The invention provides a connector module and optical signal processing device connected thereto. The optical signal processing device and the connector module are connected together via at least one fiber cable, they are allowed to transmit at least one optical signal therebetween. The connector module comprises a circuit board, a high frequency connector, and at least one photoelectric transducer. The high frequency connector and the photoelectric transducer are configured on the circuit board in a way of COB. Accordingly, the high frequency connector and the photoelectric transducer are implemented on the circuit board in the way of COB, which can effectively reduce the volume and the manufacture cost of the connector module. Besides, the connector module is capable of transmitting signals in the way of optical communication so as to improve the data transfer rate and transmission distance of the connector module.
