850nm Ethernet Fiber Media Converter


SC MM Ethernet Fiber Media Converter


RS422 Gigabit Ethernet Media Converter

Industrial Serial RS232/RS485/RS422 Fiber Optic Modem


LNK-IRS93 series is an industrial grade RS232/RS485/RS422 to fiber optic converter which converts a standard RS232/RS485/RS422 signal to a fiber optic link as to extend the signal up to 2Km on multimode fiber and 80Km on single mode fiber.


The use of optical fiber communication solves the problems of electromagnetic interference, ground ring interference and lightning damage.


It greatly improves the reliability, security and confidentiality of data communication, and can be widely used in various industrial control, process control, Stage Lighting Control and traffic control occasions.




► 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
