Siemon's SFP+ Direct Attached Copper Cable Assemblies Pass Interoperability Testing with Multiple 10Gigabit Ethernet Equipment Manufacturers

Watertown, CT — Siemon's SFP+ direct attached passive copper cables have been tested by the University of New Hampshire's Interoperability Lab (UNH IOL) and passed their 10Gigabit Ethernet interoperability testing with several vendors' devices including: Brocade, Dell, Cisco, Mellanox, Arista, Arastra and F5.

The report includes seven different SFP+ devices and five Siemon cable lengths from one to seven meters long. Five different link tests were performed employing various combinations of powering up the devices under test. All cables passed interoperability testing. In addition, a Packet Error Ratio Estimation test was run to determine if any packets are lost and there were no errors.

This interoperability testing is part of Siemon's on-going program to certify our cables are suitable for use across a broad range of high speed networking equipment including some equipment that may require use of proprietary and higher cost assemblies.

Siemon's high speed Interconnect product line includes SFP+, QSFP+, miniSAS, QSFP+ to SFP+ Breakout, and miniSAS Fan-out passive copper cables for use in point to point applications advanced data centers.

The UNH report is available at:

In addition, Siemon SFP+ cables were also tested by Solarfare and are posted on their SFP+ 10GBASE-CR third party listing at: under "Table 6: Tested Third-Party 10GBASE-CR Direct Attach (DA) Cables."
