Nvidia HPE MCA4J80-N003 9.84-feet (3m) InfiniBand NDR Switch-Switch Active Copper Cable - OSFP to OSFP - 30 AWG - 800 Gbps

NVIDIA MCA4J80 is a 800Gb/s twin-port OSFP (Octal Small Form factor Pluggable)-to-2x400Gb/s twin-port OSFP Active Copper Cable (ACC) for InfiniBand NDR networking. ACC cables are the second lowest-cost, lowest-latency, very low-power consuming, high-speed links available 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 3, 4, and 5 meters while maintaining very low-latency and very low-power at 1.5 Watts per end. Thin 30AWG is used for 4m lengths and thicker 26AWG for 5m. Each end includes an EEPROM which provides product identification and characteristics to the host system. For lengths less than 3 meters, use passive DAC cables. An ACC is a passive DAC with a pre-emphasis equalizer IC included in each end, enabling cable lengths of up to 5 meters while maintaining very low-latency and very low-power at 1.5 Watts a per end. Every cable length is tuned to reduce signal noise and back reflections. The ACC firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to. The main use case for the MCA4J80 is to link two 800Gb/s Quantum-2 switches to each other (up to 5-meters). The 3-meter, flat and finned-top cable is for linking Quantum-2 switches to DGX-H100 Cedar systems.
