The IMC-P101-M-ST-T from Moxa is an industrial PoE Ethernet-to-fiber media converter, specifically developed for use in demanding environments. It serves to convert signals between 10/100BaseT(X) Ethernet networks via RJ45 connection and 100BaseFX fiber connections via ST connector. The integrated magnetic isolation of 1.5 kV protects connected devices from voltage surges. The device is designed for use in industrial networks where high reliability, mechanical robustness, and operation under extreme environmental conditions are required.

Applications
This converter is suitable for industrial applications requiring stable, long-distance data transmission over fiber, such as in manufacturing automation, power supply, or transportation. Connecting Ethernet networks with fiber enables high bandwidth and immunity to electromagnetic interference. The multi-mode fiber with ST connector supports transmission distances up to 4 km, using cable type OM1 (50/125 µm) and wavelength 1300 nm. The operating temperature range of -40 to 75 °C makes the device suitable for outdoor or climatically challenging environments.

Functions and Equipment in Detail
The IMC-P101-M-ST-T features an RJ45 port with PoE function (PSE) and supports Auto-Negotiation as well as Auto-MDI/MDI-X, enabling automatic adaptation to network partners. The fiber side provides an ST connector for multi-mode fibers. The devices are equipped with a relay output that triggers an alarm in case of power failure. Network functions include support for IEEE 802.3, 802.3u, and 802.3x standards. Power supply is provided via redundant DC inputs, ensuring higher availability. The power supply voltage is 12 to 57 VDC from hardware revision 1.1.0.

Technology Explained Simply
The conversion of Ethernet signals to fiber signals is performed by an integrated transceiver. The Store-and-Forward function allows complete reception and inspection of data packets before forwarding, enhancing network security. The Pass-Through option enables direct forwarding without buffering. Optical characteristics are designed for multi-mode fibers: the TX range is -10 to -20 dBm, the RX range is -3 to -32 dBm, achieving a link budget of 12 dB. The dispersion penalty is 3 dB. The integrated PoE power supply reduces the number of required cables and simplifies installation, especially for decentralized end devices.

Compatibility and Accessories
The converter is compatible with standard 10/100BaseT(X) Ethernet networks and multi-mode fiber cables of type OM1 with 50/125 µm. Connection is made via an ST connector. The devices can be integrated into existing industrial networks that use PoE end devices. The use of attenuators is recommended for single-mode applications but is not required for the multi-mode model.

Mounting and Installation
The device is mounted on a DIN rail, enabling flexible and secure installation in enclosures. The robust metal housing protects against mechanical impacts. Installation involves connecting to the Ethernet network via RJ45 and to the fiber cable via the ST connector. Power supply is provided through the redundant DC input interface. The quick installation guide included in the package supports setup.

Operational Advantages
The IMC-P101-M-ST-T offers high operational reliability through redundant power supply, extended temperature range, and integrated interference protection measures. The PoE function reduces installation costs and simplifies maintenance. The MTBF (Mean Time Between Failures) is 2,892,595 hours according to Telcordia SR332, highlighting high reliability. Certifications according to UL 508, EN 62368-1, EN 55032/35, CISPR 32, and FCC Part 15B Class A ensure safety and EMC compliance. The devices are designed for use in industrial environments with high requirements for interference resistance and environmental durability.
