The "DCO" in CFP2-DCO stands for "Digital Coherent Optics," indicating its integration of a coherent optical receiver and a digital signal processor (DSP). They contribute actively to the construction of efficient and reliable. The CFP2-DCO transceiver module is an optical device that is small in size but can transmit data in a scalable and efficient manner. This device supports advanced methods of modulation and easily fits into the already existing networking infrastructure. Designed based on the CFP2 standard, it offers high-speed transmission and flexibility while maintaining a relatively larger form factor.
