On November 18, the Telecommunications Industry Association (TIA) TR-42.12 Engineering Committee on Optical Fibers and Cables issued a Call for Interest on two documents, 1) ANSI/TIA-455-191-C and 2) ANSI/TIA-492AAAF. Bullet points of the call per a TIA statement are as follows:
The TR-42.12 Committee is developing guidelines for ANSI/TIA-455-191-C, initially titled Adoption of IEC-60793-1-45 Optical Fibers- Part 1-45: Measurement Methods and Test Procedures- Mode Field Diameter as TIA-455-191 (FOTP- 191), on the following scope: "Updating the original IEC version to correct errors and adopt the newest version.”- The Committee will also develop guidelines for ANSI/TIA-492AAAF initially titled Detail Specification for Class 1A Graded-Index Multimode Optical Fibers: Modification of IEC 60793-2-10:2017, Optical Fibers - Part 2-10: Product specifications – Sectional Specification for Category A1 Multimode Fibers as defined by the following scope: “Adapting with modifications IEC 60793-2-10:2019 as ANSI/TIA-492AAAF which may include ANSI/TIA-4920000-C and addition of min EMB info from 840 – 953 nm for A1a.2 and A1a.3 fibers. The IEC standard 60793-2-10 contains details and sectional specifications which ANSI/TIA 492AAAF cancels and replaces." Additional detail specifications include:
- TIA-492A000 sectional specification
- TIA-492AA00 blank detail specification
- TIA-492AAAA, 492AAAB, 492AAAC, 492AAAD, 492AAAE
- Improving the harmonization of ANSI specs with IEC specs.
-- 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.
-- Designers, installers, integrators, operators of single pair Ethernet networks, and users.
