Description
The NVIDIA MCA7J65-N004 is a 4-meter linear active copper splitter cable. It splits one InfiniBand NDR 800Gb/s twin-port OSFP into two 400Gb/s QSFP112 ports, typically linking switches to ConnectX-7 QSFP112 adapters and BlueField-3 DPUs. Rather than a high-power DSP, it uses a small pre-emphasis IC, giving it low latency, low power, and lower cost than optics.
