With most or all of the work on the Category 8 standard finally in the rearview mirror, the Telecommunications Industry Association (TIA) recently issued a call for interest for the upcoming revision of the Balanced Twisted-Pair Telecommunications Cabling and Components Standard. The current standard, published in August 2009, is ANSI/TIA-568-C.2. With the new naming convention recently implemented by TIA TR-42, the revised standard will be ANSI/TIA-568.2-D.

“Since 2009 there have been significant advances in telecommunications cabling technology, test procedures, and expansion of the capability of balanced twisted-pair cabling to support additional applications,” the TIA stated. “ANS/TIA-568.2-D is part of the 568 family of standards, including ANSI/TIA-568.0-D Generic Telecommunications Cabling for Customer Premises, ANSI/TIA-568.1-D Commercial Building Telecommunications Infrastructure Standard, and ANSI/TIA-568.3-D Optical Fiber Cabling and Components Standard.

The TIA-568.2-D standard will, in all likelihood, incorporate the following.

  • The content of ANSI/TIA-568-C.2-1, Category 8 specifications
  • The content of ANSI/TIA-568-C.2-2, which describes alternative test procedures for Category 6A patch cords
  • Refinements to test procedures for cabling and components, as well as extrapolation to 2,000 MHz from the previous maximum frequency of 500 MHz
  • Resistance parameters that are needed for support of remote powering applications

“This document will also incorporate updated references and links to other TIA TR-42 standards that have been revised in the past five years,” the TIA said, adding that TIA-568.2-D “will supersede ANSI/TIA-568-C.2 and its addenda, ‘C.2-1 and ‘C.2-2.”

The association is actively seeking participation in this standard-revision project from the user and general interest communities. It added that stakeholders may include but are not limited to cable and connector manufacturers, end users, system developers, installers, consultants, field-tester manufacturers and users.
