feature a QSFP to CX4 cable connector on one end

Cable connector QSFP + based on one end and CX4 connector at the other end. Connector has QSFP to CX4 cable (Quad Small Form-factor Pluggable Plus), CX4 connector and cable SFF-8470 high quality AWG28. Compatible with QSFP + MSA SFF-8436, QDR Infiniband DDR SDR, 10 Gigabit Ethernet and 40 Gigabit Ethernet. Cable designed for professional applications. Cable length of 2m.QSFP to CX4 cable use cutting edge technology to provide a cost effective high-speed interconnect solution. At 3 times the port density of a standard SFP plug, the Quad Small Form-Factor Pluggable (QSFP) interface provides the low profile, high bandwidth, reduced power cost needed for HPC super computers and large data centers.This standard of 10GbE connection uses the CX4 connector/cabling that is used in Inifinband^TM^* networks. CX4 is a lower power standard that can be supported without a standalone PHY or optics module (the signals can be routed directly from a QSFP to CX4 cable 10GbE MAC to the CX4 connector). Due to the physical specification for CX4 based 10 Gigabit, it provides a lower latency than comparable 10GBase-T copper PHY solutions. With the use of CX4 passive (copper) cables, the nominal distance you can expect between your 10GbE links is ~10-15m.   There are also amplified 'active' (but still copper) cables with nominal distances up near 30m.
