Muva nje, iNokia Bell Labs imemezele ukuthi abacwaningi bayo baqophe irekhodi lomhlaba ngenani eliphakeme kakhulu le-bit yenkampani yenethiwekhi eyodwa ku-fiber optical yemodi eyodwa ejwayelekile yamakhilomitha angu-80, enesilinganiso esiphezulu esingu-1.52 Tbit/s, okulingana nokudlulisa izigidi ezingu-1.5 ze-YouTube. amavidiyo ngesikhathi esifanayo.Kuphindwe kane kunobuchwepheshe bamanje be-400G.Leli rekhodi lomhlaba kanye nokunye okuqanjwe kabusha kwenethiwekhi yokubona kuzothuthukisa ikhono leNokia lokuthuthukisa amanethiwekhi e-5G ukuze ahlangabezane nedatha, umthamo, kanye nezidingo zokubambezeleka ze-inthanethi yezimboni kanye nezinhlelo zokusebenza zabathengi.
U-Marcus Weldon, Isikhulu Esiyinhloko Sezobuchwepheshe kwaNokia kanye noMongameli weNokia Bell Labs, uthe: “Kusukela kwasungulwa ama-optical fibers alahleka kancane kanye nemishini yokubona ehlobene eminyakeni engu-50 edlule.Kusukela ohlelweni lokuqala lwe-45Mbit/s kuya ohlelweni lwanamuhla lwe-1Tbit/s, Inyuke izikhathi ezingaphezu kuka-20,000 eminyakeni engu-40 futhi yakha isisekelo salokho esikwazi njenge-inthanethi kanye nomphakathi wedijithali.Indima yeNokia Bell Labs bekulokhu kuwukubekela inselele imikhawulo kanye nokuchaza kabusha imikhawulo engenzeka.Irekhodi lethu lakamuva lomhlaba ocwaningweni lwamehlo liyafakazela futhi ukuthi Sisungula amanethiwekhi asheshayo nanamandla ngokwengeziwe ukubeka isisekelo soguquko oluzayo lwezimboni.” INokia Bell Labs Optical Network Research Group eholwa uFred Buchali idale i-bit rate eyodwa efinyelela ku- 1.52Tbit/s.Leli rekhodi lisungulwa kusetshenziswa i-128Gigasample/isiguquli sesibili esisha sha esingakhiqiza amasiginali ngesilinganiso sophawu esingu-128Gbaud, futhi izinga lolwazi lophawu olulodwa lidlula amabhithi angu-6.0/uphawu/ukuhlukaniswa.Le mpumelelo yephule irekhodi le-1.3Tbit/s elakhiwe iqembu ngoSepthemba 2019.
Umcwaningi wakwaNokia Bell Labs u-Di Che nethimba lakhe baphinde baqopha irekhodi elisha lezinga ledatha yomhlaba wonke lama-laser e-DML.Amalaser e-DML abalulekile ezinhlelweni zokusebenza ezishibhile, ezinesivinini esikhulu njengokuxhumeka kwesikhungo sedatha.Ithimba le-DML lizuze izinga lokudluliswa kwedatha elingaphezu kuka-400 Gbit/s ngesixhumanisi esingamakhilomitha angu-15, okwenza irekhodi lomhlaba. Ngaphezu kwalokho, abacwaningi bakwaNokia Bell
Amalebhu asanda kwenza ezinye izimpumelelo ezinkulu emkhakheni wezokuxhumana ngokukhanya.
Abacwaningi u-Roland Ryf kanye nethimba le-SDM baqedele ukuhlola kwenkundla yokuqala kusetshenziswa ubuchwepheshe be-space division multiplexing (SDM) ku-4-core coupled-core fiber ehlanganisa amakhilomitha angu-2,000.Ukuhlolwa kufakazela ukuthi i-coupling core fiber iyenzeka ngobuchwepheshe futhi inamandla okudlulisela phambili ukusebenza, kuyilapho kugcinwa izinga lembonini lobubanzi obuyi-125um cladding.
Ithimba labacwaningi eliholwa u-Rene-Jean Essiambre, u-Roland Ryf kanye noMurali Kodialam lethule isethi entsha yamafomethi wokuguquguquka angahlinzeka ngokusebenza okuthuthukisiwe kokudluliswa kwemigqa nokungewona omugqa ebangeni elingaphansi kolwandle elingu-10,000km.Ifomethi yokudlulisela ikhiqizwa inethiwekhi ye-neural futhi ingaba ngcono kakhulu kunefomethi evamile (i-QPSK) esetshenziswa kumasistimu ekhebula angaphansi kolwandle.
Umcwaningi u-Junho Cho nethimba lakhe bafakazele ngokuhlolwa ukuthi esimweni sokuphakelwa kwamandla alinganiselwe, ngokusebenzisa inethiwekhi ye-neural ukuze kuthuthukiswe isihlungi sokwakheka kwenzuzo ukuze kuzuzwe umthamo, umthamo wesistimu yamakhebula angaphansi kolwandle angakhuliswa ngo-23%.
INokia Bell Labs izinikele ekuklameni nasekwakheni ikusasa lezinhlelo zokuxhumana ngokubona, iqhubekisela phambili ukuthuthukiswa kwefiziksi, isayensi yezinto ezibonakalayo, izibalo, isofthiwe, nobuchwepheshe bokubona ukuze bakhe amanethiwekhi amasha avumelana nezimo ezishintshayo, nangaphezu kwemingcele yanamuhla .
