which can range QSFP to SFP+ Cable output end

When through an increase in the frequency of the signal of the cable, the permissible length of the cable come to shorten. Accordingly, as the signal frequency increases, the differential signal before transmitted 400m quickly dropped to below 100mV.QSFP to SFP+ Cable The limiting postamplifier predictably re-zoom to the appropriate CML or LVPECL level of the input signal, even if the input level is only 5mV.Elpeus QSFP to SFP+ Cable make a great 10GbE interconnect solution by reducing hardware and power costs. These cables allow the connection of QSFP+ and SFP+ Switches and Network cards without upgrading your entire data center or storage array. They can be used to connect any QSFP to SFP+ Cable.These cables feature a QSFP to SFP+ Cable connector on one end, and a SFP+ SFF-8471 connectors on the other end.  This cable is built using high speed 30 AWG wire. Applications include 10G Ethernet, InfiniBand and Fibre Channel. We offer standard lengths of 1 to 3 meters. Custom lengths are available upon request.
