Abstract
A fiber optic cable is described that includes a core, a cladding over the core, and a plurality of optical events on at least one of the core and cladding. The plurality of optical events are constructed and arranged to alter a signal transmitted through the cable, where the plurality of optical events define a signature key of the cable. The signature key can be used in various electronic devices and systems, such that a mode of operation is disabled or enabled based on whether the correct fiber optic cable is installed.
