The Moxa IMC-21-S-SC is an industrial Ethernet-to-fiber media converter that bridges 10/100BaseT(X) copper to 100BaseFX single-mode fiber using an SC connector. It’s the go-to solution when you need longer distance links, better noise immunity, and cleaner electrical isolation than copper can provide.

Why We Love This Product

• Converts 10/100 copper Ethernet to single-mode fiber for longer, more stable links
• SC connector format for straightforward patching and termination
• Industrial-grade approach for noisy environments where copper links struggle
• Simple, effective way to extend networks across buildings, yards, and plant zones

How Our Customers Use It

• Extending Ethernet from a control room to remote panels or equipment areas
• Reducing dropouts caused by EMI on long copper runs
• Connecting networks between buildings while reducing ground-loop and surge risks
• Building reliable plant backbones where distance and interference are constraints

Choosing Tips

• Choose single-mode (S) when your link distance is longer or your site standard is single-mode fiber
• Pick SC when your patch panels and leads are SC-based
• If your fiber infrastructure is multi-mode or uses different connector standards, choose the matching IMC-21 variant to avoid link issues
