2m(7ft) NVIDIA/Mellanox MCP7H50-H002R26(980-9I99F-00H002) Compatible 200G QSFP56 to 2x 100G QSFP56 InfiniBand HDR Passive Direct Attach Copper Breakout Cable

The NVIDIA/Mellanox MCP7H50-H001R30 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.

All (3) Management (1)Product (1)Performance (1)

Can these cables be used for GPU Direct RDMA communication?

by a***m on 2025-09-18 20:29:39

Absolutely. These InfiniBand cables support GPU Direct RDMA, enabling low-latency, high-throughput data transfers directly between GPUs across the fabric.

Do InfiniBand AOC cables support long-distance connections?

by G***m on 2025-06-19 15:53:46

Yes, AOC (Active Optical Cables) support longer distances than DACs, typically up to 30 meters or more, while maintaining low latency and high bandwidth transmission.

What is the difference between HDR and NDR InfiniBand cables?

by L***m on 2025-06-01 11:22:55

HDR (High Data Rate) supports up to 200Gb/s per port, while NDR (Next Data Rate) can handle 400Gb/s. Both are used for high-performance computing, but NDR is designed for newer-generation systems requiring ultra-high bandwidth.

Worked out of the box with ConnectX-6 NICs and Quantum switches. Auto-negotiation and link detection were flawless across all ports.
