Njengoko sisazi, ukusukela ngo-1990s, itekhnoloji ye-WDM ye-WDM isetyenziselwe amakhonkco ama-fiber-haul-optic optic okanye amawaka eekhilomitha. Kwimimandla emininzi yelizwe, izibonelelo zefayibha zexabiso lezinto zexabiso lexabiso eliphezulu, ngelixa iindleko zezinto ezidleleni ziphantsi kakhulu.
Nangona kunjalo, ngokuqhushumba kwamaxabiso edatha enjenge-5G, itekhnoloji ye-WDM iya isibakala kwizikhonkwano ezimfutshane-haul ezimfutshane ngokunjalo, ezikhutshelwe kakhulu kwiindleko kunye nobungakanani beendibano zokudlula.
Okwangoku, ezi thungelwano zisaxhomekeka kumawakawaka eefible zemozulu ezidluliselwe ngokuhambelana neendlela zokwahlulahlula-hlulo ze-GBBIng, ngamanqanaba amancinci e-GBITER nganye, kunye nenani elincinci lezicelo ezinokwenzeka kwi-T-CHART.
Nangona kunjalo, kwikamva elibonakalayo, umxholo wokudibana okuqhelekileyo kwendawo kungekudala uza kufikelela kwimida ye-scaldres, kwaye kuya kufuneka aphethwe lube nolwakhiwo lwedatha kwifayibha nganye kwi-fiber nganye ukuze kugcinwe amaxabiso edatha. Oku kunokuvula yonke indawo entsha yokwenza isicelo seTekhnoloji ye-WDM, apho ubukhulu bezinto eziphezulu zenani leziteshi kunye nenqanaba ledatha libalulekile.
Kule meko,I-verator ye-optical ye-optical (FCG)Idlala indima ephambili njenge-compact, eqingqiweyo, umthombo wamanzi amnyama omncinci onokuthi unike inani elikhulu labathwali abachazwe kakuhle. Ukongeza, ithuba elibaluleke kakhulu le-pics yendlela yokuba imigca yokudibanisa ilungeleleneyo, ngaloo ndlela iphumle imfuneko ye-channel yentsebenzo kwaye inqande ulawulo lwe-handling oluya kufunwa ngumgca we-DFB isebenzisa i-DFIROLS.
Kubalulekile ukuba uqaphele ukuba ezi zibonelelo zisebenza kungekuphela nje kudluliselo lwe-WDM kodwa kunye nabamkeli babo, apho i-Oscillator yaseKhaya yaseKhaya (i-Oscillator yaseKhaya (i) i-crays ithathelwe indawo ngumvelisi wokudibanisa. Ukusetyenziswa kwe-LO Teverators kuqhubela phambili ukuqhubekeka kwesiginali sedijithali yeendlela ze-WDM, ngaloo ndlela kuncitshiswa kobunzima bengxolo kunye nokukhula kwengxolo yengxolo.
Ukongeza, ukusetyenziswa kwe-LO LUROCNANS NOKWENZA ISIQINISEKISO SOKUVUNYELWA KWEXESHA LOKUVUNYELWA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWAKHONA KWABO BOKUGQIBELA KWI-FITERORY KWI-FITE YAMALUNGISELELO. Ukongeza kwezi zibonelelo zothungulo zihambelana ngokudibeneyo, ubungakanani obuncinci kunye nemveliso enobuninzi eneendleko kukwayeyona nto iphambili kwi-WDM yexesha elizayo.
Ke ngoko, phakathi kwamagama ohlanganisiweyo emiqondiso, izixhobo ze-Chip-zinza inzala ethile. Xa idityaniswa nesekethe ehlanganisiweyo esihlanganisiweyo semozulu ye-Potonaic yoMqondiso weNdalo, i-Contring kunye nokwamkela, i-WDM enesitshixo inokubanjwa kwi-compact, i-WDM esebenzayo ye-TIBE ye-TBIRE / i-tiber ye-TBIR kwi-tiber nganye.
Lo mfanekiso ulandelayo ubonakalisa isikimo se-WDM esebenzisa i-FCG ye-FCG njenge-Multi-Wave-Wavenqngsns Ngapha koko, umqondiso wabekwa phantsi kwe-quadestical quadrature ye-quadlituc yemo yokusebenzela ngokugqibeleleyo (se).
Kwindawo edlulayo, iitshaneli zibuyiselwa kwi-Counter (MUX) kunye neempawu ze-WDM zidluliselwa kwimowudi enye yefibre. Ekuqaleni kokuphela, i-Waveletch ye-Wavegeng GatR (WDM RX), isebenzisa i-Oscillator yendawo ye-2 ye-FCG ye-Mulwanderd ohambelana nayo. Amajelo eempawu ze-WDM ze-WDM zahlulwe yi-dedeptracptions kwaye yondliwe kwi-cohrant ye-cosher ye-cohyr (coh. Rx). Apho i-Deedping Readrency ye-Oscillator yendawo isetyenziswa njengesalathiso sesigaba ngasinye. Ukusebenza kwe-WDM ICDM ngokucacileyo kuxhomekeke kubungakanani obukhulu kwi-generator yokudibanisa, ngakumbi ububanzi bemigca yokukhanya kunye namandla omehlo kumgca ngamnye.
Ewe kunjalo, itekhnoloji ye-ofisi ye-pical frequency ikwinqanaba lophuhliso, kwaye iimeko zayo zesicelo kunye nobungakanani bentengiso zincinci. Ukuba inokoyisa iibhotile zobugcisa, ukunciphisa iindleko kunye nokuphucula ukuthembeka, kuya kuba nakho ukufezekisa izicelo zenqanaba lezimali kusulelo olungafaniyo.
