200G/100G Coherent CFP2-DCO Transceiver – Up to 1000 km / 2000 km
The CFP2-200G-DCO is a high-performance coherent CFP2-DCO optical transceiver designed for long-distance DWDM transmission in metro, regional and DCI networks. The module supports flexible 100G and 200G transmission, with reach beyond 1000 km at 200G and up to 2000 km at 100G over single-mode fiber.
The transceiver integrates coherent DSP functionality and supports PM-16QAM, PM-QPSK and PM-DQPSK modulation together with SD-FEC. It is designed for installation directly into CFP2-DCO compatible host systems, eliminating the need for an external coherent transponder in suitable applications.
