The US Transceivers compatible QDD-400G-SR4.2-BD is a high-performance 400GBASE-SR4.2 QSFP-DD transceiver engineered for short-reach multimode fiber applications. Operating over OM4 multimode fiber, this module supports an aggregate data rate of 400Gbps across eight parallel lanes using 850nm VCSEL technology, with a maximum reach of 100 meters.<\/p>\n
Built in the compact QSFP-DD form factor, this transceiver is fully compatible with equipment requiring the QDD-400G-SR4.2-BD specification. It connects via an MPO\/MTP connector and delivers reliable, low-latency performance suited to high-density switching and routing environments. Digital Diagnostic Monitoring (DDM) provides real-time visibility into key optical parameters.<\/p>\n
This module is TAA compliant and meets RoHS, CE, and REACH regulatory standards, making it an ideal cost-effective alternative for data center interconnects, high-performance computing clusters, enterprise core networking, and cloud infrastructure deployments.<\/p>\n","protected":false},"excerpt":{"rendered":"
