The NVIDIA/Mellanox InfiniBand MCP7Y40-N00A compatible 800G OSFP (Octal Small Form-factor Pluggable) to 4x 200G QSFP112 direct attach cable operates over passive copper, which requires no additional power to ensure quality connectivity. This breakout cable is compliant with OSFP MSA (Multi-Source Agreement), QSFP112 MSA, IEEE 802.3ck, and CMIS v5.0 standards. It provides a high-speed connection from an 800G OSFP finned-top port typically used in switches to four 200G QSFP112 ports commonly used for NICs. 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. They are ideal for short-distance interconnections within telecom or data center equipment rooms, offering a power-efficient and cost-effective connectivity solution.
