The US Transceivers compatible QDD-4X100G-FR-S is a high-performance 400G QSFP-DD optical transceiver engineered for demanding data center and enterprise network deployments. Operating across four 100G lanes using 1310nm wavelength optics, this module delivers an aggregate data rate of 400Gbps over single-mode fiber with a maximum reach of 2km, making it well suited for campus and metro interconnect applications.
Built to the QSFP-DD form factor, the US Transceivers compatible QDD-4X100G-FR-S supports 4x100G FR operation using four independent lanes of LAN-WDM optics via an LC Duplex connector interface. The module incorporates Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters including temperature, voltage, bias current, and optical power levels.
This transceiver is TAA compliant and manufactured to meet RoHS, CE, and REACH regulatory standards, ensuring compatibility with federal procurement requirements and global deployment environments. It is a cost-effective, drop-in replacement designed to operate seamlessly in systems that accept the QDD-4X100G-FR-S.
