Testing with Solarflare Communications confirms 10GBASE-T performance for Three Siemon Copper Cabling Systems.

Recent testing performed by Solarflare Communications confirms that Siemon’s 10G 6A UTP, 10G 6A F/UTP and Category 7/Class F TERA copper cabling systems meet or exceed all 10GBASE-T performance parameters dictated by the now ratified IEEE 802.3an-2006 standard.

Three separate Siemon cabling systems were individually tested at Solarflare’s test facility (Irvine, CA). Utilizing Solarflare’s compliant IEEE 802.3an-2006 10GBASE-T 10Xpress™ PHY products, all tests were performed on 100 meter channel lengths, based on a worst-case six around one (6A1) alien crosstalk configuration.

The 10GBASE-T standard requires that all PHY products claiming compliance with the standard perform on this 100-meter worst-case channel. More specifically, the 6A1 configuration simulates a worst-case alien crosstalk environment, with six disturber cables bundled tightly around a seventh victim cable. Full line rate 10Gb/s bi-directional Ethernet traffic was launched on each channel. A tota

l of fourteen Solarflare 10GBASE-T compliant PHY cards were required to simulate a fully stressed environment (i.e. seven PHY’s utilized on each end of 6A1 configuration).

Under these challenging worst-case conditions, Siemon’s 10G 6A UTP, 10G 6A F/UTP and TERA end-to-end solutions satisfied the 802.3an standard’s stringent bit error ratio (BER) requirements for 10Gb/s performance. The TERA S/FTP channel performed particularly well when compared to a typical category 6A UTP channel. The TERA channel exhibited on average an SNR margin of 30.2 dB, which is approximately 6 dB better than a typical category 6A UTP channel.

These tests underscore the commercial viability of 10GBASE-T by confirming overall compliance to full 802.3an system requirements as well as the interoperability of Solarflare's10 Gb/s electronics with the following cabling constructions recognized within IEEE 802.3an: Category 6A UTP, Category 6A F/UTP (screened) and Category 7 S/FTP (shielded), all with 1
