2m(7ft) NVIDIA/Mellanox MCP7Y60-H001(980-9I46K-00H001) Compatible 400G OSFP Finned Top to 2x 200G QSFP56 InfiniBand HDR Passive Direct Attach Copper Breakout Cable

The NVIDIA/Mellanox MCP7Y60-H001 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.

Do InfiniBand AOC cables support long-distance connections?

by 7***m on 2025-06-29 08:34:38

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 K***m on 2025-06-05 05:34:48

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.

Do these cables require special configuration after plugging in?

by B***m on 2025-04-25 13:28:30

No special configuration is needed. The cables are hot-swappable and designed for plug-and-play operation in InfiniBand environments.
