Abstract: An optical fiber composite wire strand, a manufacturing method thereof, and a strain measuring method are provided to prevent a fiber bragg grating sensor from being damaged by external shock, by disposing the fiber bragg grating sensor in a through-hole of a first steel wire, thereby exactly measuring the strain rate. In an optical fiber composite wire strand(20), a through-hole(211) is formed on at least one of first and second steel wires(21,22) of the wire strand in a longitudinal direction of the steel wire. The first steel wire is positioned in the center. Six strands of the second steel wires are twisted with surrounding the first steel wire. An optical fiber sensor is disposed in the through-hole. In particular, a fiber bragg grating sensor(10) having grating sensing units arranged on an optical fiber at regular intervals is used.
