The Moxa PTC-101-M-ST-HV is an industrial Ethernet-to-fiber media converter designed for use in demanding environments such as power supply networks, substations, and industrial automation systems. The device converts Ethernet signals in the format 10/100BaseT(X) into fiber optic signals in the format 100BaseFX, enabling the connection of copper and fiber networks. It is specifically developed for operation in accordance with the standard IEC 61850-3, which imposes high requirements for electromagnetic compatibility, operating temperature, and reliability in power plants. The integrated high-performance power supply eliminates the need for external power units, simplifying installation and increasing system reliability.

Applications
This media converter is suitable for industrial networks, particularly in power supply applications, where high electromagnetic compatibility and operational reliability are required. The robust construction with metal housing and DIN rail mounting allows for easy integration into existing enclosures. The operating temperature range of -40 to 85 °C makes the device suitable for extreme environmental conditions, such as those encountered in outdoor installations or unregulated industrial facilities.

Functions and Equipment in Detail
The device features an RJ45 port for 10/100BaseT(X) and a fiber optic port with ST connector. Support for multimode and singlemode fibers enables flexible adaptation to existing infrastructures. With multimode fibers (1300 nm), the maximum reach is up to 5 km; with singlemode fibers (1310 nm), it is up to 40 km. The Link Fault Pass-Through (LFPT) function ensures that a signal loss at the Ethernet port is also indicated at the fiber port, simplifying network diagnostics. Power supply is provided via the HV type, supporting voltages from 100–240 VAC/VDC, ensuring broad compatibility with various power supplies.

Technology Explained Simply
The integrated power supply of the PTC-101-M-ST-HV reduces the number of components required in the enclosure and minimizes potential failure points. Auto-Negotiation and Auto-MDI/MDI-X ensure automatic adjustment of transmission speed and cable direction, eliminating the need for manual settings. Optical characteristics, such as TX power of -10 to -20 dBm for multimode and 0 to -5 dBm for singlemode, and RX sensitivity of -32 dBm (MM) and -34 dBm (SM), ensure stable signal transmission over the specified distances. The saturation levels of -6 dBm (MM) and -3 dBm (SM) define the maximum input power at which the device still operates correctly.

Compatibility and Accessories
The media converter is available with various fiber optic connectors, with the model PTC-101-M-ST-HV specifically equipped with ST connector. Support for multimode and singlemode fibers allows use in existing or newly constructed fiber networks. The power supply is designed for use in high-voltage environments, making it particularly suitable for applications in power supply systems. Compliance with IEC 61850-3 ensures adherence to requirements for power plants.

Mounting and Installation
Mounting is done via the DIN rail, enabling quick and secure installation in the enclosure. Dimensions of 152.15 × 126.46 × 66.65 mm and a weight of 785 g (device) are designed for use in standard enclosures. Installation requires no additional tools, as connections are made via the integrated power supply and standard network interfaces. The included quick installation guide supports the user during setup.

Operational Advantages
Operation over a wide voltage range (100–240 VAC/VDC) increases installation flexibility. The high operating temperature range of -40 to 85 °C enables use in extreme environments. The integrated power supply and robust construction reduce maintenance costs and increase system availability. The MTBF of 4,660,534 hours (according to Telcordia SR332) underscores the high reliability of the device. Certifications according to EN/UL 62368-1, IEC 61000-4-2 to -4-11, and IEC 60068-2-1/-2-14/-2-3 guarantee safety and electromagnetic compatibility.

Scope of Delivery
The scope of delivery includes 1 x media converter of the PTC-101 series, 1 x quick installation guide, and 1 x warranty card.
