The invention relates to a novel large-wrapping sensing fiber and a fiber sensing ring thereof. The fiber is formed by twisting a long beat length polarized photonic crystal fiber from beginning to end, and the minimum pitch of the fiber after twisting is between 0.2 and 2mm. A wrapping of the fiber is between 300-800[mu]m. The sensing ring comprises a quartz substrate layer, a sensing fiber, a quartz upper wrapping, an external protection skeleton and the like. The ultra-fast laser processing technology is used to perform overall shaping of the integrated sensing fiber. After the stress is released by annealing, the rough part is grinded. A central through hole is drilled, and is placed in the external protection skeleton for fixed packaging. The expansion coefficient of the quartz substrate layer is close to that of the fiber. After the sensing ring is packaged, influences of external temperature and vibration on the integrated fiber polarization are reduced, and the integrated fiber is effectively fixed and protected. The manufacturing precision is high, and the usage is convenient.
