Description
Description
The NVIDIA/Mellanox MMA4Z00-NS400 is a 400Gb/s single-port OSFP optical transceiver with a flat-top (OSFP-RHS) form factor, designed for InfiniBand NDR systems. It features an SR4 multimode parallel design using a 4-channel MPO-12/APC connector and supports 100G-PAM4 modulation, delivering high-speed, low-latency connectivity. With a reach of up to 50m over OM4 multimode fiber, it provides reliable short-reach interconnects for data-intensive environments. Engineered for supercomputing, high-performance computing clusters, and storage infrastructure, this transceiver ensures seamless integration and optimal performance. It is commonly deployed with ConnectX-7 OSFP adapters and in 2x400G InfiniBand switches to enable efficient large-scale interconnectivity.
