WDM PON waa shabakad indho-indhayn indho-indhayn ah oo dhibic-ilaa-dhibcood adeegsanaysa tignoolajiyada isku-dhufashada ee qaybinta mawjada. Taasi waa, in fiber isku mid ah, tirada mowjadaha loo isticmaalo labada jiho waa in ka badan 3, iyo isticmaalka tignoolajiyada multiplexing qaybinta wavelength si loo gaaro uplink heli karo siin kara bandwidth shaqo weyn oo qiimo jaban, taas oo ah jihada horumarinta muhiimka ah. mustaqbalka helitaanka fiber Optical. Nidaamka caadiga ah ee WDM PON wuxuu ka kooban yahay saddex qaybood: Terminalka khadka indhahaOLTShabakadda Qaybinta Wavelength Optical (OWDN) iyo Unugga Shabakadda indhaha (Optical Network Unit)ONU: Unugga shabakadda indhaha), sida ku cad sawirka 1.OLTwaa qalabka xafiiska dhexe, oo ay ku jiraan mawjadaha dhererka indhaha ee multiplexer/demultiplexer (OM/OD). Guud ahaan, waxa ay leedahay hawlo ay ka mid yihiin xakamaynta, beddelka, iyo maamulka. OM/OD ee xafiiska dhexe jir ahaan waa laga sooci karaaOLTqalabka. OWDN waxaa loola jeedaa shabakada indhaha ee ku taal inta u dhaxaysaOLTiyoONU, oo garwaaqsada qaybinta hirarka dhererka kaOLTkuONUama kaONUkuOLT. Isku xirka jireed waxaa ka mid ah fiber feeder iyo noode fog oo dadban (PRN: Passive Remote Node). PRN inta badan waxaa ku jira shaabada hagaha waveguide kuleyl aan dareen lahayn (AAWG: Athermal Arrayed Waveguide Grating). AAWG waa mowjadda-dhererka-xasaasi ah aaladda indho-indheynta indho-indheynta oo qabata isku-dhufashada mowjadda dhererka indhaha iyo hawlo-fududeynta. TheONUwaxa la dhigayaa terminaalka isticmaalaha waana qalab terminal indhaha ah oo dhinaca isticmaalaha ah.
