Optical connector	ST -

The Moxa TCF-142-M-ST-RM is an insert module for the NRack system, specifically developed for converting serial data transmission protocols into fiber optic signals. It serves as a serial-to-fiber optic converter and enables the transmission of RS-232, RS-422, or RS-485 signals over fiber optic cables. The module is designed for use in the TRC-190 housing, a modular rack system designed for industrial networking applications. The conversion is performed via a multi-mode optical connection with ST connector, enabling flexible integration into existing fiber optic infrastructures.

Applications

The TCF-142-M-ST-RM is designed for industrial environments where reliable, interference-free data transmission over long distances is required. Typical application scenarios include networking control systems, sensors, machines, or peripheral devices in production facilities, power supply networks, or transportation infrastructures. The use of fiber optic cables instead of copper cables reduces electromagnetic interference and enables higher transmission stability, especially in environments with high electromagnetic noise.

Functions and Equipment in Detail

The module performs the conversion of serial interfaces (RS-232, RS-422, RS-485) into a fiber optic signal, enabling data transmission over fiber optic cables. The support of multiple serial protocols allows flexible connection to various devices. The conversion is bidirectional, enabling data transmission in both directions. The ST connector is a standard in industrial fiber optic technology and ensures a secure mechanical connection.

Technology Explained Simply

The converter transforms electrical signals from serial interfaces into optical signals transmitted over fiber optic cables. This is achieved via an integrated transceiver that converts electrical pulses into light pulses and vice versa. The use of multi-mode fiber optic cable enables transmission over medium distances, with the exact range depending on the fiber optic cable quality and transmission parameters. The ST connector is robust and easy to connect, simplifying installation and maintenance in industrial applications.

Compatibility and Accessories

The module is specifically developed for the TRC-190 housing and is integrated as an insert module into this system. It is part of the TCF-142-RM series, which includes various variants for different fiber optic and connector types. Compatibility with the TRC-190 housing is predefined, allowing the module to be directly installed into the existing rack system without requiring additional adapters or converters.

Installation and Mounting

Installation is performed by inserting the module into the TRC-190 housing. Mechanical fixation is achieved via the rack system, while electrical and optical connections are directly attached to the respective ports. The serial interface is connected to the device to be linked, while the fiber optic side is connected to the fiber optic cable via the ST connector. Configuration is performed via the interface of the TRC-190 housing or through external control options provided by the respective system.

Operational Advantages

Using fiber optic cables instead of copper cables offers higher resistance to interference, especially against electromagnetic interference. Transmission over fiber optic cables enables longer range without signal loss, facilitating networking over greater distances. The modular design allows flexible system expansion, as additional converter modules can be easily installed into the TRC-190 housing. The ST connector is robust and suitable for industrial use, increasing reliability during operation.
