Belden today announced results of a live demonstration of 10GBASE-T technology at Solarflare Communications in Irvine, Calif. 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 receive frames compared to the sending frames.

According to Belden, 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.
