General Description

The FCRID-100-1DT Series are industrial grade Serial to Fiber converters that come with one fiber port (ST connector interface) which operates with two optical fibers. Both Singlemode and Multimode optical fibers types are supported. The FCRID-100-1DT Series converters can extend the transmission distance of asynchronous RS-232, RS-485 or RS-422 serial signals over optical fibers. If the Multimode optical fiber is selected, the transmission distance can be extended by 2km. Alternatively, if the Singlemode optical fiber is selected, the transmission distance can be further extended to 20km. These converters are designed to rugged and therefore suitable to be deployed at harsh environments with their higher operating temperature range.  



  • Can be mounted on DIN rail track to provide space-saving
  • Industrial grade and rugged in design with IP40 ingress protection rating
  • High operating temperature range of up to 85 degrees Celsius
  • Comes with redundant dual power inputs
  • Comes with relay output for power or link failure warning
