This research proposes the development of Optical Network Units by introducing an all optical Filter. This optical filter can treat WDM and PDM technology at the same time enabling us to send a channel on the horizontal and vertical of the same wavelength .The hybrid WDM-PDM technology allows to delivery double channels for users without any changing in infrastructure between optical central office and user . Firstly , this article prove the idea of hybrid WDM-PDM technology by OptiSystem7.0 simulator, secondly we study proposed all optical Filter for three cases of optical access: WDMPDM( Downstream), WDM(Downstream)/( TDM(Upstream) , WDM(Downstream)/ WDM(Downstream) recommended by the international communication federation, ICF.
