Video optical transmitter and receiver and detecting method for video optical transmitter and receiver

Abstract

The invention provides a video optical transmitter and receiver which comprises an optical transmitter, an optical receiver, a fault indicating module and a fault detecting module, wherein the fault detecting module comprises a communication fault detecting module; the communication fault detecting module is used for detecting if the video optical transmitter and receiver, to which the fault detecting module belongs, and the last video optical transmitter and receiver connected with the video optical transmitter and receiver are normally communicated; and when the video optical transmitter and receiver and the last video optical transmitter and receiver connected with the video optical transmitter and receiver are abnormally communicated, the fault indicating module is controlled to indicate the fault. The video optical transmitter and receiver in fault is detected by the fault detecting module in the video optical transmitter and receiver provided by the invention. No professional technician is required for detecting and maintaining on the site by using special test equipment or disassembling the equipment which is confirmed as being problematic by the professional technician and sending to a manufacturer for detecting, so that the fault is timely eliminated, the influence on the use of the video optical transmitter and receiver is avoided while the maintenance cost is saved.

Description

technical field [0001] The present application relates to the field of optical transmission technology, and in particular to a video optical transceiver and a detection method for a video optical transceiver. Background technique [0002] Video optical transceivers used for uncompressed long-distance transmission of images in the video image monitoring industry have experienced two generations of development. The first generation is an analog video optical transceiver based on FM (Frequency Modulation, frequency modulation) technology, and the second generation is based on A digital video optical transceiver based on video digitization and non-compression time-division multiplexing technology. The digital video optical transceiver solves the shortcomings of analog video optical transceivers such as low transmission capacity, low business capability, easy signal attenuation, easy crosstalk, and poor product consistency. [0003] However, once any problem occurs during the us...
