This application relates to the field of fiber optic towed sonar arrays, specifically disclosing a fiber optic towed linear array, comprising: a watertight optical cable, a transmission optical fiber, a multi-core optical fiber, multiple hydrophone probes, a sleeve, and a first watertight connector. The first watertight connector is installed in conjunction with the sleeve, and a watertight optical cable is disposed within the first watertight connector. The watertight optical cable branches into a transmission optical fiber and a multi-core optical fiber on the side near the sleeve. The transmission optical fiber is connected to the hydrophone probe, and the multi-core optical fiber is spirally wound around the outer periphery of the hydrophone probe and housed within the sleeve. The solution provided in this application overcomes the shortcomings of existing all-fiber towed linear arrays, which have many optical devices and can only measure attitude information at points, realizing distributed measurement of the towed array attitude and improving reliability.
