The US Transceivers compatible QDD-400G-DR4-S is a 400GBASE-DR4 QSFP-DD optical transceiver designed for high-density 400G deployments. Operating over single-mode fiber with four parallel lanes of 100G each, this module uses 1310nm wavelength transmitters to support reaches of up to 500 meters, making it well suited for intra-data-center and campus interconnect applications.
Built in the compact QSFP-DD form factor, this transceiver delivers 400Gbps aggregate throughput via an MPO/MTP connector interface. It supports Digital Diagnostic Monitoring (DDM) for real-time visibility into key optical parameters including temperature, voltage, TX power, and RX power, enabling proactive network management and simplified troubleshooting.
The US Transceivers compatible QDD-400G-DR4-S is TAA compliant and manufactured to meet IEEE 802.3bs and QSFP-DD MSA standards, ensuring full interoperability with equipment that accepts the QDD-400G-DR4-S. It is an ideal solution for data center interconnect, cloud infrastructure, and high-performance computing environments.
