Cisco QDD-400-CU1.5M Compatible 400G QSFP-DD DAC Twinax Cable (1.5 meter, Passive, QSFP-DD to QSFP-DD, 30AWG)

 

The 400G QSFP-DD DAC primarily enables high-bandwidth 400G links and supports 400G Ethernet rate. It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. 400G QSFP-DD DAC cables 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. Fibermart currently offers passive copper cables in lengths of 0.5, 1, 1.5, 2, 2.5, and 3 meters.
