The TCF-90 is a compact media converter that transmits RS-232 signals over optical fiber. Power is derived from either the serial port or an external power source. The TCF-90 extends RS-232 transmission up to 5 km with multi-mode fiber, or up to 40 km with single-mode fiber. A pair of TCF-90 converters can be used to connect two RS-232 devices with optical fiber in full duplex mode. The optical fiber isolates the data signals from dangerous increases in ground potential, ground loops, and electrical EMI/RFI noise, and enhances data security by eliminating the harmful effects of RF radiation and susceptibility to electromagnetic radiation.
  • Use either external power or power over serial
  • Extends RS-232 transmission up to:
    • 40 km with single-mode -- TCF-90-S 
    • 5 km with multi-mode -- TCF-90-M
  • Reduces signal interference
  • Protects against electrical interference or chemical corrosion
  • 15 KV ESD protection for serial signals
  • Baudrates up to 921.6 Kbps
  • Compact size
