NVIDIA4M OSFP to OSFP InfiniBand NDR Network Cable

Overview

The NVIDIA MCA4J80-N004 is an InfiniBand NDR network cable designed to connect two OSFP-equipped devices, delivering data transfer speeds up to 800 Gbit/s. This active copper cable spans four meters, maintaining signal integrity without the need for optical transceivers, making it an efficient choice for high-performance computing clusters, machine learning environments, and enterprise data centers where devices are located within the same or adjacent racks.

Its direct electrical connection reduces latency and simplifies network maintenance, allowing optical ports to be reserved for longer-distance links. Installation is simple, involving plugging the OSFP connectors into compatible switches or adapters and securing the cable along standard routing paths.
