Abstract: A clamp for clamping optical fiber to a tube. The clamp has a body portion coupled at one end to a first arm and at an opposing end to a second arm, and 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. At least one of the body portion, the first arm and the second arm has 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.

Abstract: Described are methods and systems using optical fiber interferometry to sense interference causing events in a region of interest and differentiate between a strain event and a thermal event. Other methods and systems relate to the use of optical fiber interferometry for determining temperature offset in a region of interest and using the determined temperature offset for determining temperature in the region of interest.
