An optical fiber containing one or more random modulations capable of reflecting one or more random wavelengths of light passing through the optical fiber is provided. Each modulation is a section of the optical fiber in which the refractive index has been modified or a section of random refractive index optical fiber that has been spliced into the optical fiber. The optical fiber is produced by modifying the refractive index of at least one portion of the optical fiber through photo-etching, photo-bleaching, ultraviolet radiation exposure or splicing. The optical fiber containing the random modulation is used to measure one or more engineering parameters by locating the section or portion of the optical fiber containing the random modulation in an area where the engineering parameter is to be measured and measuring the engineering parameter using optical frequency domain reflectometry.
An optical fiber containing at least one modulation having a random refractive index, wherein the modulation is capable of reflecting one or more random wavelengths of light passing through the optical fiber.
A method for making an optical fiber having at least one modulation comprising the steps of photo-etching the fiber by passing an ultraviolet radiation through a medium capable of producing a random modulation in the ultraviolet radiation and exposing the radiation on a section of the optical fiber.
