NVIDIA IB twin port NDR 800Gb s to 2x400Gb s OSFP to 2xOSFP Flat Passive Copper Splitter Cable, 3m

NVIDIA MCA7Y00 is an 800Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) to 2x400Gb/s OSFP passive Direct Attach Copper (DAC) dual breakout (aka splitter) cable for 400Gb/s NDR InfiniBand and 400GbE Ethernet networking. It has identical design and internals as the QSFP112 version, only with different connector shells. The DAC 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 two 400G ends support 4-channels of 100G-PAM4 (400G) and use a flat top OSFP for use in ConnectX-7 adapters using riding heat sinks on the connector cage. DAC cables are low-cost, low-latency, near zero power consuming, high-speed links available due to their simplicity of design and minimal components. The "passive" term refers to the copper cable containing no electronics in the data path. Each end includes an EEPROM which provides product identification and characteristics to the host system. Main use is linking an 800Gb/s Quantum-2 switch or Spectrum-4 switch to OSFP-based 400Gb/s ConnectX-7 PCIe network adapter cards.
