QSFP+ Direct Attach Passive Copper Cable

The QSFP+ passive cable assemblies are high performance, cost effective I/O solutions for 40G LAN, HPC and SAN applications. The QSFP+ passive copper cables are compliant with SFF-8436, QSFP+ MSA and IEEE P802.3ba 40GBASE-CR4. They offer a low power consumption for short reach interconnect applications. Each cable lane is capable of transmitting data at rates up to 10Gb/s, providing an aggregated rate of 40Gb/s.
