As one of the representatives for Belden, I attended the final TIA TR-42 Telecommunications Cabling Systems meeting of 2017 a few weeks ago.
With several industry experts in the room, many changes and updates to ANSI/TIA standards were discussed that will positively impact cable deployment down the road.
To keep you up to date on the latest industry happenings, here are important modifications that may affect you:
TIA TR-42.1 (Generic and Premises Cabling)
Approved for publication in June 2017, ANSI/TIA-942-B, Telecommunications Infrastructure Standard for Data Centers, has now been published. It specifies minimum requirements for data center and computer room telecommunications infrastructure.
Ongoing work in this group is giving consideration to the use of single-pair, balanced twisted-pair cable in intelligent building systems and customer premises. There are generic single-pair cabling specifications under review for two channel references: 15 m (for wireless access points, distributed antenna systems, security cameras, sensors, controls, IoT devices, etc.) and 100 m (high-speed/high-power devices, lighting and building management systems, intercoms and VoIP phones, digital signage, etc.).
TIA TR-42.3 (Pathways and Spaces)
Work is being done to support remote powering (Power over Ethernet, or PoE) in pathways and spaces such as above the ceiling, in access floors, in underfloor duct systems, in perimeter and surface-mount pathways, etc. This will allow remote powering to not only be supported in the cabling, but also throughout pathways and spaces.
TIA TR-42.7 (Copper Cabling)
Ballot comments on ANSI/TIA-568.2-D were resolved during the TIA TR-42 meeting as well. ANSI/TIA-568.2-D changes the nomenclature for the standard and combines:
TIA TR-42.11 and TIA TR-42.12 (Fiber Optic Cabling)
Addendums were made to documents, including ANSI/TIA-598-D-2, to include OM5 fiber with a lime green identifying color for the jacket.
Several Belden staff members are closely involved with the Telecommunications Industry Association, holding leadership positions within the organization. As a result, we’re always looking for ways to improve existing technology and streamline installation, helping lead industry efforts to make needed changes. If you have questions about any of the TIA TR-42 information outlined here, we’re more than happy to answer them. Just let us know!
