TIA TIA-492A000-A PDF

This Specification applies to Class la graded-index, multimode optical fibers with glass core and cladding. These fibers are defined as having a refractive index profile which varies with radius from the center of the core and has a profile parameter, g, whose value is 3 greater than or equal to g greater than or equal to 1.

Class la fibers are used in long-haul telecommunications links with moderate bit-rates, and in short-length links for data communications and local area networks.

This Specification, Basic Specification EIA/TIA-455-A and its addenda, Generic Specification TIA/EIA-4920000-B, Blank Detail Specifications, and all Detail Specifications derived from the first four listed Specifications shall follow the specification structure used in the U.S. National Electronic Components Quality Assessment System (NECQ).
