Fiber Optical Converter SC SMF 40km

Fibersystem media converters for RS-232 are encapsulated in corrosive protected steel which gives them a very good protection against electrical and magnetic fields. The dimensions are small and with a unique design with either nut or screw fastening of electric connector.

The media converter can easily be mounted either on a connector or directly on a cable. This give the possibility to easily mount an adapter directly on the converter for change of male/female or number of pins 9/25 pin D-sub.


  • Fiber optic transmission, immune to EMI and RFI
  • Power Supply for 110 or 230 volts
  • With or without control signals
  • Fiber connectors for SC
  • Mountable on connector or on Cable
