Abstract

The invention belongs to the technical field of communication, and provides a photoelectric conversion device and a communication system. The device comprises: a signal transmitting module and a signal receiving module; wherein the signal transmitting module comprises: an isolated input end, an encoding unit and an electro-optic conversion unit, the encoding unit encodes optical fiber data received by the isolated input end to obtain encoded data and sends the encoded data to the electro-optic conversion unit, and the electro-optic conversion unit converts the encoded data into an optical fiber data signal for transmission; and the signal receiving module comprises: a photoelectric conversion unit, a decoding unit and an isolated output end, the photoelectric conversion unit converts received optical fiber transmission data into a parallel signal and sends the parallel signal to the decoding unit, and the decoding unit decodes the parallel signal to obtain transmission data and outputsthe transmission data to an external photoelectric hybrid cable through the output end. The photoelectric conversion device provided by the invention has low power consumption and a small size, and realizes safe and fast transmission of signals, and meanwhile, the signal transmitting module and the signal receiving module can be used as transmission links and have a dual optical fiber backup function.

Description

technical field [0001] The invention belongs to the technical field of communication, and more specifically relates to a photoelectric conversion device and a communication system. Background technique [0002] When the anti-aircraft missile weapon system performs tasks, cable connections should be made between different equipment according to the task requirements. For example, in the missile test, the cables need to be connected between the missile test vehicle and the missile test control vehicle, and the number of connected cables is large. , heavy weight, which affects the speed of deployment and withdrawal of equipment, and increases the difficulty and intensity of the operator's work. In order to deal with the above problems, an optical-electrical hybrid signal transmission technology has been adopted in the prior art to solve it. Optical fiber communication is an emerging wired communication technology that uses light waves as the carrier and optical fiber as the in...
