Design Research of Digital Optical Transceiver in Mine Network Platform

In order to solve problems of high cost of network wiring of existing mine monitoring and control system and resource waste, the paper introduced the structure of mine network platform based on B/S mode which took digital optical transceiver as core, gave hardware design scheme of digital optical transceiver based on CPLD, and used MaxpusII to simulate bidirectional transmission of video signals, audio signals and data signals.The simulation result showed that the design scheme of mine-used digital optical transceiver has clear multiplexing timeslot distribution and has no message overlapping or loss,which satisfies triple-play.
