Universal distributed sensing optical cable

The utility model relates to a universal distributed sensing optical cable capable of carrying out real-time monitoring on fence type and buried type security systems. The universal distributed sensing optical cable comprises a composite loose sleeve in which an aramid fiber yarn and a tight tube sensing optical fiber are laid, and an outer sheath is wrapped on the outside of the composite loose sleeve. The beneficial effects of the utility model are that 1.a tight tube sensing optical fiber is employed to substitute the conventional loose sleeve sensing optical fiber, not only protecting the optical fiber effectively, but also enhancing the sensibility of the optical fiber about the effects, such as pressure, strain, vibration, etc.; 2.the aramid fiber yarn can not only protect the tight tube sensing optical fiber, but also not affect the free vibration and deformation of the tight tube sensing optical fiber at the same time, fully guaranteeing the maximum sensitivity of the sensing optical fiber; 3. the uni
