Cut Fiber
When the fiber, for any reason, is broken between two
sensors in a series, the sensors that are after the fault
may disappear from the optical spectrum and may not be
detected.
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.

trum for these three presented cases.
