ABSTRACT:
The present invention provides a dielectric optical fiber cable which is capable of being remotely detected while buried. Specifically, this invention incorporates magnetic materials into existing elements of high strength sheath systems which are commonly used to enhance the tensile properties of many optical fiber cables. Embodiments of the present invention include various configurations of strength member systems each comprising a plurality of longitudinally aligned glass roving or yarns which have neodymium iron boron compounded into an epoxy matrix.
