Kutshanje, iNokia Bell Labs ibhengeze ukuba abaphandi bayo bamisela irekhodi lehlabathi lelona zinga liphezulu le-single-carrier bitrate kwi-fiber ye-optical mode eyodwa yeekhilomitha ezingama-80, enobuninzi be-1.52 Tbit / s, elingana nokuhambisa i-1.5 yezigidi zeYouTube. iividiyo ngaxeshanye.Iphindwe kane iteknoloji ye-400G yangoku.Le rekhodi yehlabathi kunye nolunye utshintsho lwenethiwekhi ye-optical iya kuphucula ngakumbi amandla akwaNokia okuphuhlisa uthungelwano lwe-5G ukuhlangabezana nedatha, umthamo, kunye neemfuno ze-latency ye-intanethi ye-intanethi ye-intanethi ye-intanethi kunye nokusetyenziswa kwabathengi.
UMarcus Weldon, iGosa eliPhezulu leTekhnoloji yakwaNokia kunye noMongameli weNokia Bell Labs, wathi: “Ukususela ekuvelisweni kwelahleko ephantsi ye-optical fibers kunye nezixhobo zokukhanya ezinxulumeneyo kwiminyaka engama-50 eyadlulayo.Ukususela kwinkqubo yokuqala ye-45Mbit / s kwinkqubo yanamhlanje ye-1Tbit / s, iye yanda amaxesha angaphezu kwama-20,000 kwiminyaka engama-40 kwaye yenza isiseko sento esiyaziyo njenge-Intanethi kunye noluntu lwedijithali.Indima yeNokia Bell Labs ibisoloko ikukucela umngeni kwimida kunye nokuchaza ngokutsha imida enokwenzeka.Irekhodi lethu lamva nje lehlabathi kuphando lwamehlo lingqina kwakhona Siyila uthungelwano olukhawulezayo nolunamandla ngakumbi ukubeka isiseko soguqulo olulandelayo lwemizi-mveliso. 1.52Tbit/s.Le rekhodi isekwe ngokusebenzisa i-brand entsha ye-128Gigasample / i-converter yesibini ekwazi ukuvelisa iimpawu kwireyithi yesimboli ye-128Gbaud, kwaye izinga lolwazi lwesimboli esisodwa lidlula i-6.0 bits / isimboli / i-polarization.Le mpumelelo yaphule irekhodi ye-1.3Tbit/s eyenziwe liqela ngoSeptemba wama-2019.
Umphandi weNokia Bell Labs uDi Che kunye neqela lakhe baye bamisela irekhodi elitsha lezinga ledatha yehlabathi kwiilaser ze-DML.I-laser ye-DML iyimfuneko kwixabiso eliphantsi, izicelo ezikhawulezayo ezifana nokudityaniswa kweziko ledatha.Iqela le-DML liphumelele izinga lokudluliselwa kwedatha ngaphezu kwe-400 Gbit / s kwikhonkco ye-15-km, ukubeka irekhodi yehlabathi.Ukongezelela, abaphandi beNokia Bell
IiLebhu kutshanje zenze ezinye iimpumelelo ezinkulu kwinkalo yonxibelelwano lwe-optical.
Abaphandi u-Roland Ryf kunye neqela le-SDM bagqibe uvavanyo lokuqala lwentsimi usebenzisa iteknoloji ye-space division multiplexing (SDM) kwi-4-core coupled-core fiber ehamba ngeekhilomitha ze-2,000.Uvavanyo lungqina ukuba i-fiber engundoqo edityanisiweyo inokwenzeka ngokobugcisa kwaye inokuhanjiswa okuphezulu kokusebenza, ngelixa igcina umgangatho woshishino we-125um yokudibanisa idiameter.
Iqela lophando elikhokelwa nguRene-Jean Essiambre, uRoland Ryf kunye noMurali Kodialam bazise isethi entsha yeefomathi zokumodareyitha ezinokubonelela ngokuphuculweyo kokuhanjiswa komgca kunye nokungahambelani komgama kumgama we-submarine we-10,000km.Ifomati yothumelo iveliswa yinethiwekhi ye-neural kwaye ingaba ngcono kakhulu kunefomathi yendabuko (QPSK) esetyenziswa kwiinkqubo zentambo zangaphantsi kwamanzi zanamhlanje.
Umphandi uJunho Cho kunye neqela lakhe babonakalise ngovavanyo ukuba kwimeko yonikezelo lwamandla olunyiniweyo, ngokusebenzisa inethiwekhi ye-neural ukukhulisa inzuzo yokubumba isihluzo ukuze kuzuzwe inzuzo, umthamo wenkqubo yentambo yangaphantsi kwamanzi unokongezwa ngama-23%.
INokia Bell Labs izinikele ekuyileni nasekwakheni ikamva leenkqubo zonxibelelwano lwamehlo, iqhubela phambili uphuhliso lwefiziksi, inzululwazi yemathiriyeli, imathematika, isoftware, kunye nobuchwepheshe bokubona ukwenza uthungelwano olutsha oluqhelana nokutshintsha kweemeko, nangaphaya kwemida yanamhlanje .
