Optical fiber cable from a Central Office (CO) to a Service Area Interface (SAI) Optical Line Terminal (OLT) box may have a plurality of optical fibers, each fiber having at least one conductive sheath to can propagate an identifying signal. Optical fibers that emit a signal with identifying information, or other useful information, may be advantageous when, for example, the fiber optic cable holds fibers owned by more than one content or service provider. A further advantage may be that a signal may be designated to a particular address, thereby facilitating the installation of fiber optic service to a customer.
