2RS232/485/422 Fiber Modem provides 2Channel RS232/485/422 transmission on fiber. The product breaks through contradictions between traditional serial interface communication distance and communication rate besides it also can solve electromagnetic interference ground ring interference and lightning damage. The device greatly improves reliability security and confidentiality of data communication. It is widely used for various industrial control process control and traffic control occasions especially for Bank and Power and other sectors and systems which have special requirements of electromagnetic interference environment. RS232/RS485/RS422 channel can transmit adaptable serial data asynchronously 0Kbps-115200Kbps baud rate.
