NVIDIA® MCP4Y10 is an 2x400Gb/s twin-port OSFP (Octal Small Formfactor Pluggable) to 2x400Gb/s twin-port OSFP Direct Attached Copper cable (DAC).

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. Using the Octal Small Formfactor Plug (OSFP) and containing eight high-speed electrical copper pairs, each operating at data rates of up to 100Gb/s.

The DAC firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to. EEPROMs provide product configuration information to be read by the host. Every cable length is tuned to reduce internal signal noise and back reflections.

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.
