$450.50

SKU: MMA4Z00-NS400-T-US Categories: , , OEM Equivalent: Nvidia MMA4Z00-NS400-T

The US Transceivers compatible MMA4Z00-NS400-T is a high-performance 400G OSFP transceiver engineered for InfiniBand NDR and high-speed data center environments. Housed in an OSFP form factor, this module delivers 400 Gbps aggregate throughput across four parallel lanes using 850nm VCSEL-based optics, supporting multimode fiber links up to 50 meters.

Designed as a drop-in replacement, the US Transceivers compatible MMA4Z00-NS400-T supports SR4 parallel optic architecture with an MPO/MTP connector interface, making it ideal for short-reach, high-density interconnects within spine-leaf and HPC fabric deployments. Digital Diagnostic Monitoring (DDM) provides real-time visibility into module health and performance parameters.

Built to meet stringent compliance requirements including TAA, RoHS, and CE standards, this module offers a cost-effective and reliable alternative for organizations deploying InfiniBand NDR or 400G Ethernet infrastructure at scale.
