Optical fiber Optical fiber (or "fiber optic") refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber. The preferred size for the figure-eight coil is about 15 ft (4.5 m) in length, with each loop 5 ft (1.5 m) to 8 ft (2.4 m) in diameter. This type of cable is recommended for premise applications, such as intra-building, horizontal, and backbone connections. FIBER OPTIC STANDARDS VI. As the name implies, these types of optical fibers allow multiple modes of light to travel along their axis. CATV companies use a high performance coax into the home, but it connects to a fiber optic backbone. An optical fiber is a cylindrical dielectric waveguide made of low-loss materials such as silica glass. Thus, for most applications, the fiber must be made into a cable.
