Industrial Serial RS232/RS485/RS422 Fiber Optic Modem 2Km on MMF 80Km on SMF

Industrial Serial RS232/RS485/RS422 Fiber Optic Modem 

Overview

The LNK-IRS93 series is an industrial-grade fiber optic converter designed to seamlessly

transform RS232, RS485, or RS422 signals into fiber optic links. This conversion extends

the signal range up to 2 km on multimode fiber and 80 km on single-mode fiber. By utilizing

optical fiber communication, the converter effectively eliminates issues such as

electromagnetic interference, ground loop problems, and lightning damage. This

enhancement significantly boosts the reliability, security, and confidentiality of data

transmission. It is ideal for a wide range of applications, including industrial and process

control, stage lighting control, and traffic management systems.
