| Abstract: | This paper introduces the design of 4 channel digital intrinsically safe video optical fiber transceiver. This design uses single opti- cal fiber transmission with no compression technology to transfer 4 channel video signal, and realizes the intrinsically safe design of hardware circuit. The optical fiber transceiver is composed of optical transmitter and optical receiver, which has advantages of low price, convenient installation, stable transmission signal, etc. |
