The US Transceivers compatible QDD-400G-ZR-S is a 400GBASE-ZR QSFP-DD tunable coherent DCO (Digital Coherent Optics) transceiver engineered for high-capacity long-haul and metro optical networking. Operating over a tunable C-band wavelength range, this module delivers 400Gbps of throughput and supports transmission distances up to 1000km over single-mode fiber when used with appropriate amplification and dispersion compensation infrastructure.
This module integrates a built-in DSP and supports the OpenZR+ and OIF 400ZR standards, enabling simplified line-side coherent transport without the need for external transponders. The QSFP-DD form factor ensures compatibility with high-density platforms designed for next-generation data center interconnect and carrier backbone applications.
The US Transceivers compatible QDD-400G-ZR-S is TAA compliant and fully supports Digital Diagnostic Monitoring, providing real-time visibility into key optical parameters for streamlined network management and troubleshooting.
