Special challenges included extreme weather conditions, wide temperature variations and the need for simple maintenance despite remote locations.
The solution for extreme environments
Specialised DIN-rail fibre optic boxes were installed in each wind turbine, rated for extended temperature ranges (0°C to +60°C). The boxes were equipped with E2000 connectors, particularly suitable for this environment thanks to their automatic dust cap.
Technical specification:
- 8 E2000 ports per turbine
- Single-mode fibre for distances up to 10km
- Redundant ring topology for high availability

The result
Operational results:
- Uninterrupted data capture with system availability of 99.98%
- Improved remote maintenance capability through increased bandwidth
- Reduced on-site visits through reliable components
- Simplified troubleshooting through modular design
Technical requirements and best practices
These and other real-world examples yield several overarching best practices for deploying DIN-rail fibre optic boxes:
1. Correct sizing
Selecting the right DIN-rail fibre optic boxes depends on several factors:
Sizing criteria:
- Number of required fibre optic connections (typically 4–24 ports)
- Available cabinet space (standard 7TE width)
- Connector type (LC, SC, E2000)
- Need for splicing within the box
Our experience with fibre optic solutions for system integrators shows that a capacity reserve of approximately 20–30% should be planned for future expansion.
2. Cable management
Well-planned cable management is essential for the longevity of DIN-rail fibre optic boxes installation:
Management principles:
- Maintain minimum bend radii of at least 30mm
- Consistently use strain relief
- Organise excess lengths systematically
- Clearly label all connections per DIN standards
3. Connector selection
Different connector types are recommended for DIN-rail fibre optic boxes depending on deployment environment:
Connector matrix:
- E2000 connectors: Highest requirements and dusty environments
- LC duplex: Space-limited applications and high port density
- SC simplex: Cost-sensitive applications with standard requirements
For industrial applications with vibration, dust or moisture, E2000 connectors with their automatic dust cap and secure locking have proven particularly effective.
