Kusukela uKao ephakamise ukuthi imicu ye-optical ingasetshenziswa ekudluliseni kwezokuxhumana, ubuchwepheshe bokuxhumana kwe-optical buye bachuma kanye nemicu ye-optical, baguqula umhlaba. Imicu ye-optical ingabhekwa njengesisekelo sobuchwepheshe bokuxhumana kwe-optical, futhi cishe bonke ubuchwepheshe bokudlulisa i-optical manje budinga imicu ye-optical njengendlela yokudlulisela.
Njengamanje, izinhlobo eziningi ezahlukene zemicu ye-optical ziye zathuthukiswa embonini ukuze zisetshenziswe ngezindlela ezahlukene, kodwa zonke zinezinkinga ezahlukene, okuholela ekungahambelani kahle kwezinto zonke.
Imicu ye-optical esetshenziswa njengamanje ekudlulisweni kwesistimu ye-WDM ikakhulukazi imicu yemodi eyodwa njenge-G.652, G.655, G.653 kanye ne-G.654.
● I-fiber ye-G.652 inqunyelwe ekuqondisweni kokudluliselwa okuqondile ngenxa yokulahlekelwa kwayo kokudluliselwa kanye nezici ezingezona eziqondile;
● I-fiber ye-G.655 inomphumela oqinile ongewona owe-linear ngenxa yokusabalala kwe-fiber encane kanye nendawo encane esebenza kahle ye-cross-sectional, futhi ibanga lokudlulisela liyi-60% kuphela yalelo le-G.652;
● I-fiber ye-G.653 inokuphazamiseka okukhulu okungeyona imigqa phakathi kweziteshi zesistimu ye-DWDM ngenxa yokuxubana kwamagagasi amane, futhi amandla okufaka i-fiber aphansi, okungathandi ukudluliswa kwe-WDM yeziteshi eziningi ngaphezu kuka-2.5G;
● I-fiber ye-G.654 izoba nomthelela omkhulu ekudlulisweni kwesistimu ngenxa yokuphazamiseka kwe-multi-optical okuvela kumamodi aphezulu futhi, ngesikhathi esifanayo, ngeke ikwazi ukuhlangabezana nezidingo zokwandiswa kokudluliselwa kwesikhathi esizayo kuma-S, E, kanye nama-O band.
Ukusebenza kabi kwemicu ye-optical evamile emakethe yamanje nakho kuphoqa imboni ukuthi ithuthuke kubuchwepheshe be-optical fiber yesizukulwane esilandelayo ngokushesha okukhulu. I-LEE, umhleli oyinhloko wezobuchwepheshe womugqa womkhiqizo we-optical eShenzhen Aixton Cable Co., Ltd., ubheka umbono we-optical fiber yesizukulwane esilandelayo njengenye yezinselelo ezinkulu eziyisishiyagalolunye ezibhekene nobuchwepheshe obubalulekile bokuxhumana kwe-optical eminyakeni eyishumi ezayo. Ukholelwa ukuthi ukuze kuhlangatshezwane nezidingo zebanga eliqhubekayo kanye nomthamo ophindwe kabili, kanye nokuhambisana noMthetho Wokukhanya kaMoore ekuthuthukisweni kwemboni yokuhlukanisa ubude be-wavelength, isizukulwane esilandelayo semicu ye-optical kumele sibe nezici ezilandelayo: Okokuqala, ukusebenza okuphezulu, ukulahlekelwa okuphansi kwangaphakathi, kanye nokumelana nemiphumela engeyona i-linear; okwesibili, umthamo ophezulu, ohlanganisa ububanzi obugcwele noma obubanzi obutholakalayo; kanti okwesithathu, izindleko eziphansi kanye nokukwazi ukwakheka, okuhlanganisa nokulula kokukhiqiza, ngezindleko ezifana noma eziseduze nalezo ze-G.652 fiber, ukulula kokusetshenziswa, kanye nokulula kokugcinwa.
