Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having an interior surface and an exterior surface. The interior surface defines a central bore extending along a longitudinal axis of the optical fiber cable, and the exterior surface defines an outermost surface of the optical fiber cable. At least one subunit is disposed within the central bore. Each of the at least one subunit includes at least one optical fiber disposed within a buffer tube. A plurality of ultrahigh molecular weight polyethylene (UHMWPE) tensile yarns are positioned around the at least one subunit and extend along the longitudinal axis. A layer of a bedding compound is disposed between the plurality of UHMWPE tensile yarns and the cable jacket.

A piezoelectric thread that includes a core thread; and a piezoelectric film wound around the core thread. The piezoelectric thread is constructed to generate a charge by energy imparted from outside of the piezoelectric thread.
