Moxa TCF-142-S-SC ,Single-mode RS232/422/485 toFiberCon

The TCF-142 Series provides seamless RS-232/422/485 to fiber optic conversion for extending serial transmission over long distances — up to 5 km via multimode and up to 40 km via single-mode fiber. Designed for industrial use, these converters reduce signal interference, enable robust ring or point-to-point configurations, and offer advanced auto-detection and protection features.

Key Features:

• Supports point-to-point and ring fiber topologies
• Serial transmission extended via fiber: 5 km (multimode), 40 km (single-mode)
• Auto baudrate detection up to 921.6 kbps
• ADDC for automatic RS-485 data direction control
• Protection from EMI and corrosion
• Rugged IP30-rated metal housing
• Wide-temperature models available (-40 to 75 °C)
