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), Umuyoboro wa Optical Wavelength Ikwirakwiza (OWDN) hamwe na Optical Network Unit (ONU: Optical Network Unit), nkuko bigaragara ku gishushanyo 1.OLTni 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 naOLTibikoresho. OWDN bivuga umuyoboro wa optique uri hagati yaOLTnaONU, kandi ikamenya umurongo wo gukwirakwiza kuva iOLTKuriONUCyangwa Kuva iONUKuriOLT. 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. UwitekaONUyashyizwe kumurongo wumukoresha kandi ni optique ya terefone kuruhande rwabakoresha.
Mu cyerekezo cyo hasi, uburebure butandukanye bwumurongo ld1… ldn byoherezwa kuri OWDN nyuma ya OM / OD kugwiza ibiro bikuru, kandi bigenerwa buriONUukurikije uburebure butandukanye. Mu cyerekezo cyo hejuru, abakoresha batandukanyeONUohereza optique yumurongo utandukanye lu1… lun kuri OWDN, multiplex kuri PRN ya OWDN, hanyuma wohereze kuriOLT. 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.
