Abstract
A fiber optic cable includes a plurality of optical fibers and an optical sensor. The optical sensor includes a first optical coupler and a first mirror. The first optical coupler is coupled to a first of the optical fibers and to a second of the optical fibers at a first sensor takeout location. The first mirror is coupled to the first of the optical fibers at a second sensor takeout location. The first sensor takeout location is longitudinally offset from the second sensor takeout location.
