An optical fiber (or optical fibre) is a flexible, transparent fiber made of high quality extruded glass (silica) or plastic, slightly thicker than a human hair.It can function as a waveguide, or âlight pipeâ, to transmit light between the two ends of the fiber. 9. 2  Special-purpose fiber â¢ Some special-purpose optical fiber is constructed with a non-cylindrical core and/or cladding layer, usually with an elliptical or rectangular cross-section. â¢ 3  These include polarization-maintaining fiber and fiber designed to suppress whispering gallery mode propagation.
