Moxa IMC-P101-S-ST content_copy

The Moxa IMC-P101-S-ST is an industrial media converter that enables conversion of Ethernet signals in 10/100BaseT(X) format to fiber optic signals in the 100BaseFX standard. The device is specifically designed for use in industrial networks where reliable data transmission over long distances and simultaneous power supply via PoE (Power over Ethernet) are required. The converter features an ST connector for single-mode fibers and supports a maximum range of up to 40 km at a wavelength of 1310 nm. The integrated PoE function allows power supply to end devices such as IP cameras or access points via the network cable, delivering up to 30 W of power. The PoE technology complies with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards, with PoE+ support available from hardware revision 1.1.0.

Applications

The IMC-P101-S-ST is suitable for industrial applications requiring stable and long-range data transmission, such as in manufacturing automation, the energy sector, or transportation. The use of single-mode fibers enables transmission over distances up to 40 km, making it particularly suitable for applications in large factories, between sites, or in infrastructure. The robust construction and operating temperature range of -40 to 75 °C (for -T models) make the device suitable for extreme environmental conditions, such as those found in outdoor environments or in demanding production environments.

Functions and Features in Detail

The device features an RJ45 interface for Ethernet connection and an ST connector for fiber optic connectivity. Automatic MDI/MDI-X detection ensures the connection can be established without additional cable configuration. Data transmission occurs in Store-and-Forward mode or Pass-Through mode, optimizing network performance. A relay contact signals an alarm in case of power failure, which is beneficial for network monitoring and maintenance. Power supply is via a DC input with a voltage of 12–57 VDC (from revision 1.1.0) and supports redundant inputs to increase availability.

Technology Explained Simply

The conversion of Ethernet to fiber optic involves transforming electrical signals into optical signals, which are transmitted over the fiber optic cable. The ST connector is a standard for fiber optic connections and provides a secure and mechanically stable connection. Single-mode fiber has a smaller core and enables higher bandwidth and longer transmission distances compared to multi-mode fibers. The wavelength of 1310 nm is typical for single-mode transmissions and offers a good balance between attenuation and bandwidth. The recommendation to use an attenuator with single-mode fibers serves to optimize signal quality, especially in short connections, to avoid overloading the receiver.

Compatibility and Accessories

The converter is compatible with standard Ethernet networks and supports connections to devices using PoE. The devices can be combined with other models from the IMC-P101-S series to create a homogeneous network. The PoE function is compatible with devices supporting IEEE 802.3af or IEEE 802.3at standards.

Mounting and Installation

Mounting is done on a DIN rail, enabling flexible and secure installation in enclosures or rack systems. Power supply is via an external DC power supply or redundant power supply, with the devices featuring overcurrent protection.

Operational Advantages

Operation of the IMC-P101-S-ST is characterized by high reliability and long service life. The MTBF (Mean Time Between Failures) is 2,892,595 hours according to Telcordia SR332, indicating high availability and low maintenance frequency. The robust metal housing construction protects the device from mechanical influences, and certifications according to UL 508, EN 62368-1, EN 55032/35, CISPR 32, FCC Part 15B Class A, as well as IEC 61000-4-2/3/4/5/6/8, guarantee safety and EMC compliance. The operating temperature range of -40 to 75 °C allows use in a wide variety of environments, including extreme climatic conditions.
