Abstract
An arrangement is provided for transporting information from a central information distribution center (CIDC) to locations where such information is intended. Upon receiving a request for narrowcast information to be delivered to a node associated with a head end, the CIDC selects the requested information, generates an optical signal encoded with the requested information using information channels dedicated to narrowcast information transport for the node, and sends the optical signal to the head end via an optical fiber. When the head end receives the optical signal, the narrowcast information transport channels dedicated to the node are translated into subcarriers acceptable to the node before the requested narrowcast information is forwarded to the node.
