Industrial Serial RS232/RS485/RS422 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.
Features
► Plug-and-play, hot pluggable
► Extends Bi-directional RS-232/RS-485/RS-422 up to 2Km on MMF, 80Km on SMF
► EIA /TIA standard RS232/485/422, 0~2Mbps rate
► Serial data is fully transparent, baud rate is self-adaptive, no setting is required
► The high speed serial data can used for DMX512 communication in Stage Lighting Control
► Support DIN-Rail & Wall-mount installation.
► Built-in surge and static protection
► Diagnostic and unit indicator LEDs
► Environmentally Hardened -40°C to 75°C (-40°F to 176°F) operating temperature
