Abstract
This paper presents the architecture of a green and flexible WDM-PON access network. We propose the segmentation of a broadband source into smaller frequency windows by means of a wave shaper filter. A central controller commands the configuration of physical network parameters such as the optical bandwidth delivered by the filter and the modulation format of the service to be transported in the network. Different optical bandwidths were defined for the experimental demonstration and two modulation formats were evaluated in our approach. Results found an effective bandwidth of 3 GHz for optical bandwidths below 1 nm. Broader optical pass bands reduce the bandwidth but improve the signal quality measured in the receiver due to a relative higher average optical power available in the photo detector.
