NVIDIA 3m 800G Twin-Port OSFP Cable

This NVIDIA MCA4J80-N003-FTF cable provides a 3 metre link between 800G InfiniBand NDR equipment. It splits a single 800G twin-port connection into two 400G OSFP interfaces for direct device attachment. The assembly uses active copper construction with a finned-top connector on one end and a flat-top connector on the other. It suits builders integrating 800G NDR switches or adapters that require this specific breakout topology.

Practical Limits of the 800G NDR Breakout

The fixed 3 metre length determines the maximum rack separation this cable can bridge without additional extenders. Active copper design constrains the usable reach compared with optical alternatives for longer runs. The twin-port to dual 400G OSFP split requires compatible port mapping on both host and target hardware. Buyers needing longer distances, different connector styles, or single-port 800G connectivity must select a different cable assembly.

Questions about this item

Should I pick the 3 m version or a different length for my rack?

The 3 m length suits typical rack-to-rack links; choose a shorter cable only if the ports are closer together.

What does the 800 G twin-port rating deliver once the cable is installed?

Each of the two OSFP ports runs at 400 G, giving an aggregate 800 G InfiniBand NDR link between the finned-top and flat-top ends.
