C. communications

Explanation:

An optical fiber is a flexible, transparent fiber made by embedding or extruding glass (silica) or plastic into a diameter slightly thicker than that of a human hair. Optical fibers are most commonly used as a means to transmit light between two points of a fiber and are widely used in fiber optic communications, where they allow transmission over distances and in a larger bandwidth (data rate) than the electric cables. Fibers are used instead of metal wires because the signals travel through them with less loss; In addition, the fibers are immune to electromagnetic interference, a problem of which metal cables suffer extensively. Fibers are also used for lighting and imagery, and are normally wrapped in packages to be used to introduce or take light out of confined spaces, as in the case of a fibroscope. Some specially designed fibers are also used for a wide variety of diverse applications, some of which are fiber optic sensors and fiber lasers.
