$500.00

SKU: MMS4X00-NS400-US Categories: , , OEM Equivalent: Nvidia MMS4X00-NS400

The US Transceivers compatible MMS4X00-NS400 is a high-performance 400GBASE-DR4 OSFP transceiver designed for single-mode fiber deployments supporting InfiniBand NDR applications. Operating over four parallel lanes at 100G per lane using 1310nm wavelength, this module delivers reliable 400G connectivity at distances up to 500 meters over SMF, making it well suited for demanding high-performance computing and data center environments.

Built in the OSFP form factor with an MPO/MTP connector interface, this transceiver leverages PAM4 modulation to achieve maximum signal integrity across extended reaches. The flat top housing design supports optimized airflow and thermal management in high-density switch and server deployments. Digital Diagnostic Monitoring (DDM) provides real-time visibility into key optical parameters for simplified network management.

The US Transceivers compatible MMS4X00-NS400 is TAA compliant and manufactured to meet RoHS, CE, and REACH standards, offering a cost-effective and fully compatible alternative for 400G InfiniBand NDR infrastructure upgrades.
