Abstract

A pair of data optical fiber transmission equipment based on CPLD is designed and developed. The video, gigabit network, RS422 and other multi-channel data are formed into high-speed data stream, and then the multi-channel digital stream is carried out wavelength division multiplexing and transmitted through the transceiver integrated optical terminal machine. The receiving optical terminal is demultiplexed and restored to multiplex individual digital signals, At full load, one channel of video, two channels of gigabit networks and five channels of RS422 are transmitted. Duo to the complex application environment of the optical terminal computer, the state of bidirectional data transmission information needs to be reported in real time. In this paper, a real-time fault detection method is designed for the entire optical fiber transmission link. The video locking state of optical terminal machine, the output voltage state of linear voltage regulator and the transmission fiber between two optical terminal machines are monitored in real time and is applied to a certain type of vehicle photoelectric system. The fault location is accurate and timely, and the application effect is good.
