NVIDIA LinkX Cables and Transceivers

InfiniBand and Ethernet interconnects for 100G/200G/400G and 800G infrastructures.

Explore the industry’s most complete line of Ethernet and InfiniBand interconnects with exceptional low latency, low power, and reliability for AI and accelerated computing. NVIDIA® LinkX® products can link upward in NVIDIA Quantum and Spectrum™ architectures for switch-to-switch applications, downward for top-of-rack switch links to ConnectX® smart network adapters, and to BlueField® DPUs in compute servers and storage subsystems.

Product Lines

400Gb/s OSFP (100G-PAM4 Modulation)
InfiniBand and Ethernet

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.
