Testing with Solarflare®
Communications Confirms 10GBASE-T Performance for Three Siemon®
Copper Cabling Systems
Watertown, CT and Irvine,
CA – January 17, 2007 –
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
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 total 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).
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.
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 100
meter reach. The two companies will conduct testing on Category 6 UTP at 55
meters in the future.
"Siemon’s extensive research and design capabilities were
highlighted by Solarflare’s results,” states Daniel J Mullin, Director of
Siemon Labs™, the company’s R&D arm. “In addition to our 10G6A UTP
solution, the verification of 10G 6A F/UTP and TERA systems confirms the
market practicality of screened and shielded systems. This is a great
validation of Siemon's expertise and significant investment in screened and
shielded technologies over the years “.
Bruce Tolley, vice president of marketing at Solarflare, “the successful
testing of Siemon’s three copper cabling products paves the way for many
enterprise data centers and networks to cost-effectively move to
high-performance 10 Gigabit Ethernet, It’s another important step toward
market adoption of this key technology.”
Solarflare is the first
company to publicly demonstrate 100-meter, standards-compliant 10GBASE-T
products, and the first company to deliver samples to customers. These
customers require 100 meter reach on their cabling system and demand support
of and interoperability with the 10GBASE-T standard. Solarflare products
undergo a rigorous test and validation process to ensure 10GBASE-T
compliance and 100 meter performance. The 6 around one testing with Siemon
shows how robust the 10Xpress solution is at 100 meters.
