Abstract:
(EN) In the present invention, a plurality of through-holes are formed in a metallic cylindrical pipe that composes the outer circumferential part of a fiber-in-metallic-tube that is provided to an optical fiber cable and has an optical fiber provided therein that serves as a pressure sensor for measuring a distributed pressure, temperature, and strain system, and pressure blocking parts are provided so as to be distributed in the axial direction.
