The US Transceivers compatible MMS1V90-WR is a 400GBASE-LR4 QSFP-DD optical transceiver designed for high-density, long-reach network deployments. Operating over single-mode fiber, this module delivers an aggregate data rate of 400Gbps across four wavelength channels using LAN-WDM technology, supporting link distances of up to 10km. The QSFP-DD form factor enables backward compatibility and high port density in modern switching and routing platforms.
Built to meet IEEE 802.3bs and QSFP-DD MSA standards, this US Transceivers compatible module supports Digital Diagnostic Monitoring (DDM) for real-time visibility into key optical parameters including temperature, voltage, TX power, and RX power. TAA compliant and manufactured to RoHS, CE, and REACH requirements, it provides a reliable, cost-effective alternative for data center interconnect, enterprise core networking, and cloud infrastructure applications.
