Siemon releases Cisco compatible SFP+ direct attached copper cable assemblies for 10GbE applications

Whilst Siemon’s industry standard passive SFP+ DAC assemblies have been tested and proven for interoperability through independent testing by the UNH Interoperability Lab, these new cables are programmed specifically to work with all Cisco network equipment having 10GBase-CX1 ports, including Catalyst and Nexus switches. When these cables are plugged into Cisco equipment, they will not trigger the warning message that a non-Cisco or third party DAC has been detected. Importantly, these cables do not impact Cisco’s warranty.

As 10 gigabit per second (Gb/s) SFP+ DACs and transceivers become common for top-of-rack (ToR) applications in the data centre, where small access switches or port extenders connect directly to servers, Siemon’s Cisco compatible SFP+ DACs were developed specifically as a cost effective and lower power alternative to optical modules for these short reach, high speed interconnects. Ideal for high performance computing (HPC) in networking and storage environments, these standard compliant assemblies easily support transfer rates up to 10+ Gb/s per lane with ultra low crosstalk for enhanced performance.

Like all Siemon SFP+ DACs, the Cisco compatible SFP+ DACs combine a twinaxial shielded cable construction with robust die-cast housing, superior strain relief and gold plated contacts for enhanced support at higher frequencies with minimised EMI leakage.
