The IMC-101-S-SC-80-T from Moxa is an industrial media converter that converts Ethernet connections over copper cables (10/100BaseT(X)) into fiber optic transmissions (100BaseFX). It is specifically designed for applications requiring high availability and mechanical robustness, such as in automation technology, process industry, or marine environments. The device enables the connection of Ethernet networks over long distances with high signal integrity and is certified for use in hazardous areas.

Applications
This media converter is suitable for industrial networks where reliable data transmission over long distances is required. It is commonly used in installations exposed to high mechanical stress, vibrations, or electromagnetic interference. Certification to Class 1 Div. 2/Zone 2 and IECEx makes it suitable for areas with explosion risks. DNV certification ensures suitability for marine applications.

Functions and Equipment in Detail
The converter features an RJ45 connector for Ethernet connection and an SC connector for fiber optic connection. It supports single-mode connections with a range of up to 80 km at a wavelength of 1550 nm. Optical characteristics include a link budget of 29 dB for single-mode and an RX range of -3 to -34 dBm, ensuring high sensitivity and stability in signal transmission. An integrated relay signals power failure or port disconnection, which is important for monitoring critical installations. The Link Fault Pass-Through (LFPT) function allows immediate detection of a connection interruption at the remote device.

Technology Explained Simply
The conversion of Ethernet signals to fiber optic is achieved via an optical interface that converts electrical signals into light pulses. The use of single-mode fiber enables transmission over long distances with minimal signal attenuation. Power supply is via a DC input of 12 to 45 VDC, with redundant inputs available to increase availability. Magnetic isolation of 1.5 kV protects against electrical interference. The operating temperature of the -T model ranges from -40 to 75 °C, enabling use in extreme environments.

Compatibility and Accessories
The converter is compatible with standard network devices supporting 10/100BaseT(X) and 100BaseFX. The use of SC connectors allows integration into existing fiber optic infrastructures. Certifications according to EN 55032/24, FCC Part 15B, and CISPR 32 ensure electromagnetic compatibility. Environmental tests according to IEC 60068-2-1 to -2-6 ensure robustness against temperature changes, humidity, and vibrations.

Mounting and Installation
The device is mounted on a DIN rail, enabling easy integration into existing enclosures. Power supply is via screw terminals (terminal block), ensuring a secure and reliable connection. Mounting requires no special tools, and connections are clearly labeled.

Operational Advantages
The high MTBF of 401,000 hours (according to MIL-HDBK-217F) demonstrates the device's high reliability. The integrated monitoring function with relay and LFPT enables rapid fault detection. The wide operating voltage range of 12 to 45 VDC and redundant power supply increase availability. Certifications for hazardous areas and marine applications significantly expand the range of applications.
