Abstract
A technique for providing time division multiplexing ('TDM') and wavelength division multiplexing ('WDM') communication services to customer premises (“CP”) over a passive optical network (“PON”) includes multiplexing a downstream TDM signal with downstream WDM signals onto a fiber trunk line coupled between a central office and a remote node (“RN”), separating the downstream WDM signals from the downstream TDM signal at the RN with a wavelength selective filter, power splitting the downstream TDM signal at the RN onto a plurality of fiber access lines as split TDM signals; and recombining each of the WDM signals with a corresponding one of the split TDM signals onto a corresponding one of the fiber access lines.
