Macroreer 400G QSFP-DD Passive Direct Attach Copper Cables (DAC) primarily enables high-bandwidth 400G links and supports 400G Ethernet rate. It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. They are suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between QSFP-400G ports of switches/routers within racks and across adjacent racks.

400G QSFP-DD Passive Direct Attach Copper Cables are available with 28 AWG. Standard lengths are 0.5m, 1m, 1.5m, 2m, 2.5m, 3m.

400G QSFP-DD to 2x200G QSFP56 Breakout Passive Direct Attach Copper Cables are also available with lengths from 0.5 meter to 2 meter.



High Performance 400G QSFP-DD DAC
400G QSFP-DD Passive Direct Attach Copper Cables is the most power-efficient connectivity solution for short distance interconnects, because it is passive and has the characteristics of high reliability, low insertion loss and the lowest latency.
