The US Transceivers compatible QDD-400G-LR8-S is a 400GBASE-LR8 QSFP-DD optical transceiver engineered for high-density, long-reach data center and enterprise network deployments. Operating across eight wavelength lanes in the 1295 nm to 1309 nm range using LAN-WDM technology, this module delivers an aggregate data rate of 400 Gbps over single-mode fiber at distances up to 10 km.
Built in the compact QSFP-DD form factor, this transceiver uses an LC Duplex connector interface and supports Digital Diagnostic Monitoring (DDM) for real-time visibility into key optical parameters including temperature, voltage, TX power, and RX power. It is fully compliant with IEEE 802.3bs and relevant MSA standards.
The US Transceivers compatible QDD-400G-LR8-S is TAA compliant and RoHS certified, making it suitable for government procurement and environmentally regulated environments. Ideal applications include data center interconnect, enterprise core networking, and high-capacity metro aggregation.
