MEASURING EXAMPLES
There may also be the case that the fiber is cut, but not completely spread apart (e.g. the
fiber is damaged in an area covered with glue). This will cause a Fabry-Pérot effect – the
light will suffer multiple reflections inside the cavity creating sinusoidal background
reflection.

sented cases.
