This QSFP+ (Quad Small Form-factor Pluggable Plus) copper direct-attach cables are suitable for very short distances links and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ports of QSFP+switches within racks and across adjacent racks.

These cables are used for 40GbE and Infniband standard. QSFP+ are designed to meet emerging data center and high performance computing application needs for a high density cabling interconnect system capable of delivering an aggregate data bandwidth of 40Gb/s.

This interconnect system is fully compliant with existing industry standard specifications such as the QSFP+ MSA and IBTA (InfiniBand Trade Association).

The QSFP+ cables support the bandwidth transmission requirements as defined by IEEE 802.3ba (40Gb/s) and Infiniband QDR ( 4x10Gb/s per channel)specifications.
