TIA Issues Call for Interest on New Project for ANSI/TIA-492CAAC Sectional Specification for Class B Single-Mode Optical Fibers

Stakeholders Invited to Contact TIA Regarding Participation

Arlington, VA (July 8, 2019) – The Telecommunications Industry Association (TIA) TR-42.12 engineering committee on optical fibers and cables has issued a call for interest for document ANSI/TIA-492CAAC titled Sectional Specification for Class B Single-Mode Optical Fibers.

This document will adapt IEC 60793-2-50:2018 as ANSI/TIA-492CAAC. Modifications may include those described for ANSI/TIA-4920000-C and ANSI/TIA foreword including the description of new fiber categories that were not part of category 4a and 4d in TIA-492 series (B-653 (A, B), B-654 (A, B, C), B-655 (C, D, E), B-656, B-657 (A1, A2, B2, B3).

The IEC standard 60793-2-50 2018 contains detailed and sectional specifications, therefore, ANSI/TIA 492CAAC cancels and replaces: TIA-492C000, 492E000 sectional specifications; TIA-492CA00, 492EA00 blank detail specifications; and TIA-492CAAA, 492CAAB detail specifications.

TIA is actively seeking participation for document ANSI/TIA-492CAAC from the user and general interest communities.

Stakeholders may include but are not limited to: users of optical fiber such as optical fiber cable manufacturers and their customers, optical fiber transmission and test equipment manufacturers, specifiers of optical fiber and cable such as telecommunications companies and standards bodies that define transmission protocols.

A major function of the Telecommunications Industry Association (TIA) is the writing and maintenance of voluntary industry standards and specifications. These activities are carried out by the volunteer members of TIA engineering committees. Recent meeting reports, agendas and notices for upcoming meetings, as well as links to some of the most popular standards from each committee are available on TIA’s public engineering committee pages.
