The Telecommunication Industry Association has adopted IEC-60793-1-50, Optical Fibers -- Part 1-50: Measurement Methods and Test Procedures -- Damp Heat (Steady State), as an American national standard, fiber optic test procedure (FOTP)-160, TIA-455-160-A.

The document is a revision of TIA/EIA-455-160 and replaces TIA/EIA-455-161.

This part of IEC 60793 provides a practical method for evaluating optical fiber performance in a defined environment. The purpose of this standard is to determine the suitability of optical fiber (types A1a to A1d and B1 to B4) to withstand the environmental condition of high humidity and high temperature that may occur in actual use, storage and/or transport.

The test is intended primarily to permit the observation of effects of high humidity at constant temperature over a given period. The applicability of this test to other fiber types is under study.

TIA-455-160 was adopted by TIA-FO-4.6 Subcommittee on Optical Fibers and released September 2003.

The TIA is based in Arlington, VA. For more information, visit www.tiaonline.org.
