Ngophuhliso olukhawulezileyo lwetekhnoloji yobukrelekrele bokwenziwa (AI), imfuno yokucubungula idatha kunye namandla onxibelelwano ifikelele kwinqanaba elingazange libonwe ngaphambili. Ingakumbi kwiinkalo ezifana nohlalutyo lwedatha enkulu, ukufunda okunzulu, kunye ne-cloud computing, iinkqubo zonxibelelwano zinemfuno eziphezulu kakhulu zesantya esiphezulu kunye ne-bandwidth ephezulu. Ifayibha yendlela enye yendabuko (i-SMF) ichaphazeleka ngumda weShannon ongengomgca, kwaye amandla ayo okudlulisela aya kufikelela kumda wayo ophezulu. Itekhnoloji yokudlulisela yeSpatial Division Multiplexing (SDM), emelwe yifayibha enee-core ezininzi (i-MCF), isetyenziswa kakhulu kwiinethiwekhi zokudlulisela ezihambelanayo zomgama omde kunye neenethiwekhi zokufikelela kwe-optical ezimfutshane, nto leyo ephucula kakhulu amandla okudlulisela enethiwekhi.
Iifayibha ze-optical ezininzi ezingundoqo ziphula imida yeefayibha zemveli zemo enye ngokuhlanganisa ii-cores ezininzi ezizimeleyo zefayibha kwifayibha enye, nto leyo eyandisa kakhulu amandla okudlulisa. Ifayibha eqhelekileyo ene-core ezininzi inokuba nee-cores ezine ukuya kwezisibhozo zemo enye ezisasazwe ngokulinganayo kwisheya yokukhusela enobubanzi obumalunga ne-125um, nto leyo eyandisa kakhulu amandla e-bandwidth iyonke ngaphandle kokwandisa ububanzi bangaphandle, nto leyo ebonelela ngesisombululo esifanelekileyo sokuhlangabezana nokukhula okukhulu kweemfuno zonxibelelwano kubukrelekrele bokwenziwa.
Ukusetyenziswa kweefayibha ze-optical ezinee-core ezininzi kufuna ukusombulula uthotho lweengxaki ezifana noqhagamshelwano lweefayibha ezinee-core ezininzi kunye nonxibelelwano phakathi kweefayibha ezinee-core ezininzi kunye neefayibha zemveli. Kubalulekile ukuphuhlisa iimveliso ezinxulumene ne-peripheral ezifana nezihlanganisi zefayibha ze-MCF, izixhobo zokungena kunye nokukhupha ifeni ukuze kuguqulwe i-MCF-SCF, kwaye kuqwalaselwe ukuhambelana kunye nokuxhaphaka kweetekhnoloji ezikhoyo nezezorhwebo.
Isixhobo sokufaka/ukukhupha ifeni yefayibha esisiseko ezininzi
Ungazidibanisa njani iifayibha ze-optical ezine-core ezininzi kunye neefayibha ze-optical zendabuko ze-single core? Izixhobo ze-multi core fiber fan in and fan out (FIFO) zizinto ezibalulekileyo zokufezekisa ukudibana okusebenzayo phakathi kweefayibha ze-multi-core kunye neefayibha ze-single-mode eziqhelekileyo. Okwangoku, kukho ubuchwepheshe obuninzi bokusebenzisa izixhobo ze-multi-core fiber fan in and fan out: ubuchwepheshe obuhlanganisiweyo obuhlanganisiweyo, indlela ye-bundle fiber bundle, iteknoloji ye-3D waveguide, kunye neteknoloji ye-space optics. Zonke ezi ndlela zingasentla zineengenelo zazo kwaye zifanelekile kwiimeko ezahlukeneyo zokusetyenziswa.
Isinxibelelanisi sefayibha ye-MCF ye-fiber optic esisiseko se-multi-core
Ingxaki yonxibelelwano phakathi kweefayibha ze-optical ezininzi kunye neefayibha ze-optical ze-single core isonjululwe, kodwa unxibelelwano phakathi kweefayibha ze-optical ezininzi lusafuna ukusonjululwa. Okwangoku, iifayibha ze-optical ezininzi ziqhagamshelwe kakhulu yi-fusion splicing, kodwa le ndlela ikwanazo nemida ethile, njengobunzima obukhulu bokwakha kunye nokugcinwa okunzima kwinqanaba lokugqibela. Okwangoku, akukho mgangatho udibeneyo wokuveliswa kweefayibha ze-optical ezininzi. Umenzi ngamnye uvelisa iifayibha ze-optical ezininzi ezinezicwangciso ezahlukeneyo ze-core, ubungakanani be-core, isithuba se-core, njl.njl., nto leyo enyusa ngokungabonakaliyo ubunzima be-fusion splicing phakathi kweefayibha ze-optical ezininzi.
Imodyuli ye-MCF Hybrid enefayibha eyintloko emininzi (esetyenziswa kwinkqubo ye-EDFA optical amplifier)
Kwinkqubo yokudlulisa i-optical ye-Space Division Multiplexing (SDM), isitshixo sokufikelela kudluliselo olunamandla aphezulu, olukhawulezayo, nolude luxhomekeke ekuhlawuleni ukulahleka kodluliselo lwemiqondiso kwiifayibha ze-optical, kwaye ii-optical amplifiers zizinto ezibalulekileyo kule nkqubo. Njengendlela ebalulekileyo yokuqhuba ukusetyenziswa kobuchwepheshe be-SDM, ukusebenza kwee-SDM fiber amplifiers kumisela ngokuthe ngqo ukuba kunokwenzeka na yonke inkqubo. Phakathi kwazo, i-multi-core erbium-doped fiber amplifier (MC-EFA) ibe yinxalenye ebalulekileyo ebalulekileyo kwiinkqubo zokudlulisa i-SDM.
Inkqubo eqhelekileyo ye-EDFA yenziwe ikakhulu zizinto eziphambili ezifana ne-erbium-doped fiber (EDF), umthombo wokukhanya kwepompo, i-coupler, i-isolator, kunye ne-optical filter. Kwiinkqubo ze-MC-EFA, ukuze kufezekiswe ukuguqulwa okusebenzayo phakathi kwe-multi-core fiber (MCF) kunye ne-single core fiber (SCF), inkqubo idla ngokuzisa izixhobo ze-Fan in/Fan out (FIFO). Isisombululo se-EDFA se-multi-core fiber esizayo kulindeleke ukuba sidibanise ngokuthe ngqo umsebenzi wokuguqulwa kwe-MCF-SCF kwiinxalenye ze-optical ezinxulumene nazo (ezifana ne-980/1550 WDM, i-gain flattening filter GFF), ngaloo ndlela yenza lula uyilo lwenkqubo kwaye iphucule ukusebenza ngokubanzi.
Ngophuhliso oluqhubekayo lwetekhnoloji ye-SDM, izixhobo ze-MCF Hybrid ziya kubonelela ngezisombululo ze-amplifier ezisebenzayo neziphantsi kwiinkqubo zonxibelelwano lwe-optical ezinomthamo ophezulu kwixesha elizayo.
Kule meko, i-HYC iphuhlise izihlanganisi ze-fiber optic ze-MCF ezenzelwe ngokukodwa uqhagamshelo lwe-fiber optic olune-core ezininzi, ezineentlobo ezintathu zojongano: uhlobo lwe-LC, uhlobo lwe-FC, kunye nohlobo lwe-MC. Izihlanganisi ze-fiber optic zohlobo lwe-LC kunye nohlobo lwe-FC ze-MCF ezininzi zitshintshiwe kwaye zayilwa ngokuyinxenye ngokusekelwe kwizihlanganisi ze-LC/FC zemveli, ziphucula umsebenzi wokubeka kunye nokugcina, ziphucula inkqubo yokudibanisa, ziqinisekisa utshintsho oluncinci ekulahlekelweni kokufakwa emva kokudibanisa okuninzi, kwaye zithatha indawo ngokuthe ngqo kwiinkqubo zokudibanisa ezibizayo ukuqinisekisa ukuba kulula ukuzisebenzisa. Ukongeza, i-Yiyuantong ikwayile isihlanganisi se-MC esizinikeleyo, esinobukhulu obuncinci kunezihlanganisi ze-interface zemveli kwaye singasetyenziswa kwiindawo ezixineneyo ngakumbi.
