RS-232/RS-485/RS-422 interface optic fiber modem is the best choice to connect RTU to HOST or SCADA controllers via multi-mode or single-mode optical fiber. The RS232/RS422/RS485 fiber conve er can extend serial transmission distance up to 2km (multi-mode fiber) or up to 20km (single-mode fiber).
With resistant to the effects of lightning strikes, power surges and other electromagnetic interference, the RS-232/RS-485/RS-422 optical fiberal modem provides a reliable data network.
Those above Serial Optic Fiber Modem can work on 1310nm wavelength using duplex single-mode fibers, duplex multi-mode fibers or simplex single-mode fiber. And they have FC or SC connectors for choice.
