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.

Abstract: A fiber optic cable comprises a core subassembly comprising at least one optical fiber and a tube surrounding the optical fiber. A multi-layered jacket surrounds the core subassembly, wherein the jacket comprises an inner layer comprising a flame retardant (FR) material and an outer layer comprising a non flame retardant material having a lower coefficient of friction than the flame retardant material. A method of manufacturing an optical fiber cable includes providing a core subassembly and co-extruding a multi-layered jacket around the core subassembly, wherein the multi-layered jacket includes an inner layer comprising a flame retardant (FR) material and an outer layer comprising a non flame retardant material having a lower coefficient of friction than the flame retardant.
