Company Introduction
This NVIDIA/Mellanox cable is a 400Gb/s dual-port OSFP to 2×200Gb/s dual-port QSFP56 HDR
InfiniBand dual-breakout high-speed cable. The 8‑channel dual‑port OSFP end is equipped with a
top‑mounted heatsink, suitable for Quantum‑2 and Spectrum‑4 switches. The two 200G ports support
4‑lane 50G‑PAM4 (200GbE/HDR) and adopt a flat‑top QSFP56 package, designed for ConnectX‑6/7
network adapters and BlueField‑2/3 with heatsink power solutions on connector racks. The cable
complies with OSFP MSA and IEEE 802.3cd standards. Featuring low latency, the 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
used to build InfiniBand storage architectures with HDD and flash memory subsystems. With a simple design and fewer components, the high-speed cable delivers cost‑effective, low‑latency,
and near‑zero power consumption high‑speed connectivity, enhancing port bandwidth, density, and
configurability in supercomputers and large‑scale systems while reducing power requirements.
