The US Transceivers compatible QDD-400G-ZR is a 400GBASE-ZR QSFP-DD tunable coherent DCO (Digital Coherent Optics) transceiver designed for high-capacity long-haul and metro optical transport applications. Operating over a tunable C-band wavelength range and supporting transmission distances up to 1000 km over single-mode fiber, this module delivers full 400G coherent performance in a compact double-density form factor.
Built to the OIF 400ZR implementation agreement, this transceiver integrates the DSP, modulator, and receiver into a single QSFP-DD module, enabling simplified network architecture and reduced power consumption. The LC Duplex connector interface supports seamless integration into coherent DWDM network environments.
The US Transceivers compatible QDD-400G-ZR is manufactured to meet or exceed OEM specifications and is TAA compliant, RoHS compliant, and suitable for deployment in data center interconnect, service provider transport, and enterprise core network applications.
