| Abstract: | This paper analyses the principle of the Brillouin back-scattering effect based on sensing and the positioning principle based on OTDR(Optical Time-Domain Reflectometry).A new type of optical fiber named carbon hermetically coated optical fiber which is used in the temperature and strain measurement of the complex submarine system is discussed.Meanwhile,the anti-corrosion and anti-fatigue properties and other applications of carbon hermetically coated optical fibers are analysed,and the installation method ... |
