The NVIDIA InfiniBand Cable is an 2x 400Gb/s twin-port OSFP to four 200Gb/s twin-port QSFP112 Direct Attached Copper 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 200G ends support 2-channels of 100G-PAM4 (200G) and use a flat top QSFP112 for use in ConnectX-7 adapters and BlueField-3 DPUs using ridiing heat sinks on the connector cage. This cable is compliant with OSFP MSA, QSFP112 MSA (Multi-Source Agreement) and IEEE 802.3ck 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.
