Abstract
A system and method of delivering fiber optic communication service is provided. The method includes monitoring a strain signal generated by a strain-sensing optical fiber embedded in a roadway. The method includes comparing the strain signal to a predetermined allowable strain threshold of an optical communication cable associated with the strain-sensing optical fiber. The method includes relieving strain at a position along a length of the optical communications cable when the strain signal is determined to exceed the predetermined allowable strain threshold.
