Cisco QDD-400-CU1M 1m 400GB QSFP-DD Direct Attach Copper Cable

The Cisco QDD-400-CU1M is a passive copper cable manufactured by Cisco. It features a QSFP-DD form factor on both ends and supports data transmission speeds up to 400 Gbps over a length of 1 meter.

This direct attach copper (DAC) cable is suited for short-distance, high-speed interconnects between equipment with compatible QSFP-DD ports such as switches or routers within the same rack or adjacent racks. As it requires no external power source, it reduces thermal output and simplifies cabling in dense deployments supporting port-to-port connections.
