Ngesikhathi se-CIOE2019, isikhungo sokucwaninga esihamba phambili se-Chinese media optical fiber online kanye nesikhungo sokucwaninga semboni ye-chord esixhumene sakhulula ngokusemthethweni "imishini ye-5G yangaphambi kokudlulisela kanye nokuthuthukiswa komkhiqizo we-optical module kanye nokuqamba okusha". Kusukela kwazalwa i-5G, iye yaheha ukunakwa okuningi. Ngenxa yokuthi uzoletha izinzuzo ezinkulu kwezomnotho, ukuncintisana emhlabeni wonke kuya ngokuya kushuba. Umhlaba uphuthuma ikusasa le-5G ngejubane elingakaze libonwe nothando.E-Korea, okungeyokuqala ukuthengisa i-5G, ukusebenza kanye nentengo yesitoko yamamojula ahlobene optical kanye nezinkampani zamadivayisi zinyukile. Ngenxa yalokhu, imboni yezokuxhumana emhlabeni wonke ibeke ithemba elikhulu ekusetshenzisweni kwe-5G. Kodwa-ke, kusukela ekuhleleni kokuqala nokuthunyelwa kwezentengiselwano kwe-5G, ikakhulukazi emisebenzini yaseNingizimu Korea, kusenezindawo eziningi ezingakacaci ngokuphelele mayelana nesidingo se-5G pre-transmission.Opharetha abakhulu basekhaya baye bahlongoza ukudluliswa kwangaphambili kwe-5G okuhlukahlukene. izinhlelo. Lezi zixazululo ngezenhloso “yokuvuselela” imikhiqizo ekhona (efana ne-PON ne-OTN), noma ukulandela uhlangothi olulodwa lwenkomba ethile nokunganaki ukuzwela okuphezulu kwezindleko (njengokungakwazi ukumibalabala nokuguqulekayo) noma ukumane uzibe. umehluko obalulekile phakathi kwabamsulwa kanye ne-backhaul, nokubuyisela abafundi bezobuchwepheshe kunethiwekhi yangaphambi kokudluliselwa (njenge-SPN ne-IPRAN).Inhloso yaleli phepha elimhlophe ukukhombisa abakhiqizi bemishini kanye namamojula afanele. Leli phepha elimhlophe lihlaziya ngokuningiliziwe izici ezibalulekile zezidingo ezintsha zenethiwekhi yesandulela: isixhumi esibonakalayo sesandulela se-25Gbit/s eCPRI siwumphumela wokuhlukaniswa komsebenzi we-5G RAN, okuyisidingo esiyingqayizivele ngaphakathi kwenethiwekhi eyandulelayo, futhi ayidluliseli enkulu. ukucindezela komthamo kuya maphakathi/backhaul. Ukuxhumana okuqondile okukhomba iphuzu kuya kwephuzu kuwukuqaliswa okuphumelelayo kakhulu koxhumano oluminyene oludingekayo ekusetshenzisweni okuminyene kwe-5G AAU; ukuxhumeka okuqondile kwe-point-to-point kuyisidingo esingenakugwenywa se-ultra-low latency, i-DU coordination, kanye nokuthuthukiswa kwamafu e-CU.
Leli phepha elimhlophe lichaza izimiso zokusebenza zezixazululo ezihlukahlukene zobuchwepheshe eziqashelwa yimboni ezingasetshenziswa kunethiwekhi yangaphambi kokudlulisa, futhi lihlaziye ngokucophelela futhi liqhathanise izinzuzo nezinkinga zazo, futhi liphakamisa ngokucacile izinketho ezintathu eziqondisayo:
Imbudumbudu ye-25Gbit/s yangaphambi kokudluliswa kanye nezidingo zokuxhuma okuqondile okusobala zenza amandla okuhlangana okuphindaphindeka kwe-wavelength engaphansi kwesendlalelo sikagesi se-OTN angasebenzi. Isixhumi esibonakalayo somugqa we-100G OTN singafinyelela kuphela iziteshi ezi-4 zamasignali angu-25Gbit/s. Ngakho-ke, imishini ye-OTN isetshenziswa kunethiwekhi yangaphambi kokudlulisela. Akufanelekile ikhandlela.
Imojula ye-WDM-PON ye-Optical engenambala kanye nobuchwepheshe be-wavelength obuvumelanayo abukwazi ukugwema izithiyo zobuchwepheshe kanye nokucindezela kwezindleko kokushuthwa kwe-wavelength. Umsebenzi we-TDM we-WDM-PON elahliwe usebenzisa umsebenzi we-ODN kuphela futhi awuhlukile kusixazululo se-WDM esingenzi lutho, ngakho awunalo inani elingokoqobo.
Ngokuphambene, ubuchwepheshe be-WDM buyisibonelo sokumatanisa kahle kobuchwepheshe be-granularity enkulu, ukuthunyelwa okulula, uchungechunge lwezimboni ezivuthiwe kanye nokuqaliswa okulula. Ngakho-ke, ubuchwepheshe be-WDM buyisinqumo esingcono kakhulu senethiwekhi yokudlulisela phambili ukunqoba ukushoda kwezinsiza ze-fiber ngezindleko eziphansi.
Leli phepha elimhlophe lihlose ukwehlisa izindleko zokuphakela zenethiwekhi yangaphambili futhi konga ukusetshenziswa kwefayibha. Ngenhloso ye“ukufanisa okusebenzayo, okukhulu, okulula ukukusebenzisa, kulula ukukusebenzisa, futhi kulula ukukusebenzisa”, leli phepha elimhlophe lihlongoza imikhiqizo yemojula ye-high speed optical kanye nemishini ye-WDM pre-transmission. Izikhombisi-ndlela eziningi ezibalulekile ze-R&D zifanele ukufundwa ngokucophelela yizo zonke izisetshenziswa ezifanele kanye nabakhiqizi bamamojula.
Indlela engcono kakhulu yokubikezela ikusasa ukudala ikusasa. Leli phepha elimhlophe lizosula inkungu yobuchwepheshe kuwe, likucacisele ucwaningo nesiqondiso sokuthuthukiswa kwamamojula we-optical kanye nemishini yangaphambi kokudlulisela, igxile esiteshini esikhulu semikhiqizo yokudlulisa inethiwekhi yangaphambi kokudlulisela, futhi isekele ngempumelelo ukuthunyelwa kwezentengiselwano kwe-5G kanye ne-pre- ukwakhiwa kwenethiwekhi yokudlulisela.
Leli phepha elimhlophe libhalwe ochwepheshe abaphezulu abamenyiwe be-5G kanye ne-optical communication. Ihloselwe umnyango we-R&D nowokuthengisa wazo zonke izinto zokusebenza zokuxhumana nabathuthukisi bomkhiqizo we-optical module, kanye nabasebenzi abafanelekile bomnyango othatha izinqumo wamasu. Baqonda izidingo zokuxhumana eziphathelene ne-5G futhi banqume imikhiqizo yokuxhumana ye-5G ehlobene ne-optical. Isiqondiso se-R & D, cacisa ulwazi oludingekayo mayelana nokungaqondi kahle okufanele.
