1m (3ft) NVIDIA/Mellanox MCP7Y00-N001 Compatible 800G OSFP Finned Top to 2 x 400G OSFP Finned Top InfiniBand NDR Passive Direct Attach Copper Breakout Cable for Quantum-2 Switches

The NVIDIA/Mellanox InfiniBand MCP7Y00-N001 Cable is an 800Gb/s twin-port OSFP to two 400Gb/s twin-port OSFP Direct Attached Copper dual breakout cable. The 8-channel twin-port OSFP end uses a finned top form-factor for use in Quantum-2 and Spectrum-4 switch cages. This cable is compliant with OSFP MSA (Multi-Source Agreement) and IEEE 802.3ck standards.
DACs offer the lowest latency, so are widely used in data centers to connect servers and GPU compute systems to the top-of-rack (TOR) switches and link spine-to-super-spine switches inside racks over short cable lengths. DACs are also used to create InfiniBand storage fabrics with hard-disk-drive (HDD) and flash memory subsystems.
Featuring a simple design and minimal components, DAC cables offer the lowest-cost, lowest-latency, and near-zero-power connections for high-speed links. They enhance port bandwidth, density, configurability, and reduce power requirements in supercomputers and hyperscale systems.
