Claim:
1. An optical fiber cable that is installed in or along a measurement object so as to be deformed along with the measurement object and is for measuring distributions of pressure, temperature, and strain of the measurement object by using a Brillouin frequency shift and a Rayleigh frequency shift of light entered into and scattered in the optical fiber cable, the optical fiber cable comprising: an optical fiber core for measuring pressure of the measurement object; and a multilayer armor cable for measuring temperature of the measurement object, wherein an annular clearance space is formed between the optical fiber core and the multilayer armor cable, and fixing members are arranged in the clearance space at intervals in the axial direction of the optical fiber cable to fix the optical fiber core and the multilayer armor cable.
