<p>A system for monitoring a plurality of components (205a, 205b) distributed in different space locations, the system comprising: at least one optical fiber path (215; 415', 415"); an optical radiation source (230) adapted to inject an optical radiation (I; I', I") into the at least one optical fiber path (215; 415', 415"); at least one first and at least one second optical branches branching from the at least one optical fiber path (215; 415', 415") and adapted to spill respective portions (I1a, I2a, I1b, I2b) of the optical radiation (I; I', I"), the first and second optical branches being adapted to be operatively associated with a respective component (205a, 205b) to be monitored. The first optical branch comprises a first optical reflector (233a, 233b) and is adapted to reflect the spilled optical radiation portion (I1a, I1b) unless the respective component (205a, 205b) at least partially breaks; the second optical branch comprises at least one passive optical attenuator (235a, 235b) adapted to be operatively coupled to the respective component (205a, 205b) to be monitored, and having an attenuation capable of changing in response to a change in operating conditions of the respective monitored component (205a, 205b) when operatively coupled thereto, and a second optical reflector (240a, 240b). An optical receiver (250) is provided, adapted to detect back-reflected optical radiation (I1ar, I2ar, I1br, I2br) reflected by the first and second optical branches. The monitoring system is adapted to recognize a position of a component of the plurality of components (205a, 205b) based on a characteristic of the back-reflected optical radiation.</p> |
