Shenzhen Homk Telecom Tech Co., Ltd.

2 4 8 10 Gigabit Fiber Channel 40G QSFP+ to QSFP+ Passive Direct Copper Cable DAC Patch Cord

Details

HOMK 40G QSFP+ Passive Copper Cables  are high performance,cost effective I/O solutions for 40G LAN, HPC and SAN applications.

 

The QSFP+ passive copper cables are compliant with SFF-8436, QSFP+ MSA and IEEE P802.3ba 40GBASE-CR4. It is offer a low power consumption,short reach intercon- nect applications. The cable each lane is capable of transmitting data at rates up to 10Gb/s, providing an aggregated rate of 40Gb/s.

 

40G QSFP+ Passive Copper Cables are customized for an ultra-high performance, cost effective cable solution in 40-Gigabit speed applications including switched fabric I/O, switches, routers, data storage arrays, and high performance computer (HPC) clusters.
