Ngokuthuthuka okusheshayo kobuchwepheshe bobuhlakani bokwenziwa (AI), isidingo sokucubungula idatha kanye nomthamo wokuxhumana sifinyelele izinga elingakaze libonwe ngaphambili. Ikakhulukazi emikhakheni efana nokuhlaziywa kwedatha enkulu, ukufunda okujulile, kanye nokubala amafu, izinhlelo zokuxhumana zinezidingo eziphakeme kakhulu zesivinini esiphezulu kanye ne-bandwidth ephezulu. I-fiber yendabuko yemodi eyodwa (i-SMF) ithintwa umkhawulo we-Shannon ongewona oqondile, futhi umthamo wayo wokudlulisa uzofinyelela umkhawulo wawo ophezulu. Ubuchwepheshe bokudlulisa be-Spatial Division Multiplexing (SDM), obumelelwa yi-fiber eningi (i-MCF), busetshenziswe kabanzi kumanethiwekhi okudlulisa ahlangene akude kanye namanethiwekhi okufinyelela okubonakalayo afushane, okuthuthukisa kakhulu umthamo wokudlulisa wonke wenethiwekhi.
Imicu ye-optical ye-multi core idlula imikhawulo yemicu ye-single-mode yendabuko ngokuhlanganisa ama-fiber cores amaningi azimele ku-fiber eyodwa, okwandisa kakhulu umthamo wokudlulisa. I-fiber ejwayelekile ye-multi-core ingaba nama-fiber cores amane kuya kwayisishiyagalombili e-single-mode asatshalaliswe ngokulinganayo esikhumbeni esivikelayo esinobubanzi obungaba ngu-125um, okuthuthukisa kakhulu ikhono le-bandwidth iyonke ngaphandle kokwandisa ububanzi bangaphandle, okuhlinzeka ngesisombululo esifanele sokuhlangabezana nokukhula okuqhumayo kwezidingo zokuxhumana kubuhlakani bokwenziwa.
Ukusetshenziswa kwemicu ye-optical ye-multi-core kudinga ukuxazulula uchungechunge lwezinkinga ezifana nokuxhumeka kwe-fiber ye-multi-core kanye nokuxhumana phakathi kwemicu ye-multi-core kanye nemicu yendabuko. Kuyadingeka ukuthuthukisa imikhiqizo yezingxenye ezihlobene ne-peripheral njengezixhumi ze-fiber ze-MCF, amadivayisi okufaka nokukhipha ifeni ukuze kuguqulwe i-MCF-SCF, futhi kucatshangelwe ukuhambisana kanye nokuhlukahluka kobuchwepheshe obukhona nobezentengiselwano.
Idivayisi yokungena/ukuphuma kwefeni ye-fiber eyinhloko eminingi
Ungazixhuma kanjani izintambo ze-optical ze-multi-core nezintambo ze-optical zendabuko ze-single core? Amadivayisi e-multi-core fiber fan in and fan out (FIFO) ayizici ezibalulekile zokufeza ukuhlangana okuphumelelayo phakathi kwezintambo ze-multi-core kanye nezintambo ze-single-mode ezijwayelekile. Njengamanje, kunezindlela eziningana zokusebenzisa amadivayisi e-multi-core fiber fan in and fan out: ubuchwepheshe obuhlanganisiwe, indlela ye-bundle fiber bundle, ubuchwepheshe be-3D waveguide, kanye nobuchwepheshe be-space optics. Izindlela ezingenhla zonke zinezinzuzo zazo futhi zifanele izimo ezahlukene zohlelo lokusebenza.
Isixhumi se-fiber optic se-multi-core MCF
Inkinga yokuxhumana phakathi kwemicu ye-optical enezinsika eziningi kanye nemicu ye-optical eyodwa esesixazululiwe, kodwa ukuxhumana phakathi kwemicu ye-optical enezinsika eziningi kusadingeka kuxazululwe. Njengamanje, imicu ye-optical enezinsika eziningi ixhunywa kakhulu ngokuhlanganisa i-fusion, kodwa le ndlela inemikhawulo ethile, njengobunzima obukhulu bokwakha kanye nokugcinwa okunzima esigabeni esilandelayo. Njengamanje, ayikho indinganiso ehlanganisiwe yokukhiqizwa kwemicu ye-optical enezinsika eziningi. Umenzi ngamunye ukhiqiza imicu ye-optical enezinsika eziningi enezinhlelo ezahlukene ze-core, osayizi be-core, isikhala se-core, njll., okwandisa ngokungabonakali ubunzima bokuhlanganisa i-fusion phakathi kwemicu ye-optical enezinsika eziningi.
Imodyuli ye-MCF Hybrid ye-Multi core fiber (esetshenziswa ohlelweni lwe-EDFA optical amplifier)
Kuhlelo lokudlulisa i-optical lwe-Space Division Multiplexing (SDM), isihluthulelo sokufinyelela ukudlulisa okunamandla aphezulu, okusheshayo, kanye nebanga elide sisekukhokheleni ukulahlekelwa kokudluliselwa kwezimpawu kuma-optical fibers, kanti ama-optical amplifiers ayizingxenye ezibalulekile kule nqubo. Njengamandla abalulekile okushayela ukusetshenziswa okusebenzayo kobuchwepheshe be-SDM, ukusebenza kwama-SDM fiber amplifiers kunquma ngqo ukuthi uhlelo lonke lusebenza kahle. Phakathi kwawo, i-multi-core erbium-doped fiber amplifier (MC-EFA) isibe yingxenye ebalulekile ebaluleke kakhulu ezinhlelweni zokudlulisa ze-SDM.
Uhlelo olujwayelekile lwe-EDFA luqukethe ikakhulukazi izingxenye eziyinhloko ezifana ne-erbium-doped fiber (EDF), umthombo wokukhanya wephampu, i-coupler, i-isolator, kanye nesihlungi se-optical. Ezinhlelweni ze-MC-EFA, ukuze kufezwe ukuguqulwa okuphumelelayo phakathi kwe-multi-core fiber (MCF) kanye ne-single core fiber (SCF), uhlelo luvame ukwethula amadivayisi e-Fan in/Fan out (FIFO). Isixazululo se-EDFA se-multi-core fiber esizayo kulindeleke ukuthi sihlanganise ngqo umsebenzi wokuguqulwa kwe-MCF-SCF ezingxenyeni ezihlobene ze-optical (njenge-980/1550 WDM, i-gain flattening filter GFF), ngaleyo ndlela kube lula ukwakheka kwesistimu futhi kuthuthukiswe ukusebenza okuphelele.
Ngokuthuthuka okuqhubekayo kobuchwepheshe be-SDM, izingxenye ze-MCF Hybrid zizohlinzeka ngezixazululo ze-amplifier ezisebenza kahle kakhulu neziphansi zezinhlelo zokuxhumana ze-optical ezinekhono eliphezulu zesikhathi esizayo.
Kulesi simo, i-HYC ithuthukise izixhumi ze-fiber optic ze-MCF eziklanyelwe ngqo ukuxhumeka kwe-fiber optic ye-multi-core, ezinezinhlobo ezintathu zesikhombimsebenzisi: uhlobo lwe-LC, uhlobo lwe-FC, kanye nohlobo lwe-MC. Izixhumi ze-fiber optic ze-LC zohlobo lwe-LC kanye nohlobo lwe-FC ze-MCF multi-core zishintshiwe kancane futhi zaklanywa ngokusekelwe ezixhumini zendabuko ze-LC/FC, zenza ngcono umsebenzi wokubeka nokugcina, zithuthukise inqubo yokuhlanganisa, ziqinisekise izinguquko ezincane ekulahlekelweni kokufakwa ngemva kokuhlanganisa okuningi, futhi zithathe indawo ngqo yezinqubo zokuhlanganisa ezibizayo zokuhlanganisa ukuqinisekisa ukuthi kulula ukuzisebenzisa. Ngaphezu kwalokho, i-Yiyuantong iphinde yaklama isixhumi se-MC esizinikele, esinosayizi omncane kunezixhumi zendabuko ze-interface futhi singasetshenziswa ezindaweni ezixinene kakhulu.
