In practice

Built for the work.

NVIDIA MCA7J60 active copper splitter: twin-port OSFP head splitting into two flat-top OSFP ends

Use case

Reach NDR servers beyond passive splitters

Connect a QM9700 twin-port OSFP cage to two GPU servers with ConnectX-7 MCX75310AAS-NEAT adapters over 4 m. It suits layouts where servers sit too far from the switch for a passive MCP7Y00 splitter, without moving to optics.

Integration

Twin-port OSFP to 2x OSFP, 800G

Connector 1 is a twin-port OSFP for the switch; connector 2 is two OSFP plugs for 400G NDR adapters, carrying 800 Gbit/s total (2x 400G) over 4 m of active copper. Lenovo 03NV639 is equivalent to NVIDIA MCA7J60-N004.
