NVIDIA LinkX Cables and Transceivers

800 gigabits per second (Gb/s) and 400Gb/s cables and transceivers are used for linking Quantum-2 InfiniBand and Spectrum-4 SN5600 Ethernet switches together and with ConnectX-7 network adapters, BlueField-3 DPUs, and NVIDIA DGX™ H100 GPU systems. The product line consists of direct-attach cables (DAC) reaching up to 3 meters (m), linear active copper cables from 3m to 5m, multimode optics to 50m, and single-mode optics to 100m, 500m, and 2 kilometers (km). Switches only use twin-port octal small form factor pluggable (OSFP) connectors. ConnectX-7 uses both OSFP and QSFP112, and BlueField-3 uses QSFP112 only.

200Gb/s cables and transceivers are used for linking Quantum InfiniBand and 200GbE Spectrum-2/3/4 Ethernet switches with ConnectX-6/7 network adapters, BlueField-2/3 DPUs, and DGX A100 GPU systems. The product line consists of DAC cables reaching up to 2.5m, active optical cables from 3m to 100m, multimode optics to 100m, and single-mode optics to 2km. Switches, ConnectX-6/7, and BlueField-2/3 use QSFP56 connectors.
