Mellanox - Network splitter

NVIDIA MCP7Y10 is an 800 Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) -to- 2x 400 Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) passive Direct Attach Copper (DAC) dual breakout (aka splitter) cable for 400Gb/s NVIDIA End-to-End Infiniband and Ethernet solutions. It has identical design and internals as the Single port OSFP 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 QSFP112 for use in ConnectX-7 adapters and BlueField-3 DPUs using riding heat sinks on the connector cage.

DAC cables are the lowest-cost, lowest-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. Every cable length is tuned to reduce internal signal noise and back reflections.

Main use is linking an 800 Gb/s Quantum-2 switch or Spectrum-4 switch to QSFP112-based 400 Gb/s ConnectX-7 PCIe network adapters cards and BlueField-3 DPUs.

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 best out-of-the-box installation experience, performance, and durability.
