(Transmission distanceSingle mode 0~20Km. transceiver) can help transmit RS232 signal, RS422 signal or RS485 signal in an optical fiber by converting it into optical signal, and the optical interface is an FC screw interface, which can simultaneously support 2-channel RS-485 data or 1-channel RS-422 data, for zero-latency automatic forwarding, asynchronous transmission, and point-to- multipoint application.
