    Overview

    NVIDIA Mellanox MMS1V90-WR Overview

    The Mellanox MMS1V90-WR is a high-performance 400GbE optical transceiver designed for data center and cloud infrastructure that demand reliable long-distance connectivity. Built in a QSFP-DD (Quad Small Form-factor Pluggable Double Density) form factor, this transceiver supports 400 Gigabit Ethernet over single-mode fiber, making it suitable for large-scale spine–leaf fabrics, aggregation layers, and backbone upgrades. The MMS1V90-WR uses an 8-lane QSFP-DD host-side interface and a duplex LC optical connector on the line side, which simplifies cabling while delivering high port density for modern switches and routers. Operating at a nominal 1310 nm wavelength with LWDM4 / LR4 channels, it is optimized for up to 10 km reach over standard single-mode fiber (SMF), giving operators flexibility when connecting distributed racks, buildings, or campus facilities. PAM4 optical modulation enables efficient 400G bandwidth in a compact footprint, helping operators scale without excessive power or space consumption. The module complies with IEEE 802.3bs 400GBASE-LR8 / LR4 and QSFP-DD MSA standards and is RoHS compliant, ensuring smooth interoperability and adherence to global environmental regulations. With a commercial operating temperature range of 0°C to 70°C and a nominal 3.3 V power supply, the Mellanox MMS1V90-WR is engineered for consistent performance in enterprise, cloud, and service provider networks across Asia, Europe, Africa, and North America. Distributors, system integrators, and end users can integrate this 400GbE optical transceiver into existing Mellanox or compatible platforms to upgrade network capacity while maintaining predictable latency and stability. For detailed technical data, compatible switches, and pricing, you can access the MMS1V90-WR datasheet and consult live chat or email support to plan deployments and stock levels based on your regional project needs.
