Independent tests prove Siemon’s SFP+ cable assemblies interoperability with leading vendors’ 10Gigabit Ethernet equipment
Siemon has announced that in independent testing its high speed SFP+ direct attached passive copper cables have all passed 10 Gigabit Ethernet interoperability.
The testing, conducted by the University of New Hampshire’s Interoperability Lab (UNH IOL) confirmed interoperability with several vendors’ devices, including Brocade, Dell, Cisco, Mellanox, Arista, Arastra and F5.
The testing report from UNH IOL includes seven different SFP+ devices and five Siemon cable lengths, from 1m to 7m long. Five different link tests were performed, employing various combinations of powering up the devices under test. UNH’s finding was that all the Siemon SFP+ cables passed interoperability testing, returning an ‘A’ grade result in every single test. In addition, a Packet Error Ratio Estimation test was run to determine if any packets were lost and in every case there were no errors reported.
Explaining the choice for external validation, Dan Vout, Siemon’s marketing manager for EMEA, commented, ‘This interoperability testing is part of our ongoing programme to certify that our cables are suitable for use across a broad range of high speed networking equipment, including some equipment that may have required use of proprietary and higher cost assemblies. It will give real confidence to anyone selecting supporting infrastructure that the interoperable performance of our cables will maximise the active equipment investment.’
The SFP+ cables tested are part of ‘Siemon Interconnect Solutions’ (SIS), a high speed interconnection range. Meeting or exceeding current standards specifications, they support data transfer rates up to 10+ Gb/s per lane, as confirmed in the interoperability testing. These assemblies feature enhanced EMI shielding for low emissions, multiple conductor sizes to achieve maximum performance and ultra low crosstalk for enhanced performance.
According to Siemon, its SFP+ cable assemblies were developed specifically as a cost effective and lower power alternative to optical modules for short reach links in high speed interconnect applications, such as high performance computing (HPC) and enterprise networking, including top-of-rack switching and network storage markets.
The full SIS product line includes SFP+, QSFP+, miniSAS, QSFP+ to SFP+ Breakout, and miniSAS Fan-out passive copper cables for use in point-to-point applications in advanced data centres.

In addition, Siemon SFP+ cables were also tested by Solarfare and results are posted on its SFP+ 10GBase-CR third party listing at: www.solarflare.com/SFPplus-Transceivers-DA-Cables under ‘Table 6: Tested Third-Party 10GBase-CR Direct Attach (DA) Cables’.
