Abstract
An optical fiber includes an integrated detector in the form of phosphors that emit light of a characteristic frequency or wavelength in response to leakage, through the fiber cladding, of light having an interrogation wavelength λ. Stimulation of phosphor emission by the interrogation light is indicative of aging or wear on the layers surrounding the cladding, and therefore can be used to assess the risk of imminent breakage of the fiber.
