The US Transceivers compatible QDD-400G-LR4-S is a high-performance 400GBASE-LR4 QSFP-DD optical transceiver designed for long-reach single-mode fiber deployments. Operating over four LAN-WDM lanes across the 1295 nm to 1309 nm wavelength range, this module delivers an aggregate data rate of 400 Gbps and supports link distances up to 10 km over OS2 single-mode fiber.
Built in the compact QSFP-DD form factor, this transceiver uses an LC Duplex connector interface and incorporates Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters including temperature, voltage, TX power, and RX power. The module is TAA compliant and meets RoHS, CE, and REACH regulatory standards.
The US Transceivers compatible QDD-400G-LR4-S is an ideal solution for high-density 400G deployments in data centers, enterprise core networks, and metro interconnect applications, providing a cost-effective alternative to OEM pricing without compromising performance or reliability.
