2m (7ft) NVIDIA/Mellanox MCP7H50-H002R26 Compatible 200G QSFP56 to 2 x 100G QSFP56 InfiniBand HDR Passive Direct Attach Copper Breakout Cable for Quantum Switches and ConnectX-6 HCA

The NVIDIA/Mellanox MCP7H50-H002R26 is an 200Gb/s QSFP56 to two 100Gb/s QSFP56 InfiniBand HDR Direct Attached Copper dual breakout cable. Using the Quad Small Form Factor Pluggable 56 (QSFP56) and contains four high-speed electrical copper pairs, each operating at data rates of up to 50Gb/s. This cable is compliant with QSFP56 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.

Note: The FS P/N is changed from Q56-2Q56PC02 to QSFP-200G-2QPC02, but the product is the same. Only the FS P/N has been changed.
