<p>An arrangement is provided for consolidating equipment, services, and information and for distributing information from a consolidated information distribution center (CIDC) to a plurality of head ends using spectrally efficient transport. The CIDC generates an optical signal encoded with information of multiple channels aggregated through a multi-level encoding scheme and sends the optical signal to a plurality of head ends via an optical fiber. When a head end receives the optical signal, it decodes the optical signal in multiple stages to produce information of multiple data streams, from which desired data streams are selected.</p> |
