QDD-4ZQ100-CU3M — QSFP-DD 400 Gbps

The Cisco QDD-4ZQ100-CU3M is a passive QSFP-DD 400 Gbps DAC cable in breakout configuration to 4 QSFP28 100G ports, over 3 m. It offers the longest reach in the QDD-4ZQ100 family (3 m vs 2.5 m, 2 m, and 1 m), enabling 400 Gbps to be distributed from a high-density switch to four 100G devices in adjacent racks. Its passive design guarantees maximum reliability with no active optical components.

The QDD-4ZQ100-CU3M is ideal for infrastructure migrations where existing 100G servers or switches need to be consolidated behind a QSFP-DD 400G port, with the flexibility to reach equipment in neighboring racks. It simplifies cabling while reducing infrastructure costs. Genuine Cisco hardware, manufacturer warranty.
