Digital video overlay for passive optical networks
Abstract
A passive optical network (PON) is described herein that is capable of using a wavelength division multiplexing (WDM) digital video overlay to deliver a digital video signal on a 1550nm center-wavelength from a video head-end to an end-user. The PON is also capable of transmitting voice and data on a 1480-1500nm band to the end-user and further capable of receiving voice and data on a 1260-1360nm band from the end-user. The digital video signal can be generated for example from an analog broadcasted television signal, a video-on-demand video signal or a high definition television signal. A set-top box used by the end-user which interfaces with the passive optical network is also described herein.
