The NVIDIA MMA4Z00-NS400 is a high-performance 400Gb/s single-port optical transceiver built for modern data center and high-performance computing environments. It uses an OSFP form factor and supports both InfiniBand and Ethernet protocols, making it highly versatile for different network architectures. The module is based on SR4 multimode technology, utilizing 4 channels of 100G-PAM4 modulation to deliver ultra-fast data transmission with low latency.
It operates over multimode fiber with an MPO-12/APC connector and provides a maximum reach of up to 50 meters on OM4 fiber (30 meters on OM3), making it ideal for short-distance, high-bandwidth connections inside data centers. The transceiver uses 850nm VCSEL optics and supports hot-pluggable installation, allowing easy deployment and replacement without downtime.
Designed for high-density environments, it delivers efficient power usage (around 8–9W) and supports advanced features like automatic protocol detection, digital optical monitoring, and compatibility with NVIDIA ConnectX-7 adapters and 400G switches. This makes it a reliable choice for cloud infrastructure, AI clusters, and enterprise networks requiring scalable, high-speed fiber connectivity.
