NVIDIA MMA1Z00-NS400-T 400GbE QSFP112 MPO12 APC 850nm | Enterprise Optics

Keep high-throughput east-west traffic moving with a 400 GbE optical module designed for short-reach multimode deployments. The NVIDIA MMA1Z00-NS400-T uses a QSFP112 form factor, MPO12 APC connector, and 850 nm wavelength to support up to 50 m over MMF. That combination fits tightly packed leaf-spine fabrics, GPU clusters, and other environments where every rack unit and every port count. This transceiver is built for teams that need predictable optical performance without overbuying reach they will never use. Short-reach MMF keeps cabling simpler and cost controlled, while the 400 GbE data rate preserves headroom for modern storage, AI, and compute traffic. The flat-top design also aligns with high-density hardware layouts where airflow and physical clearance matter. Choose this module when you need a precise fit for 400 GbE interconnects and a clean path to scale inside the data center. It is a focused optics choice for environments that value bandwidth, density, and disciplined infrastructure design.
