Abstract
The present invention provides a dielectric optical fiber cable which is capable of being remotely detected while buried. Specifically, this invention incorporates a detectable and easily removable locating element which is attached to the optical fiber cable by a web defined by the jacket extending over both the optical fiber cable and the locating element. The web allows for the locating strand to be easily removed once separation of the locating element from the optical fiber cable is initiated. The web is designed to allow the initial tear to propagate into a precise longitudinal tear along a predetermined length of the optical fiber cable.
