Overview
The LNK-IRS93 Series is an industrial-grade serial-to-fiber converter supporting RS232,
RS485, and RS422 protocols. It extends serial communication up to 2 km on multimode
fiber or 80 km on single-mode fiber, ensuring reliable, interference-free data transmission in
harsh industrial environments. Ideal for process control, stage lighting (DMX512), and traffic
systems, it provides plug-and-play operation with hot-swappable support and built-in
surge/ESD protection.
