WDM PON inzvimbo-kune-point passive optical network inoshandisa wavelength division multiplexing tekinoroji. Kureva, mufiber imwe chete, nhamba yewavelengths inoshandiswa kumativi ose inopfuura 3, uye kushandiswa kwewavelength division multiplexing tekinoroji kuti uwane uplink access inogona kupa hukuru hwekushanda bandwidth pamutengo wakaderera, inova yakakosha kutungamira kutungamira kune. remangwana Optical faibha kuwana. Yakajairika WDM PON system ine zvikamu zvitatu: Optical Line Terminal (OLT), Optical Wavelength Distribution Network (OWDN) uye Optical Network Unit (ONU: Optical Network Unit), sezvakaratidzwa mumufananidzo 1.OLTndiyo yepakati hofisi midziyo, kusanganisira optical wavelength division multiplexer/demultiplexer (OM/OD). Kazhinji, ine mabasa akadai sekutonga, kuchinjana, uye manejimendi. Iyo OM / OD yehofisi yepakati inogona kupatsanurwa kubva kuOLTmidziyo. OWDN inoreva iyo optical network iri pakati peOLTuyeONU, uye inoona kugoverwa kwewavelength kubva kuOLTkuONUkana kubva kuONUkuOLT. Kubatana kwemuviri kunosanganisira feeder fiber uye passive kure node (PRN: Passive Remote Node). PRN inonyanya kusanganisira thermally insensitive arrayed waveguide grating (AAWG: Athermal Arrayed Waveguide Grating). AAWG iwavelength-sensitive passive optical mudziyo inoita optical wavelength multiplexing uye demultiplexing mabasa. TheONUinoiswa pachiteshi chemushandisi uye ndeye optical terminal mudziyo padivi remushandisi.
