Abstract

We present a novel scheme to construct non-wavelength-selective optical network unit (ONU) in hybrid wavelength division multiplexing and optical code division multiple access based passive optical networks (WDM/OCDMA-PON) by making use of the broad spetrum band of superstructure fiber Bragg gratings (SSFBGs). The experiment results reveal that the spectrum-sliced encoded signals from different wavelength channels can be successfully decoded with the same SSFBGs, and thus the proposed colorless ONU scheme is proved to be feasible.
