CX4 Cables and Infiniband 10G peers for maximum network

{
}

10GBase-CX4 is an IEEE specification for 10 Gigabit over coaxial cable, intended to connect servers, switches and storage over short distances of up to 15 metres/50 feet. 10GBase-CX4 or 802.3ak uses the Infiniband 4X connector to maximize signal strength and can support data transfers of up to 10 Gigabits per second, 10 times as fast as gigabit Ethernet. It combines low cost cables and equipment with high speed for short distance connections. Applications include inter-switch, switch to server and storage CX4 Cables are tested to a higher test standard than are InfiniBand cables. Therefore, CX4 cables are backwards compatible to Infinband, but Infiniband cables do not necessarily meet CX4 test standards.Deploying newer 40-Gigabit QSFP and QSFP+ technology into an exsiting 10-Gigabit CX4 Infiniband environment can be a dicey situation.

Fortunately, we offer QSFP to CX4 hybrid cables to smooth the transition. Your QSFP and QSFP+ equipment will auto-detect the CX4 10GbE connection and adjust the I/O speed accordingly. Upgrade your backbone to 40G and relax while the auto-negotiate happens with your interconnects to CX4 and Infiniband 10G peers for maximum network throughput. Each cable is MSA compliant, fully tested and includes our lifetime warranty.CX4 was the first 10G copper standard published by 802.3. It uses the XAUI 4-lane PCS connector and copper cabling. It is specified to work up to a distance of 15 m (49 ft). Each lane carries 3.125 G baud of signaling bandwidth. 10GBASE-CX4 offers the advantages of low power, low cost and low latency, but has a bigger QSFP-4SFP1?0G-CU1M – Compatible Cisco QSFP+/4SFP?+ Copper Cable Breakout, 1 Meter form factor than the newer SFP+ standard and a much shorter reach than fibre or 10GBASE-T.
