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.
