Abstract
The invention discloses a high sensitivity vibration detection optical cable which includes a sensing optical fiber. A metal tube is arranged on the outer side of the sensing optical fiber, first vibration conductive filing materials are arranged between the sensing optical fiber and the metal tube, an aramid fiber sleeve is arranged on the outer side of the metal tube, and second vibration conductive filing materials are arranged between the metal tube and the aramid fiber sleeve. A metal mesh grid is arranged on the outer side of the aramid fiber sleeve. An optical cable outer sleeve is arranged on the outer side of the metal mesh grid. Third vibration conductive filing materials are arranged between the metal mesh grid and the optical outer sleeve. The high sensitivity vibration detection optical cable is fast in temperature response speed and good in water resistance performance. Multi layers of the vibration conductive filling materials integrate various components in the interior, enable the physical vibration received by the optical cable outer sleeve to be quickly transmitted to the internal sensing optical fiber, and solve the problem that the vibration detection is not sensitive.
