PROBLEM TO BE SOLVED: To provide an optical cable for an FBG sensor temperature-corrected with high accuracy. SOLUTION: In this optical cable 1 for an FBG sensor, an FBG 44 for a sensor is written on an optical fiber 42 for a sensor laid along a measuring object used for detecting displacement of the measuring object. An optical fiber 2 for temperature correction is provided along the optical fiber 42. An FBG 3 for temperature correction used for temperature-correcting the FBG 44 is written on the optical fiber 2 at the same position as the the FBG 44. COPYRIGHT: (C)2006,JPO&NCIPI
