Description
The AddOn Mellanox® MMA1U00-WS Compatible 400GBase-SR8 QSFP-DD Transceiver delivers ultra-high-speed data transmission for next-generation data center and high-performance networking environments. Designed for seamless interoperability, this transceiver provides up to 400Gbps throughput over OM4 multimode fiber (MMF) using a wavelength of 850nm and an MPO-16 connector, reaching distances of up to 100 meters.
This hot-pluggable, MSA-compliant module supports 8x50G PAM4 signaling, features a retimed 400GAUI-8 electrical interface, and includes Digital Optical Monitoring (DOM) for real-time performance insights. Built for reliability, it’s RoHS compliant, lead-free, and TAA compliant, ensuring suitability for government and enterprise applications. With low power consumption (9W) and a robust operating temperature range of 0 °C to 70 °C, it’s the ideal solution for hyperscale data centers, cloud networks, and high-bandwidth aggregation layers.
Each unit is 100% guaranteed compatible with the equivalent Mellanox® part, programmed, serialized, and tested for seamless deployment and performance parity — backed by AddOn’s limited lifetime warranty.
