The US Transceivers compatible QDD-2X400G-FR4-P is an 800G QSFP-DD optical transceiver designed to deliver high-density, high-speed connectivity over single-mode fiber. Operating as a 2x400G FR4 module, it supports an aggregate data rate of 800Gbps by utilizing two independent 400G FR4 optical channels, each leveraging four CWDM4 wavelengths ranging from 1271nm to 1331nm. This module is engineered for reliable transmission over distances of up to 2km on SMF.
Featuring dual LC Duplex connectors, this QSFP-DD transceiver provides a compact and power-efficient solution for high-capacity network deployments. It supports Digital Diagnostic Monitoring (DDM) for real-time performance visibility and is TAA compliant, making it suitable for US government and regulated enterprise procurement. Each optical channel uses EML transmitters to ensure signal integrity at 400G per lane.
This module is fully compatible with Juniper network equipment and is ideal for data center interconnect, cloud backbone infrastructure, high-performance computing networks, and enterprise core switching environments requiring 800G density.
