Commercial Building Telecommunications Cabling Standard Part 1 - General Requirements Addendum 7 ?Guidelines for Maintaining Polarity Using Array Connectors Addendum 7
After ANSI/TIA/EIA-568-B.1 was approved for publication, it was realized that there was
a need to explain and illustrate the concept of maintaining optical fiber polarity using
array connectors. The TIA TR-42 Engineering Committee on Premises
Telecommunications Cabling Infrastructure accepted the task and assigned it to the TR-
42.8 Subcommittee, Telecommunications Optical Fiber Cabling Systems. The TR-42.8
Subcommittee cooperated with the TR-42.1 Subcommittee on Commercial Building
Cabling, which is related to this activity, in preparing this document.
