NVIDIA InfiniBand NDR200 OSFP to 4xOSFP Splitter Active Copper Cable

The NVIDIA MCA7J70-N005 is an 800 Gb/s active copper splitter cable built for environments where every watt and every rack unit count. It takes a single switch port that uses a twin-port OSFP connector and breaks it out into four independent 200 Gb/s OSFP links, giving network architects a straightforward way to increase server density without adding extra switch hardware.

The cable relies on active copper technology with built-in equalization, maintaining low latency while reaching up to five meters. Even at its full length it draws only 1.5 W, so large clusters can enjoy high-throughput connections without a noticeable impact on power budgets.

Each of the eight 100G-PAM4 lanes can auto-negotiate for InfiniBand or Ethernet traffic. An onboard EEPROM supplies clear identification and configuration data to switches and adapters, removing manual steps during deployment.

Physical construction also aligns with modern data center requirements. A jacket made from low-smoke zero-halogen material supports strict safety policies, and the 26 AWG copper conductors meet RoHS guidelines while preserving signal integrity.

Deploy the cable when you need to link a Quantum-2 or Spectrum-4 leaf switch to four OSFP-based ConnectX-7 adapters in the same rack or to a neighboring rack. High-performance computing clusters, AI training nodes, and storage servers all benefit from the bandwidth, minimal latency, and straightforward breakout topology that the MCA7J70-N005 provides.
