The application of remote monitoring technology with the increasingly development of modern security technology and become more and more widely. And by the optical fiber as transmission medium of digital optical transceiver, has become the first choice in the applications of remote monitoring. This paper introduces in detail the architecture and working principle of digital optical transceiver, complete based on CPLD (complex programmable logic device) two-way uncompressed video transmission, two-way audio transmission and one-way reverse data transmission design of digital optical transceiver. Experiments show that the system performance is stable and reliable, real-time transmission effect is good, can be widely used in security industry.
