TIA 458 : B1990

The development of fiber optic communications systems and the associated components (such as cables, connectors, couplers, attenuators, isolators, and wavelength-division multiplexing/demultiplexing devices, as well as light sources and detectors) will be facilitated if optical fiber types are standardized, and if the number of fiber types is minimized. The selection of fiber type (single-mode and multimode) is governed by a number of factors that impact system performance, reliability, and cost. Specifies optical fiber core and cladding material classes, plus preferred sizes, for optical communication applications.
