Miray MR-SFM03DS20 is a type of RS485/RS422/RS232 serial port to fiber optic Modem. Presently, many users make use of RS485/RS422/RS232 serial port fiber optic Modem to solve the electromagnetic interference in engineers and to extend the RS485/RS422/RS232 serial port transmission distance to several or even tens of kilometers. MR-SFM03DS20 can provide users with RS485/RS422/RS232 serial port end-to-end transparent transmission. Since signals are transmitted over fibers and these optical signals are free of electrical conductivity, they have strong anti-interference capacity and are immune to high-voltage power or thunders. It is widely used in industrial control, automatic electricity system, and traffic control etc.
