BlueOptics QSFP-DD Active Optical Cable 3 m, 400GBASE-SR8, Ethernet/Infiniband

BlueOptics QSFP-DD Active Optical Cable (AOC), 3 m, provides short‑reach multimode connectivity supporting 400GBASE-SR8 for high‑speed Ethernet and InfiniBand links. Designed for QSFP-DD ports, this 400G AOC is intended for data center environments where links between switches, servers and aggregation devices require consolidated high bandwidth with low latency over a 3‑meter reach.

Advantages

This active optical cable delivers high aggregate throughput with low power consumption and reduced electromagnetic interference compared with copper options. The integrated optics and standardized QSFP-DD form factor simplify installation into compatible ports without additional transceivers. Its multimode design supports typical short‑reach topologies in modern data centers and offers consistent performance for Ethernet and InfiniBand protocols.

Key specifications

How to use

Insert each QSFP‑DD module end into compatible QSFP‑DD ports on the devices to be connected, ensuring the latch engages and the optical interfaces align. Verify link status on both ends after insertion and confirm device settings for 400G operation in the network equipment management interface. For removal, release the latch and pull the cable straight out without bending the cable sharply at the connector exit.

Recommendations

Route the cable to avoid tight bends and mechanical stress; maintain the minimum bend radius specified by the manufacturer for multimode AOC assemblies. Use the 3 m length for short‑reach topologies inside racks and between adjacent racks where 400GBASE‑SR8 is supported. Check host and switch compatibility for QSFP‑DD and 400G modes before deployment and monitor link parameters after installation.
