MOXA TCF-142 Fiber Converters

MOXA TCF-142 2-Port RS-232/422/485 to Fiber Converter

The MOXA TCF-142 Series is an industrial serial-to-fiber media converter designed to extend RS-232, RS-422 and RS-485 communication over optical fiber. With support for both point-to-point and fiber-ring transmission, the TCF-142 provides a practical solution for extending serial devices across electrically noisy or physically separated industrial environments.

The TCF-142 family supports both multi-mode and single-mode fiber. Multi-mode models can provide a typical transmission distance of up to 5 km, while single-mode models can reach up to 40 km. The series also supports automatic baudrate detection, allowing the converter to continue transmitting serial data even when the connected device changes its baudrate.

Technical Specifications

RS-232, RS-422 and RS-485 Fiber Conversion

The TCF-142 provides a flexible interface for industrial serial equipment by supporting RS-232, RS-422 and RS-485. The converter can be configured for RS-232 or RS-422/485 operation, but these serial standards are not operated simultaneously. RS-485 supports both 2-wire and 4-wire configurations.

Long-Distance Optical Transmission

The TCF-142-M models use multi-mode fiber and provide a typical transmission distance of up to 5 km. TCF-142-S models use single-mode fiber and support distances of up to 40 km. Multi-mode operation uses 850 nm optical transmission, while single-mode operation uses 1310 nm.

Fiber Ring Networking

Unlike basic point-to-point serial converters, the TCF-142 can be deployed in a fiber-ring topology. Multiple converters can be connected into a ring, with a total ring circumference of up to 100 km. This architecture can help provide an efficient optical communication path for distributed serial devices.

Automatic Baudrate Detection and ADDC

The converter supports automatic baudrate detection, allowing serial communication to continue even when a connected device changes its baudrate. For RS-485 applications, Moxa's ADDC technology automatically detects and controls data direction, eliminating the need for an additional handshaking signal.

Industrial Protection and Deployment

The TCF-142 features a metal housing, IP30 protection, reverse-polarity protection and overload current protection. Standard models operate from 0 to 60°C, while wide-temperature T models support -40 to 75°C, making the series suitable for demanding industrial environments.

Available TCF-142 Models

The TCF-142 family includes different fiber and connector configurations, including TCF-142-M-ST, TCF-142-M-SC, TCF-142-S-ST and TCF-142-S-SC. Wide-temperature versions are available as TCF-142-M-ST-T, TCF-142-M-SC-T, TCF-142-S-ST-T and TCF-142-S-SC-T. Select the model according to fiber type, connector type and environmental requirements.

Applications

Compatibility Considerations

The exact TCF-142 model should be selected based on the required serial standard, fiber type, optical connector and operating temperature. The standard family includes ST and SC fiber configurations, while both multi-mode and single-mode versions are available. Always verify the fiber specification and connector before deployment.
