Abstract
An optical fiber has at least one optical sensor with at least two interconnects with associated insertion losses. A first optical sensing interrogator is coupled through an interconnect to one end of the optical fiber with the sensors, and a second optical sensing interrogator is coupled through an interconnect to an opposite end of the optical fiber on an opposite side of the sensors. The first optical sensing interrogator and the second optical sensing interrogator determine one or more fiber insertion losses associated with the optical path in between the sensors and the interrogators, and between sensors if there are two or more sensors, without foreknowledge of the sensor reflectivity.
