977. Optical fibers are used to transmit images from small, hard-to-reach places

The optical fiber consists of three things: the heart, a thin glass in which light travels, the "reflector", a material that surrounds the glass core and works to reverse the light back to the center of the optical fiber, and the "protective cover", a plastic wrap that protects the optical fiber from moisture. Or protect it from damage and breakage, and then collecting hundreds of these optical fibers lined together in a bundle to be a photovoltaic cord that protects with an outer cover called a jacket.
