$442.50

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

The US Transceivers compatible MMA4Z00-NS400 is a high-performance 400GBASE-SR4 OSFP transceiver designed for short-reach multimode fiber applications. Operating over OM4 multimode fiber, this module delivers 400Gbps aggregate throughput across four parallel lanes at 850nm wavelength, supporting link distances up to 50 meters. The flat top OSFP form factor is optimized for high-density switching and compute environments requiring maximum port density.

Built to support InfiniBand NDR (Next Data Rate) as well as 400G Ethernet applications, this module is fully compliant with IEEE 802.3 and relevant MSA standards. TAA compliance makes it suitable for U.S. government and public sector deployments. The MPO/MTP connector interface enables straightforward integration into parallel fiber infrastructure commonly found in modern hyperscale and enterprise data centers.

US Transceivers compatible MMA4Z00-NS400 modules undergo rigorous testing to ensure interoperability and reliable performance, offering a cost-effective alternative without compromising signal integrity or operational stability.
