RS-422/RS-485 optical fiber modem work on 1310nm wavelength using simplex single-mode optical fibers, SC, FC optical connectors for choice.
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 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-485/RS-422 optical fiberal modem provides a reliable data network.
Note: the RS-422/RS-485 interfaces cannot be used on the same unit at the same time to conve to fiber.
The RS-485/RS-422 optical fiber modem incorporates a method for automatically detecting the serial signal baud rate by hardware (Auto Baud Rate Detection). This is an extremely convenient feature for the user. Even if device baud rate is changed, the signal will still be transmitted through the RS-485/RS-422 to fiber conve er without any problem.
Fiberinthebox RS422/RS485 interfaces fiber modem meet EIA/RS-422 and RS-485 transmission standards at data rates up to 500kb/s.
Fiberinthebox can offer:
RS-232 Serial Optic Fiber Modem, RS-422 Serial Optic Fiber Modem, RS-485 Serial Optic Fiber Modem, RS-485/422 Serial Optic Fiber Modem, RS-485/422/232 Serial Optic Fiber Modem.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.
