The IMC-P101-S-ST-T from Moxa is an industrial media converter that converts Ethernet connections over copper cables (10/100BaseT(X)) into fiber optic connections (100BaseFX). It enables seamless integration of copper and fiber optic networks in industrial environments where high reliability and robust operating conditions are required. The device features Power-over-Ethernet (PoE) functionality, allowing connected end devices such as IP cameras or access points to be powered with up to 30 watts of electrical power over the network cable, eliminating the need for additional power supply lines. The PoE function is compatible with the IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards, with PoE+ support available from hardware revision 1.1.0 onwards.

Applications
This converter is specifically designed for use in demanding industrial networks, such as in manufacturing automation, power supply, transportation, or surveillance technology. It is suitable for applications requiring stable, long-distance data transmission over fiber optic cables, while simultaneously powering connected devices via PoE. Its robust construction and extended operating temperature range also make it suitable for outdoor installations or harsh environments.

Functions and Equipment in Detail
The device features an RJ45 interface for 10/100BaseT(X) and a 100BaseFX fiber optic interface with ST connector. The fiber optic interface supports both multimode and singlemode connections, with the IMC-P101-S-ST-T model specifically designed for singlemode fiber optic. The maximum transmission range is 40 km for singlemode at a wavelength of 1310 nm. For multimode fiber optic, the range is 4–5 km at 1300 nm. The link budget is 12 dB for multimode and 29 dB for singlemode, with the recommendation to use an attenuator for singlemode connections to avoid overloading the receiver. The dispersion penalty is 3 dB (multimode) and 1 dB (singlemode).

Technology Explained Simply
The converter operates in Store-and-Forward mode, where data packets are fully received, checked, and then forwarded, ensuring high data integrity. Alternatively, Pass-Through mode is available, where data packets are forwarded directly without intermediate storage, enabling lower latency. Power supply is provided via two redundant DC inputs, ensuring high availability. The input voltage is 12–57 VDC for hardware revisions from 1.1.0 onwards; for older versions (1.0.1), the range is 46–57 VDC. Power consumption is 360 mA at 12–57 VDC (newer HW) or 430 mA at 46–57 VDC (older HW). An integrated overcurrent protection safeguards the device against damage.

Compatibility and Accessories
The converter is designed for use with singlemode fiber optic cables with ST connectors. Compatibility with other fiber optic types (e.g., multimode) is not provided, as the model is specifically configured for singlemode. The PoE function enables powering of end devices supporting IEEE 802.3af or 802.3at standards. For connection to other devices or networks, compatible fiber optic cables and network equipment are required.

Mounting and Installation
The device is delivered in a metal housing and is designed for mounting on a DIN rail. Mounting is achieved using integrated fastening elements, enabling secure and stable installation in enclosures or control cabinets. Physical dimensions are 144.5 mm (width) × 122.3 mm (height) × 51.65 mm (depth). The product weight is 532 g, and the packaged weight is 701 g.

Operational Advantages
The IMC-P101-S-ST-T offers high operational reliability through redundant power supply, EMI immunity according to industrial standards (e.g., EN 55032/35, CISPR 32, FCC Part 15B), and high mechanical stability (vibration test according to IEC 60068-2-6). The operating temperature range for the -T variant is -40 to 75 °C, making it suitable for extreme environments. The MTBF (Mean Time Between Failures) is 2,892,595 hours according to Telcordia SR332, indicating high reliability over a long period. A relay output enables alarm signaling in case of power failure, which is beneficial for critical applications. Safety certifications include UL 508 and EN 62368-1, confirming compliance with international safety standards.
