Israeli network processor company Mysticom has developed a network transceiver that can send 10 Gigabit Ethernet signals up to 10m over Category 5 cables, writes Antony Adshead.

Previously the company has transmitted error-free Gigabit Ethernet signals over 140m of Category 5 cable.

The incorporation of the transceiver into switching equipment could remove the need for cabling upgrades as enterprises look to push greater bandwidth down existing infrastructure.

Andy Rolfe, an analyst with Gartner, said, "On the downside, 10 Gigabit is a fibre-only standard and such non-standard uses have little history of success. But if this application could be adopted into the standard it could be useful for such things as server attachments. 10 Gigabit Ethernet fibre is expensive and this could lower the cost.

"The challenge for Mysticom is to get the technology taken on by the device manufacturers."

The advance comes as a result of Mysticom's development of physical layer devices which make use of the latest research into network signal transmission.

At the same demonstration at the Communications Design Conference in San Diego Mysticom also showed its transceiver pushing 10gbps over 25m of Infiniband cables.

Infiniband is a cabling standard which is being developed by the Infiniband Trade Association, which includes Dell, Hewlett-Packard, IBM, Microsoft, Sun Microsystems and several storage suppliers, with the aim of producing a method of transmission for high-bandwidth datacentre applications such as storage and server connections.

Making extra distance transmissions possible will boost Infiniband, following Intel's withdrawal from the 70-strong group earlier this year.
