Description

High-bandwidth 400G active optical cable with QSFP-DD connectors on both ends for spine-leaf, storage, and AI/ML clusters. 850nm optics enable reliable 20m runs with lower weight and power than copper alternatives. Suitable for QSFP-DD 400G Ethernet and InfiniBand environments. Blue jacket aids fast identification in high-density racks.

Features

- 400G throughput with eight 50G PAM4 lanes
- 20m reach for extended intra-row connectivity

FAQs

Q: What applications suit a 20m AOC?
A: Row-to-row connections, spine-to-leaf aggregation, and links where 10m is insufficient and installing patch fiber plus transceivers is unnecessary.

Q: Does it support breakout to 8x50G?
A: This is a straight 400G QSFP-DD to QSFP-DD AOC. Breakout requires a purpose-built breakout AOC or optics.

Q: Can this be routed alongside power cables?
A: It is immune to electromagnetic interference, but follow best practices: maintain separation to ease service and avoid physical damage.

Q: Is vendor coding required?
A: It is QSFP-DD compliant. Check device transceiver coding policies for any vendor-lock requirements.
