TIA Issues Call for Interest on New Project For FOTP-226 Adoption of IEC 61746-1:2009 Calibration of Optical Time-Domain Reflectometers (OTDR) – Part 1: OTDR for Single Mode Fibers

Arlington VA (August 3, 2026) – The Telecommunications Industry Association (TIA) TR-42.13 Engineering Committee on Passive Optical Devices and Fiber Optic Metrology has issued a call for interest for document TIA-455-226-A, initially titled “FOTP-226 Adoption of IEC 61746-1:2009 Calibration of Optical Time-Domain Reflectometers (OTDR) – Part 1: OTDR for Single Mode Fibers”.

TR-42.13 is creating this project to revise TIA/EIA-455-226 by adopting IEC 61746-1:2009. This document deals with the procedures for calibrating single-mode optical time domain reflectometers (OTDR).

Stakeholders are invited to contact TIA regarding participation in the development of this and other TIA standards. The stakeholders may include, but are not limited to: fiber optic manufacturers, test laboratories, telecom users, telecom installers.

TIA is seeking broad input as per the public review announcement in ANSI’s Standards Action for directly and materially affected parties. In addition, we are actively seeking participation in this process from the user and general interest communities.
