The US Transceivers compatible QDD-400G-DR4-DLN is a high-performance 400GBASE-DR4 QSFP-DD optical transceiver module designed as a compatible replacement for Dell networking environments. Operating over single-mode fiber, this module delivers an aggregate data rate of 400Gbps across four lanes using 1310nm wavelength transmitters, supporting link distances of up to 500 meters.
Built around the QSFP-DD form factor, this transceiver leverages PAM4 modulation across four parallel 100Gbps lanes via an MPO/MTP connector interface, making it well suited for high-density 400G deployments in modern data centers. The module supports Digital Diagnostic Monitoring (DDM), providing real-time visibility into optical power levels, temperature, and voltage.
This US Transceivers compatible module is TAA compliant and manufactured to meet IEEE 802.3bs and QSFP-DD MSA standards, ensuring reliable interoperability in Dell-based network infrastructures. It is an ideal solution for data center interconnect, spine-leaf fabric deployments, and high-performance computing environments.
