ABSTRACT:
An optical fiber continuous measurement system continually measures at least one optical property along a length of optical fiber. The system includes a rotatable body onto which a reflector is secured. The reflector is optically coupled to an end of the optical fiber, thereby allowing light propagating from the optical fiber to the reflector to be reflected back along the length of the optical fiber toward a measuring device. The property to be measured is acquired as the fiber is wound from one rotatable body to the other. The system is particularly suited for measuring attenuation, including macrobend loss in which case a localized bending mechanism is employed, along the length of the fiber.
