Abstract

The invention discloses a method for using a vehicle-mounted optical transceiver. First, the front-end camera performs high-resolution digitalization of multi-channel video, audio and data through the audio and video transmitting module of the optical transceiver to form a high-speed digital stream, and then transmits the function of the FPGA chip. Next, the multiple digital streams are multiplexed, and the electrical signal is converted into an optical signal through the first photoelectric converter quickly, and then transmitted to the audio and video receiving module of the optical receiver through the optical fiber; the audio and video receiving module receives the signal and sends it through Receive the FPGA chip for demultiplexing, return to various digital signals, and finally restore to analog video, audio and data.

Description

technical field [0001] The invention relates to computer network transmission technology, in particular to a method for using a vehicle-mounted optical transceiver. Background technique [0002] The optical transceiver is an optical fiber communication device that extends data transmission, it is mainly through signal modulation , photoelectric conversion and other technologies, using the characteristics of optical transmission to achieve the purpose of long-distance transmission. Optical transceivers are generally used in pairs and are divided into optical transmitters and optical receivers. The optical transmitter completes the electrical / optical conversion and transmits optical signals for optical fiber transmission; the optical receiver mainly restores the optical signals received from optical fibers to electrical signal, end Cheng Guang / electrical conversion, the role of the optical transceiver is to transmit data remotely. [0003] In the military field, the trans...
