RealSea’s 40G QSFP+ (Quad Small Form-factor Pluggable Plus) active direct-attach copper cables are suitable for very short distances and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ ports. QSFP+ are designed for a high density cabling interconnect system capable of delivering an aggregate data bandwidth of 40Gbps. This interconnect system is fully compliant with QSFP+ MSA. The QSFP+ cables support the bandwidth transmission requirements defined by IEEE802.3ba (40Gbps).
