The application discloses a time division multiplexing system and method based on a microstructure optical fiber EFPI hydrophone, and the system comprises a tunable laser, a continuous light with continuously switched wavelengths is outputted; an acousto-optic modulator, the continuous light is chopped into time division multiplexing pulse light; a time division multiplexing component, comprising a time division multiplexing sensing array based on the microstructure optical fiber EFPI hydrophone, time division multiplexing interference pulse light with sensing information is outputted; and an optical receiving unit, the time division multiplexing interference pulse light is received and demodulated. The microstructure optical fiber EFPI sensor has the advantages of simple and compact structure, high sensitivity, small volume and large-scale manufacturing, and is a new way to realize miniaturization of the optical fiber hydrophone. The application is applied to the field of the optical fiber hydrophone, when the tunable laser emits a series of continuously switched light at a fixed step, the signal light of each wavelength can generate an interference signal through a time division multiplexing array element, and large-scale time division multiplexing of the optical fiber EFPI hydrophone based on the microstructure is realized.
