The PTC-101-S-SC-LV from Moxa is an industrial media converter that converts Ethernet signals in the standard 10/100BaseT(X) via an RJ45 network connection into 100BaseFX fiber optic signals. The device is designed for use in demanding industrial environments, particularly in power supply networks, substations, and industrial automation. It meets the requirements of the IEC 61850-3 standard, specifically developed for substations and critical infrastructures, thus ensuring reliability under extreme conditions such as high temperatures, ESD effects, voltage surges, and mechanical vibrations.

Applications
This converter is suitable for applications requiring stable and long-distance data transmission over fiber optic cables, for example in power supply, monitoring of electrical grids, or process automation. Its ability to operate at temperatures from -40 to 85 °C makes it suitable for outdoor use or in industrial halls where high or low temperatures may occur. The integrated power supply and redundant DC input function (only LV models) enhance operational safety in critical installations.

Functions and Features in Detail
The PTC-101-S-SC-LV features an RJ45 interface for connecting to an Ethernet network and a 100BaseFX fiber optic interface with SC connector. The conversion is performed with Auto-Negotiation and Auto-MDI/MDI-X, enabling automatic adaptation to the network topology. The Link Fault Pass-Through (LFPT) function ensures that in case of a fiber optic connection failure, the Ethernet network also indicates the fault, simplifying troubleshooting. In case of power failure, a relay output is activated (only LV models) to inform external systems of the failure.

Technology Explained Simply
Optical transmission occurs in multimode format (1300 nm) with a range of 4 to 5 km and in singlemode format (1310 nm) with a range of up to 40 km. The TX power is -10 to -20 dBm in multimode and 0 to -5 dBm in singlemode. The RX sensitivity is -32 dBm (multimode) and -34 dBm (singlemode), providing high receiver sensitivity and thus reliable signal transmission even over long distances. The link budget is 12 dB (multimode) and 29 dB (singlemode), describing the maximum attenuation the system can compensate for. The saturation levels are -6 dBm (multimode) and -3 dBm (singlemode), indicating the maximum input power at which the device still functions correctly.

Compatibility and Accessories
The converter is compatible with standard Ethernet networks and fiber optic infrastructures. The SC connector enables easy integration into existing fiber optic networks. Power supply is via DC inputs in the range of 20 to 72 VDC (LV model), with redundant inputs available. The integrated power supply is equipped with overcurrent protection. The devices are designed for DIN rail mounting, enabling flexible installation in enclosures.

Mounting and Installation
Mounting is done via a DIN rail, enabling quick and secure installation in standard enclosures. The metal housing provides mechanical protection and is designed for use in industrial environments.

Operational Advantages
The high operating temperature range of -40 to 85 °C, integrated power supply, redundant power supply (LV model), and relay alarm function in case of power failure increase the availability and reliability of the device. Compliance with IEC 61850-3 and certifications according to EN/UL 62368-1, UL 60950-1, EN 55032/35, FCC Part 15B, CISPR 32, as well as IEC 61000-4-2 to -4-11, ensure safety and EMC compliance. The MTBF is 4,660,534 hours according to Telcordia SR332, highlighting high service life and reliability. The 5-year manufacturer's warranty provides additional security for the operator.
