Claim:
1. A strain-sensing cable comprising: a jacket having a first length extending between a first end and a second end of the cable, wherein the jacket includes a polymer layer defining an outermost surface of the cable; a first optical fiber embedded within the polymer layer of the jacket such that the jacket surrounds the first optical fiber, the first optical fiber configured to experience a strain applied to the cable and a temperature of the cable; and a second optical fiber located within the jacket, wherein the second optical fiber is isolated from the strain applied to the cable and is configured to experience the temperature of the cable, and wherein a length of the first optical fiber between the first end and the second end of the cable is equal to the first length and a length of the second optical fiber between the first end and the second end of the cable is greater than the first length.
