Overview
The MOXA TCF-142-S-SC Fiber Optic Converter enables secure, long-distance serial communication by converting RS-232/422/485 signals into single-mode fiber. Designed for electrically noisy or distributed environments, it provides complete immunity to EMI/RFI interference and supports fiber ring redundancy for high-availability networks.
With MOXA’s ADDC® automatic data direction control for RS-485, installation is simplified and configuration requirements are reduced. Its rugged design, wide temperature options, and reliable optical transmission make it a trusted choice for system integrators working on industrial automation, SCADA, transportation, and energy systems.

Application
The TCF-142-S-SC is widely used in environments where serial devices must communicate reliably over long distances or where electrical noise prevents stable copper-based communication. Typical applications include:
-
Factory Automation – Extends serial links between PLCs, sensors, and distributed I/O across large production areas.
-
Transportation Systems – Provides robust communication for signaling, diagnostics, and wayside monitoring equipment.
-
Energy & Utilities – Connects SCADA and DCS components within substations, switchyards, and remote plants.
-
Oil & Gas – Ensures secure, interference-free transmission in hazardous and EMI-intensive zones.
-
Smart Infrastructure – Supports fiber ring redundancy for high-availability communication loops.
Engineers often select this converter for SCADA environments, where long-distance fiber connections eliminate interference and improve communication reliability between remote stations.
