Abstract
An apparatus includes an enclosure having one or more apertures for receiving therethrough optical fiber, and one or more actuators sealed within the enclosure for generating one or more interference signals for interfering with optical fiber within the enclosure such that an optical path length of the optical fiber is altered. A method for verifying an event detection system includes interrogating optical fiber positioned alongside a conduit by sending one or more light pulses along the optical fiber and receiving reflections of the one or more light pulses. The method further includes using an event verification device housed within an enclosure through which passes the optical fiber to generate one or more interference signals for interfering with the optical fiber such that an optical path length of the optical fiber is altered.
