NVIDIA Mellanox LinkX Optics Ethernet transceivers are used to create high-speed, 100G-400G links supporting every configuration, reach, and speed in networks requiring detachable optical connectors. LinkX transceivers are designed to create high-speed 25G-400G optical links in Ethernet switching networks, Ethernet storage fabrics (ESF) linking hard-disk-drive (HDD) and flash memory subsystems, and NVIDIA GPU-based, end-to-end AI systems. All transceivers are extensively tested in live GPU and switching systems and used in NVIDIA-Certified Systems.
