Belden IBDN™ System 10GX™ Validated During Live, 3rd Party Demonstration of 10GBASE-T Technology

Share Article

At 100 meters, and using the worst-case channel configuration scenario specified by the TIA, the Belden 10GX 10-Gigabit Structured Cabling Solution performs error free.

Belden, a world leader in the design, manufacture and marketing of signal transmission solutions for data networking and a wide range of specialty electronics markets, announces history in the making: In September 2006, Belden participated in a full fledged, live demonstration of 10GBASE-T technology at Solarflare™ Communications in Irvine, California. The tests were performed using Solarflare’s newly-developed 10Xpress™ 10GBASE-T PHY evaluation boards.

The validation trials were performed on a 100-meter Belden IBDN System 10GX channel in a worst-case, 4-connector channel configuration (as specified in the TIA augmented Category 6 draft standard, which is currently under development in the TIA TR 42.7 subcommittee). A 7-cable (six-around-one) configuration was used, with the Belden 10GX cables bundled every eight inches.

The 10 Gb/s Ethernet signals were generated using a traffic generator at the XAUI interface to the PHY evaluation boards. The 10Gb/s Ethernet signal was looped back at the far end transceiver and the receiver frames compared to the sending frames. Live 10GBASE-T traffic was transmitted simultaneously on all six neighboring channels simulating a worst-case alien crosstalk environment. There were no errors detected for the duration of the testing, which lasted over several hours. The Signal-to-Noise Ratio monitored during the testing was in excess of 25 dB, providing a good margin over the standard.

This truly marks the first real life test to demonstrate the performance capability of 10GBASE-T, using Solarflare’s 10GBASE-T product over Belden’s 10GX augmented Category 6 cabling. A real-life example of what this means would be the difference of transmitting high resolution pictures (600 dpi) at 20 per minute at 1 Gb/s, versus 200 per minute at 10 Gb/s.

The Belden IBDN System 10GX is not an improved or boosted Category 6 system, but a revolutionary new solution designed around a series of dynamic enabling technologies to ensure the highest level of alien crosstalk isolation and the best electrical performance during high frequency operation.
