Munguva pfupi yadarika, Nokia Bell Labs yakazivisa kuti vaongorori vayo vakaisa rekodhi pasi rose yepamusoro-soro-inotakura bit rate pane yakajairwa single-mode optical fiber yemakiromita makumi masere, ine huwandu hunosvika 1.52 Tbit/s, iyo yakaenzana nekufambisa miriyoni imwe nemazana mashanu eYouTube. mavhidhiyo panguva imwe chete.Iyo yakapetwa kane iyo ikozvino 400G tekinoroji.Iri rekodhi renyika uye humwe hutsva hwekuona network huchawedzera kugona kweNokia kuvandudza 5G network kuti isangane nedata, huwandu, uye latency zvinodiwa zveindasitiri yeInternet yezvinhu uye kushandiswa kwevatengi.
Marcus Weldon, Chief Technology Officer weNokia uye Mutungamiriri weNokia Bell Labs, akati: "Kubva pakatanga kugadzirwa kwemafiber akaderera-akarasikirwa uye ane hukama hwemagetsi makore makumi mashanu apfuura.Kubva pakutanga 45Mbit/s system kusvika kune yanhasi 1Tbit/s system, Yakawedzera kanopfuura ka20,000 mumakore makumi mana uye yakagadzira hwaro hwezvatinoziva seInternet uye nzanga yedhijitari.Basa reNokia Bell Labs ragara riri rekupikisa miganhu uye kutsanangura patsva miganhu inokwanisika.Rekodhi yedu yazvino yepasi rose mukutsvagisa kwemaziso inoratidza zvakare kuti Tiri kugadzira network dzinokurumidza uye dzine simba rekuisa hwaro hweshanduko yeindasitiri inotevera. ”Nokia Bell Labs Optical Network Research Group inotungamirwa naFred Buchali yakagadzira imwechete inotakura chiyero chekusvika. 1.52Tbit/s.Iyi rekodhi inotangwa nekushandisa brand new 128Gigasample/second converter iyo inogona kugadzira masaini pachiyero chechiratidzo che128Gbaud, uye chiyero cheruzivo chechiratidzo chimwe chinodarika 6.0 bits/symbol/polarization.Kubudirira uku kwakatyora rekodhi 1.3Tbit/s yakagadzirwa nechikwata munaGunyana 2019.
Nokia Bell Labs muongorori Di Che nechikwata chake vakaisawo rekodhi rekodhi redhisheni yenyika yeDML lasers.DML lasers yakakosha kune yakaderera-mutengo, yakakwirira-kumhanya maapplication senge data center connections.Chikwata cheDML chakawana mwero wekufambiswa kwedata unopfuura 400 Gbit/s pamusoro peiyo 15-km link, ichiisa rekodhi pasi rose. Pamusoro pezvo, vaongorori veNokia Bell.
Labs ichangobva kuita zvimwe zvakakura zvakabudirira mumunda we optical communications.
Vatsvagiri Roland Ryf nechikwata cheSDM vakapedza bvunzo yekutanga vachishandisa space division multiplexing (SDM) tekinoroji pane 4-core coupled-core fiber inotora 2,000 makiromita.Kuedza kunoratidza kuti coupling core fiber inogoneka nehunyanzvi uye ine yakanyanya kutapurirana kuita, uku ichichengetedza indasitiri yakajairwa 125um cladding dhayamita.
Chikwata chekutsvagisa chinotungamirwa naRene-Jean Essiambre, Roland Ryf naMurali Kodialam chakaunza seti nyowani yemafomati ekugadzirisa iyo inogona kupa yakagadziridzwa mutsara uye isiri-mutsara wekutapurirana dhizaini chinhambwe che10,000km.Iyo fomati yekufambisa inogadzirwa neneural network uye inogona kuve irinani zvakanyanya kupfuura yechinyakare fomati (QPSK) inoshandiswa mune yanhasi submarine cable system.
Muongorori Junho Cho nechikwata chake vakaratidza kuburikidza nezviyedzo kuti kana paine magetsi mashoma, nekushandisa neural network kukwenenzvera kuwana kuumba sefa kuti uwane kugona, kugona kweiyo submarine cable system inogona kuwedzerwa ne23%.
Nokia Bell Labs yakatsaurirwa kugadzira nekuvaka remangwana remagetsi ekutaurirana masisitimu, kufambisa kuvandudzwa kwefizikisi, zvesainzi sainzi, masvomhu, software, uye tekinoroji yekuona kuti igadzire network nyowani dzinoenderana nekuchinja kwemamiriro, uye kure nemiganhu yanhasi.
