U.K. cable vendor Phyworks has announced it has successfully completed system level interoperability testing of its 10Gbps active equalizer in an SFP+ active copper cable assembly.

Carried out at the University of New Hampshire’s Interoperability Laboratory, the testing verified that copper cables integrating the PHY2060 active equalizer/retimer IC could achieve 100% error free transmission passing data between different switches.

In the packet error ratio test, Cisco Nexus 5020 and Arastra DCS-7124S switches were connected to each end of a 10 metre, 26AWG twin-ax copper cable assembly. Data traffic composed of 200 million 1518-byte ICMP echo requests was generated and sent across the cable at a BER of 10-12 or better. Test results confirmed that no data packets were lost.

“Data centres and system and cable manufacturers are all seeking a lower power, lower cost alternative to existing 10G optical and copper solutions for short range data links,” said Stephen King, CEO of Phyworks.

“This independent operability test, from a well respected test house, proves that copper cables can provide another solution at 10G which is better suited to shorter distances than 10GBASE-SR and CX4.”
