Why is it essential to use a calibrated light source and optical power meter when conducting insertion loss measurements?

It is essential to use a calibrated light source and optical power meter when conducting insertion loss measurements to ensure accurate and reliable results. Insertion loss is the amount of optical power lost as a signal travels through a component or a section of fiber. A calibrated light source provides a stable and known optical power at a specific wavelength. Calibration ensures that the light source is emitting the power level indicated on its display, minimizing errors in the measurement. A calibrated optical power meter is used to measure the optical power at the receiving end of the component or fiber. Cal....
