Abstract

The present invention provides an interconnect cable having selectively activated identifiers in order to facilitate the locating and positive identification of ends of the interconnect cable. The identifiers may be activated by introducing or enabling a suitable activation signal at identifier activation points provided at an end of the interconnect cable opposite an end including an identifier. The activation signal may be provided by a detection probe tool.
