WDM PON ni point-to-point-passique optique umuyoboro ukoresheje tekinoroji yo kugabana umurongo wa tekinoroji.Nukuvuga ko, muri fibre imwe, umubare wuburebure bwumurongo ukoreshwa mubyerekezo byombi urenze 3, kandi gukoresha ikoreshwa rya tekinoroji yo kugabana umurongo wa tekinoroji kugirango ugere kuri uplink irashobora gutanga umurongo munini wogukora ku giciro gito, kikaba ari icyerekezo cyingenzi cyiterambere kuri ahazaza Optical fibre igera.Sisitemu isanzwe ya WDM PON igizwe nibice bitatu: Optical Line Terminal (OLT), Optical Wavelength Distribution Network (OWDN) hamwe na Optical Network Unit (ONU: Optical Network Unit), nkuko bigaragara ku gishushanyo cya 1. OLT ni ibikoresho byo mu biro bikuru, harimo optique yumurongo wo kugabana multiplexer / demultiplexer (OM / OD).Mubisanzwe, ifite imirimo nko kugenzura, guhana, no kuyobora.OM / OD y'ibiro bikuru birashobora gutandukana kumubiri nibikoresho bya OLT.OWDN bivuga umuyoboro wa optique uri hagati ya OLT na ONU, kandi ukamenya gukwirakwiza uburebure bwumurongo uva kuri OLT ukagera kuri ONU cyangwa kuva kuri ONU ukagera kuri OLT.Ihuza ryumubiri ririmo fibre fibre hamwe na pasiporo ya kure (PRN: Passive Remote Node).PRN ikubiyemo cyane cyane ubushyuhe butagaragara bwa arrayguide (AAWG: Athermal Arrayed Waveguide Grating).AAWG nigikoresho cyumubyigano wunvikana pasitiki optique ikora optique yumurongo wa optique ya Multlexing na demultiplexing.ONU ishyirwa kumurongo wumukoresha kandi ni igikoresho cyiza cya optique kuruhande rwabakoresha.
Mu cyerekezo cyo hasi, uburebure butandukanye butandukanye ld1… ldn bwoherezwa kuri OWDN nyuma ya OM / OD kugwiza ibiro bikuru, kandi bigenerwa buri ONU ukurikije uburebure butandukanye.Mu cyerekezo cyo hejuru, abakoresha batandukanye ONU basohora uburebure butandukanye bwa optique ya lu1… lun kuri OWDN, multiplex kuri PRN ya OWDN, hanyuma ikohereza kuri OLT.Uzuza inzira yo hejuru no kumanuka yohereza ibimenyetso bya optique.Muri byo, uburebure bwumurongo wa ldn hamwe nuburebure bwo hejuru bwumurongo urashobora gukora mumurongo umwe cyangwa umurongo utandukanye.
