MMS4X00-NM, NVIDIA Mellanox NVIDIA Twin Port Transceiver, Optical Transceiver

The Mellanox MMS4X00-NM is a high-performance optical transceiver module designed for 800G InfiniBand NDR data center and HPC connectivity. Built for NVIDIA and Mellanox networking platforms, this OSFP finned module delivers up to 800 Gb/s (2x NDR) over single-mode fiber, making it ideal for demanding cloud, AI, and research workloads. It uses 2x MPO optical connectors at 1310 nm wavelength and supports links up to 500 m over SMF, giving operators a simple way to scale leaf-spine and backbone architectures without redesigning existing fiber plants. For distributors and system integrators in Asia, Europe, Africa, and North America, the MMS4X00-NM offers a consistent, standards-based option that fits modern high-density switches and adapters. Its OSFP finned form factor helps manage thermal performance in dense racks, while the dual MPO interface allows flexible breakout and structured cabling layouts. End users benefit from predictable low-latency InfiniBand NDR links that keep GPU clusters and storage fabrics running at full speed. Whether you are building a new NDR fabric or upgrading an existing Mellanox environment, the MMS4X00-NM provides reliable bandwidth, long-reach SMF support, and smooth integration with NVIDIA InfiniBand platforms, helping to protect your network investment and simplify large-scale deployments.
