The Moxa IMC-P101-M-ST is an industrial media converter that enables the conversion of 10/100BaseT(X) Ethernet signals via RJ45 connection into 100BaseFX fiber optic signals. The device is specifically designed for use in demanding industrial environments and offers PoE and PoE+ functionality in accordance with IEEE 802.3af and IEEE 802.3at standards. The integrated power supply over the network cable (PoE) allows connected end devices to be powered with up to 30 W, eliminating the need for separate power lines. The robust metal housing design and support for redundant DC power inputs ensure high operational reliability. The model is designed for use in an extended temperature range of -40 °C to 75 °C, making it suitable for applications in harsh environments such as production halls, outdoor areas, or climatically extreme regions.

Applications

The IMC-P101-M-ST is used in industrial networks where reliable and long-lasting data transmission over long distances is required. Typical application scenarios include networking machines in manufacturing, connecting surveillance cameras, sensors, or other PoE-enabled devices via fiber optic. The use of fiber optic enables high bandwidth and immunity to electromagnetic interference, which is advantageous in industrial environments with high EMC risk. DIN rail mounting facilitates integration into existing enclosures.

Functions and Equipment in Detail

The device features an RJ45 port for 10/100BaseT(X) Ethernet with integrated PoE functionality. Auto-Negotiation and Auto-MDI/MDI-X functions ensure automatic adaptation to connected devices, eliminating the need for manual configuration. The fiber optic connection is implemented as an ST connector for multi-mode fiber, enabling a reach of up to 4–5 km. Optical characteristics include a typical wavelength of 1300 nm, a transmit power (TX) of -10 to -20 dBm, and a receive sensitivity (RX) of -3 to -32 dBm. The link budget is 12 dB, including a dispersion penalty of 3 dB. The integrated magnetic isolation of 1.5 kV protects against electrical interference and potential differences.

Technology Explained Simply

The media converter acts as a bridge between copper cables (Ethernet) and fiber optic cables. It converts the electrical signals of the Ethernet network into optical signals transmitted over fiber optic. This enables longer reach and higher interference resistance compared to pure copper connections. The PoE function powers connected devices over the same cable that carries data, simplifying installation. Redundant power supply via two DC inputs increases availability, as a second input takes over in case of power failure. The relay-based alarm function allows integration into monitoring systems to trigger a response in case of faults or outages.

Compatibility and Accessories

The IMC-P101-M-ST is compatible with standard 10/100BaseT(X) Ethernet devices and supports the use of multi-mode fiber optic cables with ST connectors. Connection to other media converters or switches is made via the RJ45 interface. For integration into existing networks, support for Store-and-Forward and Pass-Through modes is relevant, with the Pass-Through mode offering lower latency. The use of attenuators is recommended for single-mode variants but is not required for this model, as it is designed for multi-mode.

Mounting and Installation

Mounting is done on a DIN rail, enabling easy installation in enclosures. Power supply is via DC inputs with a voltage range of 12–57 VDC (from Rev. 1.1.0) or 46–57 VDC (Rev. 1.0.1 and earlier). Power consumption is 360 mA at 12–57 VDC (from Rev. 1.1.0) or 430 mA at 46–57 VDC (Rev. 1.0.1). The devices are designed for use in harsh environments, with operating temperature ranging from -40 °C to 75 °C and humidity from 5 to 95 % (non-condensing).

Operational Advantages

Operation of the IMC-P101-M-ST is characterized by high reliability and low maintenance requirements. The MTBF (Mean Time Between Failures) is 2,892,595 hours according to Telcordia SR332, indicating a very long service life and operational safety. The integrated PoE function reduces the number of required cables and simplifies installation. The robust metal construction and certifications according to UL 508, EN 62368-1, as well as EMC standards such as EN 55032/35 and FCC Part 15B Class A, guarantee safe operation in industrial environments. Immunity to interference according to IEC 61000-4-2 to -4-8 and vibration test standard IEC 60068-2-6 ensure reliable operation under mechanical and electrical stress.
