Disclosed is an optical fiber overheat detection testing apparatus including an optical fiber having a first end and a second end, the optical fiber having a predetermined length associated with a predetermined attenuation based on an overheat detection instrument loop. The apparatus includes a first interrupt disposed equidistant between the first end and the second end defining a first half of the optical fiber and a second half of the optical fiber, the first half and the second half having equal length, the first interrupt having a first actuator operable by a first electric current to attenuate light wave traversal of the optical fiber. The apparatus includes a second interrupt disposed on the first half and spaced from the first end at least six tenths of a meter, the second interrupt having a second actuator operable by a second electric current to attenuate light wave traversal of the optical fiber.

Overheat testing apparatus for optical fiber

Disclosed is an optical fiber overheat detection testing apparatus. The apparatus includes an optical fiber having a first end and a second end, the optical fiber having a predetermined length associated with a predetermined attenuation based on an overheat detection instrument loop. The apparatus includes a first fiber Bragg grating disposed on the optical fiber having a first wavelength spectrum based on a first temperature detection apparatus. The apparatus includes a second fiber Bragg grating disposed on the optical fiber having a second wavelength spectrum based on at least one of a plurality of overheat detection apparatuses.
