NVIDIA Single Port 400Gbps QSFP112 Transceiver

The NVIDIA MMA1Z00-NS400 is a QSFP112 optical transceiver with a single port that moves 400 Gb/s of data across InfiniBand or Ethernet networks. Snap it into an NVIDIA ConnectX-7 adapter, a BlueField-3 DPU, or a compatible switch slot and you gain an immediate bandwidth boost without changing your rack design or cabling layout.

The module follows the SR4 multimode specification and uses 100G-PAM4 modulation at an 850 nm wavelength. When paired with OM4 fiber and two patch panels, it supports reaches up to 50 meters, making it a practical choice for links between top-of-rack and aggregation switches, GPU servers inside the same row, or tightly grouped high-performance computing clusters.

An MPO-12/APC optical connector keeps installation straightforward and allows quick swaps during maintenance windows. Data center operators deploying large-scale AI training pods, low-latency storage fabrics, or cloud infrastructures can use this transceiver to meet demanding throughput needs while staying within the familiar multimode ecosystem.

Compliance with CMIS 4.0, Laser Class 1 safety standards, common MSA guidelines, OM4 fiber requirements, and RoHS regulations ensures the module integrates cleanly into existing environments and passes standard operational checks.
