摘要： Various embodiments provide a clamp for clamping optical fiber to a tube, the clamp comprising a body portion coupled at one end to a first arm and at an opposing end to a second arm, the clamp having a resilient portion to permit the clamp to elastically deform from a closed state in which the clamp is fastened around the tube to an open state in which the clamp is radially moveable off the tube, wherein application of a force separating the first and second arms biases the resilient portion and transitions the clamp from the closed state to the open state, and wherein the resilient portion returns the clamp from the open state to the closed state when the force is removed, at least one of the body portion, the first arm and the second arm having a clamping surface to clamp a portion of the optical fiber against the tube when the clamp is fastened around the tube, and a clamping mechanism operable to extend at least part of the clamping surface towards the tube when the clamp is secured to the tube to increase a clamping force applied by the clamping surface. Various other embodiments provide a method of clamping optical fiber to a tube.

摘要： A method for non-intrusive pipeline testing involves constructing the pipeline at a construction location that is above ground, affixing an optical fiber along a surface of a length of the pipeline that is at the construction location, measuring dynamic strain experienced by the length of the pipeline by performing optical interferometry using the optical fiber, and moving the length of the pipeline from the construction location to a different installation location. The optical fiber includes at least one pair of fiber Bragg gratings ("FBGs") tuned to reflect substantially identical wavelengths with a segment of the optical fiber extending between the FBGs.
