Abstract

We demonstrate simultaneous delivery of four independent digital broadcast television services over a wavelength-division-multiplexing (WDM) passive optical network (PON) by spectrally slicing erbium-doped fiber-amplified light-emitting diodes. The composite bandwidth of 2 GHz carries more than 320 channels of digital television, and is delivered independently of private point-to-point services, which are possible over the WDM PON architecture. The effects of misalignment between the transmitter and receiver optical filters are studied for the WDM PON and for a standard passive splitter PON.
