How to Use This Calculator
- Enter the Input Power (total optical power entering the fiber) in milliwatts (mW).
- Enter the Output Power (optical power successfully coupled into the fiber) in milliwatts (mW).
- Select the appropriate Fiber Type from the dropdown menu.
- Click the Calculate button to compute the coupling efficiency and efficiency class.
- The calculator will display the efficiency percentage and classify it as Excellent, Good, Fair, or Poor based on industry standards.
Understanding Fiber Coupling Efficiency
Fiber coupling efficiency is a critical parameter in fiber optic systems that measures how effectively light is transferred from one medium (source) to another (fiber). It represents the percentage of optical power that successfully enters the fiber compared to the total input power.
The formula used is:
Efficiency (%) = (Output Power / Input Power) × 100%
Interpreting Results
- Excellent (90%+): Indicates minimal power loss and optimal coupling conditions.
- Good (80-89%): Shows acceptable power loss with minor coupling issues.
- Fair (70-79%): Indicates significant power loss requiring optimization.
- Poor (<70%): Shows severe coupling problems that need immediate attention.
