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.
