The US Transceivers compatible QDD-400G-ZRP 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, this module delivers 400G data rates across distances up to 1000 km over single-mode fiber, making it well suited for demanding carrier and data center interconnect deployments.
This module integrates a coherent DSP and supports flexible modulation formats including 16QAM and QPSK, enabling adaptive performance across varying link budgets. The LC Duplex connector interface and compact QSFP-DD form factor allow high-density deployment in compatible switching and routing platforms. Digital Diagnostic Monitoring (DDM) provides real-time visibility into key optical parameters for simplified network management.
The US Transceivers compatible QDD-400G-ZRP is fully TAA compliant and meets RoHS, CE, and REACH requirements, offering a cost-effective and standards-compliant alternative for metro and long-haul optical transport infrastructure.
