Ngophuhliso olukhawulezayo lwetekhnoloji ye-Artificial Intelligence (AI), imfuno yokusetyenzwa kwedatha kunye nomthamo wonxibelelwano ufikelele kwinqanaba elingazange libonwe ngaphambili. Ngokukodwa kwiinkalo ezifana nohlalutyo olukhulu lwedatha, ukufunda okunzulu, kunye ne-computing yefu, iinkqubo zonxibelelwano zineemfuno eziphakamileyo zesantya esiphezulu kunye ne-bandwidth ephezulu. I-fiber ye-single-mode yendabuko (i-SMF) ichaphazeleka ngumda we-Shannon ongaqhelekanga, kwaye umthamo wayo wokuhambisa uya kufikelela kumda ophezulu. I-Spatial Division Multiplexing (SDM) iteknoloji yothumelo, emelwe yi-multi-core fiber (MCF), isetyenziswe ngokubanzi kuthungelwano oluhambelana nomgama omde kunye nothungelwano olufutshane lokufikelela kwi-optical access networks, iphucula kakhulu umthamo wothumelo jikelele wothungelwano.
Iifiber ezininzi ezingundoqo zamehlo ziqhekeza imida yeentsinga zemowudi enye ngokudibanisa ii-fiber cores ezininzi ezizimeleyo kwifiber enye, ukwandisa kakhulu umthamo wothumelo. I-fiber ye-multi-core fiber inokuthi iqulethe i-fiber cores ezine ukuya kwezisibhozo zendlela enye esasazwa ngokulinganayo kwi-sheath ekhuselayo enobubanzi obumalunga ne-125um, iphucula ngokubonakalayo amandla obubanzi be-bandwidth ngaphandle kokunyusa i-diameter yangaphandle, inika isisombululo esifanelekileyo ukuhlangabezana nokukhula okugqabhukileyo kweemfuno zonxibelelwano kubukrelekrele bokwenziwa.
Ukusetyenziswa kwe-multi-core optical fibers kufuna ukuxazulula uluhlu lweengxaki ezifana nokudibanisa i-fiber multi-core kunye nokudibanisa phakathi kwee-multi-core fibers kunye neentambo zendabuko. Kuyimfuneko ukuphuhlisa iimveliso zecandelo elinxulumene ne-peripheral ezifana nezihlanganisi zefayibha ze-MCF, i-fan in kunye ne-fan out izixhobo zokuguqulwa kwe-MCF-SCF, kwaye uqwalasele ukuhambelana kunye nendalo yonke kunye nobuchwephesha obukhoyo kunye nezorhwebo.
Multi core ifayibha fan kwi / fan ngaphandle isixhobo
Uqhagamshelwa njani kwiintsinga ze-multi-core optical fibers kunye neentsinga zakwantu ezingundoqo? Izixhobo ezininzi ezingundoqo zefiber ngaphakathi kunye ne-fan out (i-FIFO) zizixhobo eziphambili zokuphumeza ukudibanisa okusebenzayo phakathi kweentsinga ezininzi ezingundoqo kunye nemigangatho yendlela enye. Okwangoku, kukho iitekhnoloji ezininzi zokuphumeza i-multi-core fiber fan ngaphakathi kunye ne-fan out izixhobo: itekhnoloji edityanisiweyo yetekhnoloji, indlela ye-bundle fiber bundle, itekhnoloji ye-3D ye-waveguide, kunye netekhnoloji ye-space Optics. Ezi ndlela zingentla zonke zineenzuzo zazo kwaye zifanelekile kwiimeko ezahlukeneyo zesicelo.
Multi core fiber MCF fiber optic isidibanisi
Ingxaki yokudibanisa phakathi kwee-multi-core optical fibers kunye ne-single core optical fibers iye yasonjululwa, kodwa ukudibanisa phakathi kwee-multi-core optical fibers kusafuneka kusonjululwe. Okwangoku, i-multi-core optical fibers idibaniswa kakhulu ngokudibanisa i-fusion splicing, kodwa le ndlela nayo inemida ethile, njengobunzima bokwakha obuphezulu kunye nokugcinwa okunzima kwinqanaba elilandelayo. Okwangoku, akukho mgangatho odibeneyo wokuveliswa kwee-multi-core optical fibers. Umenzi ngamnye uvelisa iifiber ze-optical multi-core ezinamalungiselelo angundoqo ahlukeneyo, ubukhulu be-core, i-core spacing, njl., Eyandisa ngokungabonakaliyo ubunzima bokudibanisa phakathi kwee-multi-core optical fibers.
Multi core fiber MCF Hybrid modyuli (esetyenziswa kwi-EDFA optical amplifier system)
Kwi-Space Division Multiplexing (SDM) inkqubo yokuhanjiswa kwe-optical transmission, isitshixo ekufezekiseni umthamo ophezulu, isantya esiphezulu, kunye nokuhanjiswa kwexesha elide lilele ekuhlawuleleni ukulahleka kokudluliselwa kweempawu kwiifibers optical, kunye ne-optical amplifiers zizinto ezibalulekileyo ezingundoqo kule nkqubo. Njengomsebenzi obalulekileyo wokuqhuba ukusetyenziswa kweteknoloji ye-SDM, ukusebenza kwe-SDM fiber amplifiers kubeka ngokuthe ngqo ukwenzeka kwenkqubo yonke. Phakathi kwazo, i-multi-core erbium-doped fiber amplifier (MC-EFA) ibe yinto ebaluleke kakhulu kwiinkqubo zothumelo lweSDM.
Inkqubo ye-EDFA eqhelekileyo iqulunqwe ikakhulu ngamacandelo angundoqo afana ne-erbium-doped fiber (EDF), umthombo wokukhanya wempompo, i-coupler, i-isolator, kunye nesihluzo se-optical. Kwiinkqubo ze-MC-EFA, ukuze kuphunyezwe ukuguqulwa okusebenzayo phakathi kwe-multi-core fiber (MCF) kunye ne-fiber core eyodwa (SCF), inkqubo idla ngokuzisa izixhobo zeFan / Fan out (FIFO). Isisombululo se-EDFA se-fiber multi-core kulindeleke ukuba sidibanise ngokuthe ngqo umsebenzi wokuguqulwa kwe-MCF-SCF kwizinto ezinxulumene ne-optical components (ezifana ne-980 / 1550 WDM, ukufumana i-flattening filter GFF), ngaloo ndlela yenza lula inkqubo yokwakha kunye nokuphucula ukusebenza ngokubanzi.
Ngophuhliso oluqhubekayo lweteknoloji ye-SDM, amacandelo e-MCF Hybrid aya kubonelela ngezisombululo ezisebenzayo kunye nelahleko ephantsi yeamplifier kwiinkqubo zonxibelelwano oluphezulu lwexesha elizayo.
Kulo mxholo, i-HYC iphuhlise izihlanganisi ze-MCF ze-fiber optic ezilungiselelwe ngokukodwa ukudibanisa i-fiber optic ye-multi-core, kunye neentlobo ezintathu ze-interface: uhlobo lwe-LC, uhlobo lwe-FC, kunye nohlobo lwe-MC. Uhlobo lwe-LC kunye nohlobo lwe-FC uhlobo lwe-MCF ye-multi-core fiber optic izixhumi ziye zalungiswa ngokuyinxenye kwaye ziyilwe ngokusekelwe kwizixhumi ze-LC / FC zendabuko, ukulungelelanisa indawo kunye nokugcinwa komsebenzi, ukuphucula inkqubo yokudibanisa ukugaya, ukuqinisekisa utshintsho oluncinci kwilahleko yokufakwa emva kokudibanisa okuninzi, kunye nokutshintshela ngokuthe ngqo iinkqubo ze-fusion splicing ezibizayo ukuze kuqinisekiswe ukusetyenziswa. Ukongeza, i-Yiyuantong iyile isinxibelelanisi esizinikezeleyo se-MC, esinobungakanani obuncinci kunesidibaniso sohlobo lojongano lwemveli kwaye sinokusetyenziswa kwiindawo ezixineneyo.
