TCF-90 Series
Port-powered RS-232 to fiber converters

Features
- Uses either external power or power over serial
- Extends RS-232 transmission up to 40 km with single-mode (TCF-90-S) or 5 km with multi-mode (TCF-90-M)
- Reduces signal interference
- Protects against electrical interference and chemical corrosion
- Compact size
- Self-powered RS-232 to optical fiber conversion
- LED port power indicator for testing power availability
- Optional external power source support
- Full-duplex mode operation with paired converters
- Optical fiber isolation from ground potential and ground loops
- Enhanced data security by eliminating RF radiation effects
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 it enhances data security by eliminating the harmful effects of RF radiation and susceptibility to electromagnetic radiation.
