Industrial Serial RS232/RS485/RS422 Fiber Optic Modem
Industrial Serial Fiber Optic Modem Overview
Industrial RS232/RS485/RS422 to Fiber Optic Converter enables reliable long-distance serial
communication over multimode (up to 2km) or single-mode fiber (up to 80km).
This converter eliminates electromagnetic interference, ground loop issues, and lightning
damage by converting electrical signals into optical transmission. It's ideal for industrial
control, process automation, traffic management, and stage lighting systems.
Supports RS232, RS485, RS422, with strong isolation, stable performance, and wide
operating temperature range.
