An all-fiber accelerometer with temperature self-compensation based on Fabry-Pérot interferometer (FPI) and simple-supported beam is proposed, where the two reflectors are the joint face between single mode fiber (SMF) and hollow core fiber and the end face of the micro fiber used as vibration beam, respectively. The temperature effect could be compensated by choosing proper material for the beam because it is movable in the FPI cavity. When the beam length composed of SMF is 6 cm and the mass block is ~1.3218×10-7 Kg, the acceleration sensitivity is ~0.35 V/g and the temperature sensitivity is less than 1pm/°C;.
