The utility model provides a railway facility settlement prediction device based on an optical fiber sensing technology, and mainly relates to the technical field of settlement monitoring devices. The railway facility settlement prediction device based on the optical fiber sensing technology comprises an optical fiber analyzer and an optical cable connected with the optical fiber analyzer through a connector, a plurality of connecting sleeves are fixedly installed outside the optical cable, and a binding belt is fixedly installed on one side of the periphery of each connecting sleeve. A limiting device capable of locking the binding belt is arranged at the bottom of the periphery of the connecting sleeve. The device has the advantages that the device monitors the optical fiber buried in the tunnel in real time, whether the optical fiber is bent due to tunnel settlement or not can be judged according to the change of the refractive index of light in the optical fiber, and the device is simple in structure and
