IEC recognizes Siemon's TERA as standard interface

For the second time, the International Electrotechnical Commission (IEC) has recognized the interface based on Siemon's TERA connector as the standard interface for a new high-performance class of cabling. The second edition IEC 61076-3-104 was published in preparation for the pending Class FA standard as well as ISO/IEC 15018 (generic cabling for homes).

Created by an amendment to ISO/IEC 11801, Class FA is specified to an upper frequency of 1,000MHz and is targeted to support the next generation of data applications beyond 10GBASE-T and all frequencies of CATV video. To support the future Class FA parameters, the new connector requirements specified in IEC 61076-3-104, Ed. 2.0 extend the upper frequency for balanced twisted-pair connectors from the category 7 upper limit of 600MHz to 1,000MHz.

"When the IEC first standardized on TERA for Class F/Category 7 cabling in 2003, the committee believed that it would support future applications," said Dan Mullin, Director of Siemon Labs, the company's research and development group, in a statement. "That confidence proved correct. TERA systems installed as early as 1999 are fully compliant to the recently published IEEE 802.3an 10GBASE-T standard. In fact, Class F systems are the only pre-standard installed copper systems ready to support 10GBASE-T up to 100m without additional testing or mitigation."

As a standards-recognized interface, the TERA connector is a non-proprietary solution, offered by multiple manufacturers. This non-RJ interface fits within a standard RJ-45 footprint and is easily integrated into current electronics through the use of hybrid TERA to RJ patch cords, said the press release.

TERA outlets feature a simple "tool-less" termination procedure, which allows termination times of under 4 minutes. The outlet also offers integrated quick-ground technology. During standard termination steps, the cable shield is automatically terminated, eliminating additional grounding steps. By simplifying the grounding process, said Siemon, the TERA connector allows users to benefit fully from the performance and EMI resistance of a fully-shielded solution.
