Description

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.

Applications

  • Industrial Automation: Seamlessly integrates serial devices with fiber-optic networks for machine control and monitoring systems.
  • Access Control Systems: Extend communication between devices in building security, such as card readers and security panels.
  • Public Transport & Tolling Systems: Ensures reliable data communication for ticketing and toll collection in remote or high-traffic locations.
  • Smart City Solutions: Enables robust communication for urban infrastructure systems, including traffic monitoring and environmental sensors.
  • Banking & Self-Service Kiosks: Provides a stable, interference-free connection for critical systems like ATMs and self-checkout machines.
  • Heavy Industry: Connects industrial machines, sensors, and controllers in harsh environments, ensuring high-performance communication.
