QDD-400-AOC25M — QSFP-DD 400 Gbps

The QDD-400-AOC25M is a Cisco Active Optical Cable (AOC) in QSFP-DD form factor, transmitting 400 Gbps over 25 m. This pre-terminated cable combining active optics with QSFP-DD connectivity offers an intermediate reach between short DAC cables and long-distance optical modules, with greater deployment flexibility than copper.

The 25 m length suits medium-sized datacenters where inter-bay distances exceed the reach of passive DAC cables but do not yet justify a standalone optical module. Ideal for inter-row connections or feeds from a central patch panel. Genuine Cisco hardware, manufacturer warranty.
