3M Cisco QSFP-H40G-ACU3M Compatible 40G QSFP+ Active Direct Attach Copper Cable.The qsfp-40g-dac-a3M direct-attached copper component (also known as dac) is suitable for very short distances and provides a cost-effective way to establish 40 gigabit link connections between devices using the qsfp port. The qsfp-dac cable is designed for 40gb/s high-speed connected network applications such as high-performance computing (hpc), enterprise networking (including the top rack switching and network storage market). It is fully compliant with qsfp and multi-source protocol (msa) standards sff-8436 and ieee 802.3ba 40gbase-cr4.

Huihong Fiber’s high-quality qsfp-dac copper cable provides a cost-effective alternative to qsfp plus transceivers and qsfp-active fibers (aoc). Qsfp-40g-dac-csc dac copper cables are programmed to be compatible with a variety of Cisco network devices for in-rack connectivity in data centers such as 40g switches, routers, network interface cards (nics) and network storage systems.

It has proven to be a cost-effective alternative to a high-cost Cisco qsfp-h40g-acu3M 40gb/s qsfp-3M dac active direct connection to copper cables.
