Cisco QSFP-4SFP10G-CU1M Compatible 40G QSFP+ to 4x10G SFP+ Passive Direct Attach Copper Breakout Cable.Qsfp-4sfp10g-dac-p1m qsfp plus 4xsfp plus direct connection copper tap cable assembly (also known as dac) is suitable for very short distances and provides a cost-effective way to interconnect devices using the qsfp-port and sfp-port. The qsfp-to-4xsfp-dac tap cable is designed for 40gb/s high-speed interconnect network applications such as high-performance computing (hpc), enterprise networking (including the rack top switching and network storage market). It is fully compliant with qsfp and multi-source protocol (msa) standard sff-8436 and sfp-msa sff-8431.
This passive DAC cable does not have signal amplification built into the cable assembly. Qsfp-4sfp10g-dac copper cables are programmed to be compatible with a wide range of Cisco network devices for in-rack connectivity in data centers such as Ethernet switches, routers, network interface cards (nics) and network servers.
It is a cost-effective alternative to the high-cost Cisco QSFP-4SFP10G-CU1M 40Gb/s QSFP plus 4XSFP-1M DAC tap-in cables.
