The Telecommunications Industry Association has created a new optical fiber test procedure standard that establishes requirements for measuring fiber.

The standard is fiber optic test procedure (FOTP)-133, IEC-60793-1-22 - Optical Fibers -- Part 1-22: Measurement Methods and Test Procedures - Length Measurement, TIA-455-133-A. The document is a revision of TIA/EIA-455-133.

FOTP-133 establishes uniform requirements for measuring the length and elongation of optical fiber, typically within the cable. The length of an optical fiber is one of the most fundamental values and shall be known for the evaluation of transmission characteristics such as losses and bandwidths.

TIA-455-133-A was created by TIA FO-4.6 Subcommittee on Optical Fibers.

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