How to Use This Tool
This calculator helps you design and analyze fiber optic links by calculating total attenuation and power budget.
Step-by-Step Guide
1. Configure Basic Parameters
Select the operating wavelength and fiber type. Enter the total link distance in kilometers.
2. Add Link Components
- Connectors: 0.3-0.5 dB typical loss
- Fusion splices: 0.05-0.1 dB typical loss
- Mechanical splices: 0.1-0.3 dB typical loss
- WDM components: 0.5-3.0 dB typical loss
- Patch panels: 0.5-1.0 dB typical loss
3. Enter Power Levels
Enter transmitter output power and receiver sensitivity from transceiver datasheets.
4. Set Design Margin
Typical margin values range from 3-6 dB depending on application criticality.
Pro Tips
- Use higher margins (5-6 dB) for critical links
- Verify component losses with manufacturer specs
- Consider repair splice allocations for long-haul links
- Use Monte Carlo analysis for statistical reliability
