Quellan Inc., a supplier of analog semiconductors, today announced it has achieved a 200% Reach Extension for the burgeoning 10 Gigabit Ethernet standard — a breakthrough for data centres.

At the Server Blade Summit, the company demonstrated dual-core Opteron servers populated with 10 gigabit Chelsio T210-CX Protocol Engines communicating error-free across a 50 meter Gore cable link. It also pre-announced the second generation of this technology will reach beyond 65 meters in the third quarter of this year.

The X-Ten Module is approximately the size of a matchbox and incorporates the company’s LM4602 Lane Manager embedded between two CX-4 Connectors.

The module consumes just 240mW when active and can be powered by battery, USB Cable, or an external AC transformer. The LM4602 devices can also be integrated into network adapters, servers or cable connectors.

According to the company, the reach extension is made possible by compensating for channel noise, attenuation and impairments with the company’s Collaborative Signal Processing architecture.

“Clearly, data center links are reach limited at these high data rates,” said Joel Goergen, vice president of Technology at Force 10 Networks, a manufacturer of 10 Gigabit Ethernet switch routers.

“Extending these links with low power embedded silicon is extremely valuable and will accelerate 10 gigabit copper deployments.”

The market for 10G Ethernet is expected to hit 10 million units in 2010 according to the Dell’Oro group, with almost 50% of these links being over copper.
