Company Introduction
This NVIDIA/Mellanox InfiniBand cable is an 800Gb/s dual-port OSFP to 2×400Gb/s dual-port OSFP
dual-breakout high-speed cable. The 8-lane dual-port OSFP end features a top heatsink and is
designed for Quantum-2 and Spectrum-4 switches. The two 400G ports support 4-lane 100G-PAM4 (
400G) with a flat-top OSFP package, suitable for ConnectX-7 network adapters and heatsink-equipped
BlueField-2/3 modules in connector racks. The cable complies with OSFP MSA and IEEE 802.3ck
standards. Featuring low latency, this high-speed cable is widely used in data centers for short-range connections
between servers, GPU computing systems, switches, and spine-super spine switches within racks. It is
also deployed to build InfiniBand storage architectures with hard disk drive (HDD) and flash memory
subsystems. With a simple design and fewer components, the cable delivers cost-effective, low-latency, and
near-zero power consumption high-speed connectivity. It improves port bandwidth, density and
configurability in supercomputers and large-scale systems while reducing power requirements.
