### 4. Functionality

The TRP-C41S functions as a transparent media converter between copper-based Ethernet and fiber optic networks. It receives electrical Ethernet signals through the RJ-45 port and converts them into optical signals transmitted via the SC fiber connector. Conversely, it converts incoming optical signals back into electrical Ethernet signals for copper-based devices.

Use Cases and Applications:
- Industrial Automation: Connects remote PLCs, sensors, and controllers across factory floors or between buildings.
- Surveillance Systems: Extends IP camera connections over long distances without signal degradation.
- Campus and Building Networks: Links network segments across large facilities or between separate structures.
- Telecommunications and ISP Infrastructure: Provides reliable last-mile fiber connectivity.
- Transportation and Utilities: Suitable for railway, power grid, and traffic control systems requiring EMI-resistant communication.

Compatibility:
- Compatible with standard Ethernet switches, routers, and network interface cards (NICs).
- Supports both straight-through and crossover Ethernet cables due to auto MDI/MDI-X functionality.
- Works with single-mode fiber optic cables (9/125 µm) using SC connectors.
