NSComm NVIDIA/Mellanox Compatible 800G OSFP Finned Top to 2 x 400G OSFP Flat Top Ethernet Active Direct Attach Copper Breakout Cable up to 5m(16ft)
NSComm NVIDIA/Mellanox Compatible 800G OSFP Finned Top to 2 x 400G OSFP Flat Top Ethernet Active Direct Attach Copper Breakout Cable up to 5m(16ft)
800G OSFP (Finned Top) to 2 x 400G OSFP (Flat Top) InfiniBand NDR Active Direct Attach Copper Breakout Cable (ACC/DAC)
Overview
The NSComm 800G OSFP Finned Top to 2400G OSFP Flat Top Active Direct Attach Copper (ACC/DAC) Breakout Cable is a high-density, low-latency solution for InfiniBand NDR fabrics, allowing you to split one 800G twin-port OSFP link into two 400G OSFP links. With integrated active copper and factory-terminated connectors, it simplifies deployment and reduces reliance on optical modules for short-to-medium reach interconnects.
Because NVIDIA InfiniBand is the mainstream choice for NDR AI/HPC clusters, this breakout ACC is optimized for NVIDIA (IB) environments (select NVIDIA coding on the product page), while still supporting selectable options for other platforms when needed.
The 800G OSFP finned-top end is designed for dense switch cages, while the 400G OSFP flat-top ends fit adapter-style cages that use external heatsinks. With predictable power ( 1.5W @800G, 0.6W @400G ) and a 40mm minimum bend radius, it's ideal for clean, high-performance rack cabling.
Compatibility Options (Coding) - NVIDIA Focus, Multi-Vendor Ready
-
Recommended option: choose NVIDIA (IB) coding for NVIDIA InfiniBand NDR fabrics (Quantum-2 / ConnectX-class deployments).
-
Also available: selectable coding options for other platforms (choose the matching option on the product page).
Not sure which coding you need? Contact our certified engineers and we'll help confirm the right option for your exact model.
Use Scenarios / Applications
-
Quantum-2 switch to ConnectX endpoints: break out an 800G switch port into two 400G OSFP links for GPU/server adapters in the rack.
-
Spine / super-spine short links (InfiniBand): compact NDR fabrics where switches are in the same row or adjacent racks.
-
ToR connections for GPU racks: low-latency copper links from compute systems to top-of-rack switching in AI pods.
-
InfiniBand storage fabrics: short high-bandwidth links to storage nodes where latency and cabling simplicity matter.
