The PTC-101-M-LC-HV media converter from Moxa is an industrial-grade device for converting Ethernet signals (10/100BaseT(X)) into fiber optic transmission (100BaseFX). It is specifically designed for demanding environments such as substations or process automation systems and meets the requirements of the standard IEC 61850-3, which applies to reliability and stability in critical energy installations. The device enables secure and standard-compliant communication over long distances, with the fiber optic connection largely eliminating interference and electromagnetic disturbances.

Applications

The PTC-101-M-LC-HV is suitable for industrial networks where high availability and interference resistance are required. Typical application scenarios include power supply networks, industrial automation systems, and installations connected over long distances. Support for 100BaseFX enables the use of fiber optic cables, which offer higher bandwidth and longer transmission distances compared to copper cables. The Multi-Mode variant with LC connector is designed for distances up to 5 km, while the Single-Mode variant can cover up to 40 km (up to 80 km with specified cable).

Functions and Features in Detail

The device features an RJ45 port for Ethernet connection (10/100BaseT(X)) and a fiber optic port with LC connector. The interfaces support Auto-Negotiation and Auto-MDI/MDI-X, enabling automatic speed and cable type detection. The LFPT (Link Fault Pass-Through) function ensures that a network fault at the fiber optic port is also indicated at the Ethernet port, simplifying network troubleshooting. The integrated power supply is designed for operation with 100–240 VAC/VDC, allowing flexible installation at various power sources. The power supply is equipped with an integrated overcurrent protection.

Technology Explained Simply

Fiber optic transmission operates using light signals transmitted through fiber optic cables. In the PTC-101-M-LC-HV model, the wavelength of 1300 nm is used for Multi-Mode and 1310 nm for Single-Mode. The RX sensitivity of -32 dBm (Multi-Mode) and -34 dBm (Single-Mode) indicates the minimum received power the device can still process. The TX power (transmit power) is -10 to -20 dBm (Multi-Mode) and 0 to -5 dBm (Single-Mode). The link budget of 12 dB (Multi-Mode) and 29 dB (Single-Mode) specifies the maximum attenuation the signal can overcome in the cable without the connection being interrupted.

Compatibility and Accessories

The media converter is compatible with standard Ethernet networks and fiber optic cables with LC connectors. The use of Single-Mode cables enables longer transmission distances, while Multi-Mode cables are suitable for shorter distances. The devices are designed for industrial environments and meet the requirements of IEC 61850-3, ensuring high reliability in critical applications. The devices do not include additional accessories such as cables, adapters, or external power supplies.

Mounting and Installation

The device is mounted on a DIN rail, enabling standardized installation in enclosures. The housing is made of metal and designed for use in harsh environments. Dimensions are 152.15 x 126.46 x 66.65 mm, allowing it to fit into standard enclosure modules. Mounting is tool-free, as the DIN rail provides mechanical fixation.

Operational Advantages

The PTC-101-M-LC-HV offers high operational reliability due to the integrated power supply and support for redundant power sources (in LV models). The operating temperature range of -40 to 85 °C makes the device suitable for extreme environmental conditions. Certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class A, and IEC 60068 guarantee high electromagnetic compatibility and reliability. The MTBF (Mean Time Between Failures) is 4,660,534 hours according to Telcordia SR332, indicating very high lifespan and reliability. The warranty period is 5 years.
