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 networking. 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 capacity in a compact double-density form factor.<\/p>\n
Built to the OpenZR+ MSA and OIF-400ZR specifications, this transceiver integrates a complete coherent modem with DSP, enabling plug-and-play deployment without external amplification over metro distances. The QSFP-DD form factor ensures compatibility with high-density line card and router platforms that require maximum port density at 400G speeds.<\/p>\n
The US Transceivers compatible QDD-400G-ZR is TAA compliant and fully tested to meet or exceed OEM performance standards, making it a reliable and cost-effective solution for Data Center Interconnect, carrier metro networks, and enterprise core backbone deployments.<\/p>\n","protected":false},"excerpt":{"rendered":"
