A system and method for measuring stress exerted on an optical fiber (12) including providing an optical fiber (12) that includes a fiber optic sensor (14), and exposing the optical fiber (12) and the fiber optic sensor (14) to various stresses associated with the process by moving the optical fiber (12) and the fiber optic sensor (14) through the process to be measured. The system and method further includes transmitting a source light (36) through the optical fiber as the optical fiber and the fiber optic sensor are exposed to various stresses, receiving a return light signal (44, 46) from the fiber optic sensor as the optical fiber and the fiber optic sensor are exposed to various stresses, and comparing the source light signal (44) to the return light signal (46) for determining the stress exerted on the optical fiber.
