The PTC-101 Ethernet-to-fiber media converters convert from 10/100BaseT(X) to 100BaseFX. Models are available with either SC. ST. or LC connectors. The PTC-101 converters eliminate the need for additional wiring. and support IEEE 802.3 and IEEE 802.3u/x protocols with 10/100M. full/half-duplex. and MDI/MDI-X auto-sensing to provide a total solution for your industrial Ethernet networks. The PTC-101 is compliant with the essential sections of EN 50155. covering operating temperature. power input voltage. surge. ESD and vibration.- 10/100BaseT(X) auto-negotiation and auto-MDI/MDI-X- Link Fault Pass-Through (LFP)- Power failure alarm by relay output (LV model only)- 40 to 85°C operating temperature range- Redundant dual DC power inputs- Integrated high-reliability power supply eliminates the need for external power transformer- Compliant with EN 50121-4 and essential sections of EN 50155
