TIA Issues Call for Interest on a New Project for Fiber Optic Terminology

Arlington VA (June 30, 2026) – The Telecommunications Industry Association (TIA) TR-42.5 Engineering Committee on Telecommunications Infrastructure Terms and Symbols has issued a call for interest to reaffirm document ANSI/TIA-440-C, initially titled “Fiber Optic Terminology”.

TR-42.5 is reaffirming this document. The purpose of this Standard is to define commonly used terms, symbols and abbreviations for fiber optic applications. The revision is required to update definitions, add new definitions, and correct errors.

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: Designers, installers, manufacturers

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.
