The Moxa PTC-101 Series are IEC 61850-3 certified industrial Ethernet-to-fiber media converters designed for reliable operation in power substations and critical infrastructure environments. These converters transform 10/100BaseT(X) Ethernet to 100BaseFX fiber and are available with SC, ST, or LC connectors for both multimode and single-mode fiber types.

The units support key features such as Link Fault Pass-Through (LFPT), redundant DC power inputs (LV models only), power failure relay output (LV only), and a wide operating temperature range from -40 to 85 °C. The built-in high-reliability power supply eliminates the need for external adapters.
