1m (3ft) 400G OSFP Finned Top to 2X 200G QSFP56 InfiniBand HDR Passive Direct Attach Copper Breakout Cable Compatible with NVIDIA/Mellanox MCP7Y60-H001

It is an 400Gb/s twin-port OSFP to two 200Gb/s twin-port QSFP56 InfiniBand HDR 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. The two 400G ends support 4-channels of 50G-PAM4 (200GbE/HDR) and use a flat top QSFP56 for use in ConnectX-6/7 adapters and BlueField-2/3 DPUs using riding heat sinks on the connector cage. This cable is compliant with OSFP MSA (Multi-Source Agreement) and IEEE 802.3cd 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.
