• A sensor using bending sensitive fiber (BSF) was studied for real-time long-distance sensing of submersion. The structure of the submersion sensor effectively used the relationship between buoyant force and bending loss of the BSF. A three-dimensional finite-difference beam propagation method (3D FD-BPM) was used to select the bending dimension of the proposed submersion sensor. The operation of the submersion sensor utilizing the BSF was also investigated using 3D FD-BPM. As results of experiments, the submersion sensor fabricated showed a change of optical power from $-17$ to $-1$ dB at 1550 nm when the selected sensing region was submerged. In addition, the BSF was easily connected to a single mode fiber (SMF) by fusionsplicing. The BSF exhibited a $-1$ dB loss when connected to a SMF at both ends.
