New cabling standard recognises 28 AWG, modular plug terminated links

Wed 25 Jul 2018

  • Network infrastructure installers, building and data centre operators benefit from smaller patch cords and direct-connect attachments on cable runs
  • 28 AWG patch cords offer reduced diameter cabling providing up to double the capacity in cabinets and racks
  • Industry standard is recognition of Panduit’s research in to 28 AWG and its benefit to the network infrastructure market.

25th July 2018, London, EMEA – The TIA Copper Cabling Systems Subcommittee has approved a revision to the cabling standards that now recognizes 28 AWG patch cords as being standard compliant. Panduit, a leading global provider of network infrastructure solutions, was the first structured cabling manufacturer to introduce 28 AWG patch cords to the market and was instrumental in driving the adoption of 28 AWG solutions in the market and in drafting the new standard.

ANSI/TIA-568.2-D, the Balanced Twisted-Pair Telecommunications Cabling and Components Standard, was developed by the TIA TR-42.7 Copper Cabling Systems Subcommittee. Panduit Product Line Manager Frank Straka is a member of that committee and said. “This represents the culmination of two years of work by a broad spectrum of companies and individuals. The industry has adopted 28 AWG patch cords and sees the value. It’s a highly positive move that we have a new standard that reflects that.”

Upon publication, the new standard will replace ANSI/TIA-568-C.2. Publication is expected within the next month.

One major change with the ANSI/TIA-568.2-D is that it recognizes 28 AWG patch cords as being standard compliant. This means:

  • Patch cords can be made from 28 AWG cable
  • Maximum channel lengths must be de-rated from their maximum 100-metre length when using 28 AWG patch cords (for example, 10 metre 28 AWG patch cord can be used with 82.5 metre horizontal cable, for a 92.5 metre channel).

Horizontal cable in 28 AWG is not included in the updated standard. Cable gauges of 22-24 AWG will still be required for standard-compliant horizontal cable.

Panduit launched the first 28 AWG patch cords on to the market in 2011. Since that time, the market has quickly adopted the reduced-diameter patch cords, which have met all performance standards, but were considered non-compliant due to wire gauge.

‘We are excited to see the industry formally recognize 28 AWG patch cords,” said Ralph Lolies, Managing Director, Panduit EMEA. Our customers have long understood that the true value of 28 AWG isn’t the small size, but what that size means in higher cable densities, improved cable management, better air flow and easier installation and management.  Standardising 28 AWG ensures that our customers will continue to be able to deploy these cables knowing they meet industry recognized performance requirements.”

In addition, the standard also recognized modular plug termination links (MPTL) as being standard compliant. Modular plug terminated links refer to permanent links where a plug is directly terminated to horizontal cable and plugged into a device. These modular plugs, including Panduit’s Field Term Plug, simplify the connection of devices such as security cameras and wireless access.
