Abstract:
1. A Wavelength Division Multiplexed Orthogonal Frequency Division Multiple Access Passive Optical Network (WDM-OFDMA-PON), comprising: a central office optical line terminal (CO-OLT) comprising downstream OFDMA transmitters and continuous wave (CW) lasers and upstream coherent OFDMA receivers; a downstream path from the CO-OLT to optical network units (ONUs); an upstream path from said ONUs to the CO-OLT wherein the CO-OLT comprises one or more wavelength division multiplexing arrayed waveguide gratings (WDM AWGs) coupled to a diplexer and wherein the diplexer aggregates OFDMA and CW signals and transmitted over the downstream SSMF to a local exchange (LE), where downstream signals are optically amplified and routed with a second diplexer or second optical coupler, AWGs, and third diplexer or third optical coupler into downstream/upstream (DS/US) wavelength pairs for distribution to the OFDMA-PONS.
