QDD-400-CU2 — Cisco QSFP-DD

The QDD-400-CU2 is a Cisco passive DAC (Direct Attach Copper) cable in QSFP-DD form factor, measuring 2 meters in length. It interconnects two QSFP-DD devices over short distances within a rack or between adjacent cabinets, with no optical fiber required. Its compact QSFP-DD form factor integrates natively into the latest-generation Cisco switches and routers that support this high-density connector.

Ideal for data center architectures requiring inter-device links in ToR (Top-of-Rack) or EoR (End-of-Row) configurations, the QDD-400-CU2 is suited to network engineers looking to reduce cost and latency on runs under 2 m. Genuine Cisco hardware, manufacturer warranty.
