What is QSFP-DD CFP2 DCO DWDM coherent optical module?

The QSFP-DD CFP2 DCO DWDM coherent optical transceiver module is a high-performance optical module used for fiber optic communications.  CFP2 represents its size and interface type, while DCO represents the application of digital coherent light technology. It combines digital signal processing (DSP) technology and coherent optical communication technology to transmit large-capacity data at high speed and with high stability.

 The QSFP-DD CFP2 DCO DWDM coherent optical module can achieve a transmission rate of up to 400Gbps, and the transmission distance is compatible with 120KM-1200KM. Due to the compact size of CFP2, this optical module has a high degree of integration and can support more in a limited space. interfaces and channels to provide higher port density.

 The digital coherent optical module uses DCO technology to demodulate and re-modulate the optical signal through digital signal processing to realize the recovery of the optical signal at the receiving end and the shaping of the signal at the transmitting end. This technology can improve transmission distance and signal quality, and overcome dispersion and nonlinear effects in fiber transmission.

 DWDM (Dense Wavelength Division Multiplexing) enables optical modules to transmit multiple independent optical signals simultaneously, each occupying a different wavelength. This greatly increases the transmission capacity of fiber optics, allowing the network to carry more data traffic.

  FIBERTOP's QSFP-DD 400G CFP2 DCO DWDM coherent module is designed for ZR 400G DCI/PTN applications and ZR+200G metro long-haul OTN applications. It provides high-speed data channels, IIC interface modules and high-capacity fiber optics. High-speed data channel, IIC interface module control and status alarm reporting, using 3.3 V power supply.

 The QSFP-DD coherent optical module uses a 76-pin connector as the electrical interface to connect to the system board. All control interface pins work properly with the help of internal MCU, which itself can also be used for modulator control, software. The module includes TX unit, RX unit and control unit.
