### 4. Functionality

The TRP-C41 functions as a transparent media converter between copper-based Ethernet and fiber optic networks. It enables Ethernet devices to communicate over long distances by converting electrical Ethernet signals into optical signals and vice versa.

Operation Principle:
- The RJ-45 port connects to standard Ethernet equipment such as switches, routers, or PCs.
- The SC fiber port connects to a single-mode fiber link, transmitting data over distances up to 20 km.
- The device automatically negotiates speed and duplex settings, ensuring optimal performance without manual configuration.
- Built-in Link Fault Pass-Through (LFP) and Far-End Fault (FEF) mechanisms maintain network reliability by detecting and propagating link failures across both media types.

Typical Use Cases:
- Extending Ethernet networks across large campuses, industrial sites, or between buildings.
- Providing noise-immune communication in electrically noisy environments such as factories or substations.
- Integrating remote IP cameras, sensors, or controllers into centralized monitoring systems.
- Bridging network segments where copper cabling is impractical due to distance or EMI concerns.

Compatibility:
- Compatible with all standard Ethernet devices supporting 10/100Base-TX.
- Interoperable with other IEEE 802.3u-compliant fiber networking equipment.
- Supports both straight-through and crossover Ethernet cables due to auto MDI/MDI-X functionality.
