Product Overview

The APEX 400G/200G CFP2-DCO is a high-performance coherent optical transceiver designed for next-generation metro, long-haul, and data center interconnect (DCI) networks. Leveraging advanced coherent DSP technology integrated directly into the CFP2 form factor, this module eliminates the need for external optical transport equipment, simplifying network architecture and reducing total cost of ownership.

With dual-mode operation, the module delivers 400G PM-16QAM transmission reaching up to 640 kilometers, and 200G PM-QPSK transmission extending to 2,000 kilometers. This flexibility allows network operators to optimize capacity versus reach on a per-link basis without changing hardware. The integrated SD-FEC (Soft-Decision Forward Error Correction) ensures robust performance across diverse fiber conditions.

Manufactured at our facility in Wuhan Optics Valley, each module undergoes rigorous testing and calibration to ensure consistent performance and long-term reliability in demanding deployment environments.
