Ngokuthuthuka okusheshayo kobuchwepheshe be-artificial intelligence (AI), isidingo sokucutshungulwa kwedatha namandla okuxhumana sesifinyelele izinga elingakaze libonwe. Ikakhulukazi emikhakheni efana nokuhlaziywa kwedatha enkulu, ukufunda okujulile, ne-cloud computing, izinhlelo zokuxhumana zinezidingo ezikhulayo eziphakeme zejubane eliphezulu kanye nomkhawulokudonsa ophezulu. Ifayibha yemodi eyodwa yendabuko (i-SMF) ithintwa umkhawulo we-Shannon ongaqondile, futhi umthamo wayo wokudlulisela uzofinyelela umkhawulo wawo ophezulu. Ubuchwepheshe bokudlulisa i-Spatial Division Multiplexing (SDM), obumelwe yi-multi-core fiber (MCF), busetshenziswe kabanzi kumanethiwekhi okudlulisela ahambisanayo amabanga amade kanye namanethiwekhi okufinyelela okubona amabanga amafushane, athuthukisa kakhulu umthamo wokudlulisela jikelele wenethiwekhi.
Ama-Multi core optical fibers anqamula imikhawulo yemicu yemodi eyodwa yendabuko ngokuhlanganisa ama-fiber cores amaningi azimele abe yifayibha eyodwa, okwandisa kakhulu umthamo wokudlulisela. I-multi-core fiber ejwayelekile ingase iqukathe ama-fiber cores amane kuya kwayisishiyagalombili emodi eyodwa asakazwe ngokulinganayo emgodleni ovikelayo nobubanzi obungaba ngu-125um, othuthukisa kakhulu amandla omkhawulokudonsa ngaphandle kokwandisa ububanzi obungaphandle, okuhlinzeka ngesixazululo esikahle sokuhlangabezana nokukhula okuqhumayo kwezidingo zokuxhumana kubuhlakani bokwenziwa.
Ukusetshenziswa kwama-multi-core optical fibers kudinga ukuxazulula uchungechunge lwezinkinga ezifana noxhumo lwe-multi-core fiber kanye nokuxhumana phakathi kwama-multi-core fibers kanye nemicu yendabuko. Kuyadingeka ukuthi kuthuthukiswe imikhiqizo yengxenye ehlobene ne-peripheral efana nezixhumi zefayibha ze-MCF, amadivaysi afaka umoya futhi aphehlelele ukuguqulwa kwe-MCF-SCF, futhi kucatshangelwe ukuhambisana nokuvumelana kwendawo yonke nobuchwepheshe obukhona nobohwebo.
I-Multi core fiber fan in/fan out device
Ungawaxhuma kanjani ama-multi-core optical fibers nge-traditional single core optical fibers? Amadivaysi e-Multi core fiber fan in and fan out (FIFO) ayizici ezibalulekile zokuzuza ukuhlangana okuphumelelayo phakathi kwamafayibha abalulekile amaningi kanye nemicu evamile yemodi eyodwa. Njengamanje, kunobuchwepheshe obuningi bokusebenzisa amadivaysi e-multi-core fiber fan in and fan out: ubuchwepheshe obuhlanganisiwe, indlela ye-bundle fibre bundle, ubuchwepheshe be-3D waveguide, kanye nobuchwepheshe be-space Optics. Izindlela ezingenhla zonke zinezinzuzo zazo futhi zifanele izimo ezihlukene zohlelo lokusebenza.
Multi core fiber MCF fibre optic isixhumi
Inkinga yokuxhuma phakathi kwama-multi-core optical fibers kanye ne-single core optical fibers isixazululiwe, kodwa ukuxhumana phakathi kwama-multi-core optical fibers kusadinga ukuxazululwa. Njengamanje, ama-multi-core optical fibers axhunywe kakhulu ngokuhlanganisa ukuhlanganisa, kodwa le ndlela futhi inemikhawulo ethile, njengobunzima bokwakha obukhulu kanye nokugcinwa okunzima esigabeni sakamuva. Njengamanje, alikho izinga elihlanganisiwe lokukhiqizwa kwama-multi-core optical fibers. Umkhiqizi ngamunye ukhiqiza ama-multi-core optical fibers anezinhlelo ezihlukene eziwumgogodla, osayizi abayinhloko, ukuhlukaniswa okuyisisekelo, njll., okwandisa ngokungabonakali ubunzima bokuhlanganisa ukuhlanganisa phakathi kwama-multi-core optical fibers.
I-Multi core fiber MCF Hybrid module (isetshenziswa ohlelweni lwe-EDFA optical amplifier)
Kuhlelo lokudlulisa amehlo lwe-Space Division Multiplexing (SDM), isihluthulelo sokufinyelela ukudluliselwa kwamandla aphezulu, isivinini esikhulu, kanye nebanga elide sisekunxephezeleni ukulahleka kokudluliselwa kwamasignali kuma-optical fibers, futhi ama-optical amplifiers ayizingxenye ezibalulekile ezibalulekile kule nqubo. Njengamandla okushayela abalulekile okusetshenziswa okungokoqobo kobuchwepheshe be-SDM, ukusebenza kwama-SDM fiber amplifiers kunquma ngokuqondile ukuthi kungenzeka yini uhlelo lonke. Phakathi kwazo, i-multi-core erbium-doped fibre amplifier (MC-EFA) isibe ingxenye esemqoka ebalulekile ezinhlelweni zokudlulisa ze-SDM.
Isistimu ye-EDFA evamile yakhiwa ikakhulukazi izingxenye eziyinhloko ezifana ne-erbium-doped fiber (EDF), umthombo wokukhanya wepompo, i-coupler, i-isolator, nesihlungi sokubona. Ezinhlelweni ze-MC-EFA, ukuze kuzuzwe ukuguqulwa okuphumelelayo phakathi kwe-multi-core fiber (MCF) ne-single core fiber (SCF), uhlelo ngokuvamile lwethula amadivayisi we-Fan in/Fan out (FIFO). Isixazululo sesikhathi esizayo se-multi-core fiber EDFA kulindeleke ukuthi sihlanganise ngokuqondile umsebenzi wokuguqulwa kwe-MCF-SCF ezingxenyeni ezibonakalayo ezihlobene (ezifana ne-980/1550 WDM, sithole isihlungi se-GFF esicaba), ngaleyo ndlela senze ukwakheka kwesistimu kube lula futhi kuthuthukiswe ukusebenza okuphelele.
Ngokuthuthuka okuqhubekayo kobuchwepheshe be-SDM, izingxenye ze-MCF Hybrid zizohlinzeka ngezixazululo ezisebenza kahle neziphansi ze-amplifier yezinhlelo zokuxhumana zamandla aphezulu ezizayo.
Kulo mongo, i-HYC ithuthukise izixhumi ze-MCF ze-fiber optic eziklanyelwe ngokuqondile uxhumo lwe-multi-core fibre optic, ezinezinhlobo ezintathu zokusebenzelana: uhlobo lwe-LC, uhlobo lwe-FC, nohlobo lwe-MC. Uhlobo lwe-LC kanye nezixhumi zohlobo lwe-FC ze-MCF ze-multi-core fibre optic zishintshiwe kancane futhi zaklanywa ngokusekelwe kuzixhumi ezivamile ze-LC/FC, zandisa indawo kanye nomsebenzi wokugcinwa, ukuthuthukisa inqubo yokuhlanganisa ukugaya, ukuqinisekisa izinguquko ezincane ekulahlekeni kokufakwa ngemva kokuhlanganisa okuningi, futhi kushintshe ngokuqondile izinqubo zokuhlanganisa ezibizayo ukuze kuqinisekiswe ukusetshenziswa. Ngaphezu kwalokho, i-Yiyuantong iphinde yaklama isixhumi esizinikele se-MC, esinosayizi omncane kunezixhumi zohlobo lwesixhumi esibonakalayo esivamile futhi singasetshenziswa ezindaweni eziminyene kakhulu.
