Description

High-performance 400G active optical cable for NDR InfiniBand links. OSFP-to-OSFP design with 850 nm multimode optics delivers low latency and stable throughput for HPC, AI, and fabric backbones. Flat-top heatsink variant fits tight-clearance OSFP cages. Ideal for short intra-rack and adjacent-rack connections and validated for NVIDIA Quantum-2 switches and ConnectX-7 adapters with OSFP ports.

Features

400G aggregate bandwidth for NDR InfiniBand fabrics
- OSFP-to-OSFP integrated AOC simplifies deployment—no separate transceivers or patch cords
- 850 nm multimode optics provide low latency and EMI immunity
- Flat-top heatsink option for dense chassis and limited vertical clearance
- Plug-and-play with NVIDIA OSFP NDR platforms
- Power-efficient design with digital diagnostics for easy monitoring

FAQs

Q: Is this cable compatible with 400G NDR InfiniBand ports?
A: Yes. It is designed for NDR (400G) InfiniBand OSFP ports such as those on NVIDIA Quantum-2 switches and ConnectX-7 adapters.

Q: What is the difference between FLT and non-FLT versions?
A: FLT indicates a flat-top heatsink for tight-clearance OSFP cages; non-FLT uses a finned heatsink for maximum thermal headroom.

Q: Can this OSFP AOC be used in QSFP56/QSFP28 cages?
A: No. OSFP and QSFP form factors are not physically compatible.

Q: Does this support Ethernet as well as InfiniBand?
A: Functionally it aligns with 400G OSFP AOC ports, but operation depends on platform coding and AOC support. Verify with the switch/NIC vendor.

Q: Is this a breakout cable?
A: No. It is a straight OSFP-to-OSFP 400G AOC. For breakouts, use specifically coded breakout assemblies.
