MOXA Serial RS232/422/485 to Fibre Converters

Product Overview

The TCF-142 series media converters have multiple interface circuits suitable for RS-232, RS-422, and RS-485 serial copper circuits and single-mode fibre-optic cable.

These converters provide serial transmission up to 40 km over single-mode fiber (TCF-142-S). They can be configured to convert either RS-232 signals, or RS-422/485 signals, but not both at the same time.

The TCF-142 converters can automatically detect the serial data rate. Even the data rate changes, the media converter will transmit the signal with no loss of data.


  • “Ring” and “Point- to-Point” transmission
  • Enable RS-232 or RS-485 transmission up to 40 km with single-mode fibre (TCF-142-S)
  • Protects against electrical interference and chemical corrosion
  • Supports data rates up to 921.6 kb/s
