200G CFP2-DCO Tunable DWDM Coherent Module: 200G-CFP2-DCO

Our EDGEOPTIC 200G-CFP2-DCO is a multi-vendor compatible tunable C-Band DWDM coherent optical transceiver module designed for long-haul and metro network applications. The module operates in CFP2 form factor and supports flexible data rates from 100G to 200G using advanced coherent modulation formats including DP-QPSK (Dual Polarization Quadrature Phase Shift Keying) and DP-16QAM (Dual Polarization 16-Quadrature Amplitude Modulation). This coherent transceiver provides tunable wavelength capability across the full C-Band spectrum with 50 GHz ITU-T grid spacing, supporting channels 1 through 96 for both transmit and receive paths.

The 200G-CFP2-DCO utilizes an Integrated Tunable Laser Assembly (ITLA) for transmission, providing precise wavelength control across the 1528-1568nm C-Band range. The receiver incorporates an Integrated Coherent Receiver (ICR) with digital signal processing capabilities for optimal signal recovery over long fiber spans. The module achieves impressive reach capabilities: up to 2000km over standard single-mode fiber when operating at 100G with PM-DQPSK/PM-QPSK modulation, and up to 1000km at 200G using PM-16QAM modulation. The guaranteed link budget of 18dB ensures reliable performance across diverse network topologies.

A key feature of the 200G-CFP2-DCO is its integrated Digital Signal Processor (DSP) with built-in soft-decision Forward Error Correction (FEC). This integrated FEC significantly enhances transmission performance by correcting errors introduced during long-distance propagation, chromatic dispersion, polarization mode dispersion, and fiber nonlinearities. The module also incorporates Clock and Data Recovery (CDR) functionality and provides comprehensive DDM/DOM (Digital Diagnostic Monitoring) capabilities for real-time monitoring of optical power levels, temperature, and other critical parameters.

The transceiver features duplex LC/UPC connectors as the optical interface, providing standard connectivity for single-mode fiber applications. The electrical interface complies with OIF-CFP2-DCO specifications and Coherent CMIS management interface, ensuring compatibility with host systems from multiple equipment vendors. Operating within a standard 0 to 70°C temperature range and consuming a maximum of 24W, the module is designed for deployment in controlled telecom and data center environments.

Standards compliance includes MSA (Multi-Source Agreement) and OIF-CFP2-DCO specifications for coherent transceivers. The module supports OTU4 transport network applications and 100G/200G Ethernet interfaces. Typical deployment scenarios include long-haul backbone networks, metro core rings, data center interconnects requiring extended reach, and carrier-class DWDM transport systems. The tunable wavelength capability enables flexible network provisioning and wavelength routing without inventory management complexity.

Our 200G CFP2-DCO transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards. Because our focus is providing top quality service, we perform comprehensive quality checks before delivery including optical parameter measurements, connector cleanliness tests, and coherent signal quality validation. Each module undergoes rigorous testing to ensure reliable operation across the specified wavelength range and environmental conditions.
