10GBase-CX4 or 802.3ak is a 10Gb/s Ethernet Standard designed to run over copper cabling similar to that used in InfiniBand technology. It is the lowest cost of all the 10Gb connections and uses less power than fibre optics, although the range is limited to 15 metres. Applications include high performance computing, enterprise networking and network storage.
Universal's CX4 ultra-high performance cables are manufactured by Amphenol using Fujitsu connectors and exceed CX4 standards requirements. They are compatible for use with any venddors equipment presenting CX4 interfaces and can also be used for Infiniband DDR & SDR 4X applications
