The NVIDIA InfiniBand Cable is an 400Gb/s twin-port OSFP to four 100Gb/s QSFP56 Direct Attached Copper quad 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 four 100G ends support 2-channels of 50G-PAM4 (100GbE/HDR100) 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.

The FS technical team is highly professional, and their expertise has provided me with a new understanding of my network architecture. Finally, I purchased 400G cables from them to connect my NDR switch, and the connection is working well now.
