The Moxa TCF-142-S-SC converts serial signals (RS-232/422/485) to single-mode fiber, letting you push serial communications over long distances with excellent noise immunity. It’s a smart move when copper runs are unreliable, distances are too long, or you need to electrically isolate equipment across sites.

Why We Love This Product

• Moves serial traffic onto single-mode fiber for long-range, low-noise comms
• SC fiber connector format for straightforward patching and termination
• Fiber ring support helps improve network resilience in serial-over-fiber deployments
• Industrial operating range (0 to 60°C) suits control cabinets and plant environments

How Our Customers Use It

• Extending serial devices between buildings, yards, and remote plant areas
• Improving reliability where EMI makes copper serial runs unstable
• Isolating serial equipment to reduce ground-loop issues and site-to-site noise
• Creating resilient serial links in ring topologies for higher uptime

Choosing Tips

• Choose the single-mode (S) model when you need longer fiber distances than multi-mode typically supports
• Pick SC when your site standardises on SC patch panels and leads
• If your fiber infrastructure is multi-mode, select the matching multi-mode TCF variant to avoid link issues
