NVIDIA InfiniBand NDR200 OSFP to 4xOSFP Splitter Active Copper Cable, 5m

NVIDIA MCA7J70 is an 800 Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) to 2 x 400 Gb/s OSFP passive Active Copper Cable (ACC) dual breakout (aka splitter) cable. The ACC uses 8-channels of 100G-PAM4 modulation and has lengths of 4 and 5 meters.
The ACC firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to. The 8-channel, twin-port, OSFP end uses a finned top form-factor for use in Quantum-2 and Spectrum-4 switch cages. The four 200 G ends support 2-channels of 100 G-PAM4 (400 G) use a flat top OSFP for use in ConnectX-7 adapters using riding heat sinks on the connector cage. For use in liquid-cooled systems, a twin-port OSFP version is available with a flat top (designated -FLT in the part number).
ACC cables are the low-cost, low-latency, low-power consuming, high-speed links next to passive DACs due to their simplicity of design and minimal components. The "active" term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters while maintaining low-latency and low-power at 1.5 Watts and 0.6 Watts. Thin 30AWG is used for 4 m lengths and thicker 26AWG for 5 m. Each end includes an EEPROM which provides product identification and characteristics to the host system.
Main use is linking an 800 Gb/s Quantum-2 switch or Spectrum-4 switch to OSFP-based 200 Gb/s ConnectX-7 PCIe network adapter cards.
NVIDIA's cable solutions provide power-efficient connectivity enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers. Rigorous cable production testing ensures good out-of-the-box installation experience, performance, and durability.
