In this paper, we present results of a proof-of-concept laboratory demonstration where the new ITU-T wavelength grid for Coarse Wavelength Division Multiplexing (CWDM) is applied to a Passive Optical Network (PON) for metro access. The investigated demonstration network simulates an architecture described best as a CWDM overlay to a generic gigabit PON that is in accordance with ITU-T G.983/984...
