S485/232/422 serial ring network self-healing optical transceiver provides 2 RS485 ports or 1 RS232 port for bidirectional communication on the fiber ring network at the same time. Only one master station is allowed in a ring network, and the others are slave stations;Each device can choose to work in master mode or slave mode. Next, JHA Technology will give you a detailed introduction to the RS485/232/422 serial ring network optical transceiver, let’s take a look!

The RS485/232/422 serial ring network self-healing optical transceiver consists of two optical modules to form a double-ring self-healing optical fiber ring network. In the single ring network, equipment failure, power failure, or fiber breakage will not affect the normal operation of other equipment ; This product is suitable for industrial automation communication, RS485 communication in complex electromagnetic environment, long-distance RS485 equipment networking, power meter data acquisition networking and other working systems that require high reliability requirements. When a fiber breaks somewhere or a node fails, the equipment automatically switches communication to keep the communication link unblocked, which greatly improves the safety and reliability of the communication network.

485 optical transceiver provides the function of RS-232/485/422 serial port to optical fiber to realize the two-way transparent transmission of data between optical fiber and RS-232/485/422 serial port.

Due to the long transmission distance of optical fiber (multi-mode 2KM, single-mode up to 20, 40, 60KM) and strong anti-interference ability, it is the best choice for long-distance transmission to connect remote terminal unit to host and distributed centralized control system. With strong anti-interference ability, it can effectively avoid the damage to industrial data communication equipment and the interference of communication lines such as lightning strikes, surges and electromagnetic interference, and ensure the stability of the communication system
