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.
