Abstract

An optical fiber attenuation sensor that includes a first protrusion movable between a first position and a second position, a second protrusion movable between a third position to a fourth position, and an elastic object coupled to the first protrusion that causes the first protrusion to move from the first position to the second position. When the first protrusion moves from the first position to the second position, the second protrusion moves from the third position to the fourth position. The second protrusion is configured and positioned to cause an event in a signal in an optical fiber when the second protrusion moves from the third position to the fourth position.
