### 4. Functionality

The IMC-P111FX-SS-SC-M12-LV functions as a media converter bridging copper Ethernet and fiber optic networks. It converts electrical Ethernet signals (10/100Base-TX) to optical signals (100Base-FX), enabling long-distance data transmission up to 30 km over single-mode fiber.

Operational Features:
- Auto-negotiation: Automatically detects link speed (10/100 Mbps) and duplex mode.
- Auto MDI/MDI-X: Eliminates the need for crossover cables.
- LFP (Link Fault Pass-through): When one link fails, the converter disables the corresponding link on the opposite side, allowing network management systems to detect and respond to failures immediately.
- Full/Half Duplex Support: Configurable via DIP-switch for both Ethernet and fiber ports.
- Relay Alarm Output: Provides external signaling for power failure or link fault events.

Use Cases:
- Power substations and smart grid communication (IEC 61850-3 environments)
- Railway and rolling stock Ethernet backbone (EN50155 compliance)
- Industrial automation and process control networks
- Remote monitoring and SCADA systems
- Long-distance Ethernet extension over fiber

Compatibility:
- Compatible with standard Ethernet devices (switches, PLCs, RTUs, routers)
- Supports both multi-mode and single-mode fiber configurations (depending on model variant)
