Abstract
A broadcast delivery system allows the delivery of broadband broadcast services over a WDM Passive Optical Network. These broadband services can be carried on optical broadband carriers or signals in a cost-effective manner by utilizing shared dispersion-compensated fiber (DCF) over a group of feeder lines or a group of PONs. A broadband optical signal is provided over a plurality of feeder lines. Each feeder line is connected to a remote node for distribution to subscribers. One dispersion-compensated fiber is shared for a plurality of feeder lines.
