A fiber optic cable can comprise a tape that extends along the cable and that facilitates locating the cable when the cable is buried underground. The tape can comprise a film of nonconductive material, such as plastic, with an overlaying pattern of conductive patches. The conductive patches can comprise regions of metallic film laminated with or otherwise adhering to the nonconductive film. Spacing between the conductive patches can provide patch-to-patch isolation so that the ends of the cable are electrically isolated from one another. Field personnel can locate the underground cable by scanning the ground with a metal detector.
