Industrial Serial RS232/RS485/RS422 Fiber Optic Modem with Plug-and-play hot pluggable

Industrial Serial RS232/RS485/RS422 Fiber Optic Modem

Model: LNK-IRS93 series

Overview

The LNK-IRS93 series stands as a high-performance Industrial Serial RS232/RS485

/RS422 Fiber Optic Modem, designed to bridge standard RS232/RS485/RS422 signals

with fiber optic links, thereby extending signal transmission distances significantly—up

to 2Km over multimode fiber and 80Km over single mode fiber. As a dedicated Industrial

Serial RS232/RS485/RS422 Fiber Optic Modem, it excels in industrial environments

where reliable and secure data transmission is paramount.

By leveraging optical fiber communication, this Industrial Serial RS232/RS485/RS422

Fiber Optic Modem effectively eliminates common issues such as electromagnetic

interference, ground ring interference, and damage from lightning strikes, which are

frequent hurdles in traditional wired communication systems. This not only enhances

the stability of data transmission but also greatly boosts the reliability, security, and

confidentiality of data communication—a critical advantage in industrial settings where

data integrity is non-negotiable.

Widely applicable across diverse fields, the LNK-IRS93 series Industrial Serial RS232/

RS485/RS422 Fiber Optic Modem finds utility in industrial control systems, process

control networks, stage lighting control setups, and traffic control systems. Its robust

industrial-grade design ensures consistent performance even in harsh operating conditions,

making it a trusted solution for extending serial communication links with enhanced protection

and extended reach.
