摘要

optical fiber, fiber optic cable, distributed acoustic fiber optic sensor, use of an optical fiber, distributed fiber sensor, and an optical fiber cable. better performing fiber optic cables are disclosed for use in distributed detection, for example in distributed acoustic sensors. In one embodiment, a fiber optic cable (210) comprises a core (208) and sheath (206) disposed within a damping material (202) and encased by a jacket (204) and arranged such that the core is displaced. from the center of the cable. By shifting the core from the center of the jacket, any bending effect on the core can be maximized compared to when the core is located at the center of the cable.
