Mugihe cya CIOE2019, itumanaho rya optique ryitumanaho ryitangazamakuru ryubushinwa optique fibre kumurongo hamwe n’ikigo cy’ubushakashatsi cy’inganda za chord cyasohoye ku mugaragaro “ibikoresho bya 5G mbere yo kohereza hamwe n’ibikoresho bya optique biteza imbere no guhanga udushya” impapuro zera. Kuva havuka 5G, imaze gukurura kwitabwaho cyane. Kuberako bizazana inyungu nini mubukungu, amarushanwa ku isi agenda arushaho gukomera. Isi irihuta mugihe kizaza cya 5G ifite umuvuduko nishyaka bitigeze bibaho.Muri Koreya, niyambere mugucuruza 5G, imikorere nigiciro cyimigabane ya modulike optique hamwe nibigo byibikoresho byazamutse. Kubera iyo mpamvu, inganda zitumanaho za optique ku isi zashyize ibyiringiro byinshi ku kohereza 5G. Icyakora, guhera mu igenamigambi hakiri kare no kohereza ubucuruzi bwa 5G, cyane cyane mu bikorwa bya Koreya y'Epfo, haracyari uduce twinshi tutarasobanuka neza ku cyifuzo cya 5G mbere yo kohereza.Abakozi bo mu gihugu kinini na bo basabye ko hajyaho 5G mbere yo kohereza gahunda. Ibi bisubizo nibigamije "kuvugurura" ibicuruzwa biriho (nka PON na OTN), cyangwa gukurikirana uruhande rumwe rukurikirana icyerekezo runaka no kwirengagiza ibyiyumvo bihanitse kubiciro (nkibara ritagira ibara kandi rihinduka) Ubushobozi), cyangwa kwirengagiza gusa itandukaniro ryingenzi hagati yinzirakarengane ninyuma, hanyuma usubize inyuma abanyeshuri biga tekinike murusobekerane rwambere (nka SPN na IPRAN) .Intego yuru rupapuro rwera nukwerekana ibikoresho bijyanye nabakora module. Uru rupapuro rwera rusesengura mu buryo burambuye ibintu byingenzi biranga ibisabwa bishya byurusobe rwibanze: Imigaragarire ya 25Gbit / s eCPRI ni ibisubizo byibikorwa bya 5G RAN, ibyo bikaba aribyo bisabwa bidasanzwe imbere y'urusobekerane, kandi ntirwohereza runini imbaraga zubushobozi hagati / gusubira inyuma. Guhuza ingingo-ku-mucyo mu buryo butaziguye ni uburyo bwiza bwo gushyira mu bikorwa imiyoboro yuzuye isabwa kuri 5G AAU yuzuye; Ingingo-ku-ngingo-mucyo mu buryo butaziguye ni byanze bikunze bisabwa kugirango ultra-low latence, guhuza DU, hamwe niterambere rya CU.
Uru rupapuro rwera rusobanura amahame yimirimo yinganda zinyuranye zemewe zishobora gukemurwa muburyo bwa tekiniki zishobora gukoreshwa murusobekerane rwambere, kandi rusesengura byimazeyo kandi rugereranya ibyiza byabo nibibi, kandi rusobanura neza amahitamo atatu:
25Gbit / s mbere yo kwanduza granularité hamwe nibisabwa mu buryo butaziguye bisabwa bituma sub-wavelength multiplexing ihuza ubushobozi bwa OTN amashanyarazi atagabanuka. Imigaragarire ya 100G OTN irashobora kugera kumiyoboro 4 gusa ya 25Gbit / s. Kubwibyo, ibikoresho bya OTN bikoreshwa murusobe rwambere. Ntabwo bikwiye buji.
Moderi ya WDM-PON idafite ibara rya optique hamwe na tekinoroji ya adaptive ya tekinoroji ntishobora kwirinda inzitizi za tekiniki hamwe nigitutu cyigiciro cyumurambararo. Imikorere ya TDM ya WDM-PON yajugunywe ikoresha gusa imikorere ya ODN kandi ntaho itandukaniye nigisubizo cya WDM gusa, ntabwo rero ifite agaciro keza.
Ibinyuranye, tekinoroji ya WDM ni urugero rwo guhuza neza ikoranabuhanga rinini-rinini, uburyo bworoshye, urwego rukuze rukuze kandi rushyirwa mubikorwa byoroshye. Kubwibyo, tekinoroji ya WDM niyo ihitamo ryiza kumurongo wohereza imbere kugirango utsinde ibura ryumutungo wa fibre ku giciro gito.
Uru rupapuro rwera rugamije kugabanya ibiciro byoherejwe mbere yumurongo no kuzigama imikoreshereze ya fibre. Nintego ya“guhuza neza, binini-binini, byoroshye-kubohereza, byoroshye kubishyira mubikorwa, kandi byoroshye kubishyira mubikorwa”, iyi mpapuro yera yerekana ibicuruzwa byihuta bya optique module nibikoresho bya WDM mbere yo kohereza. Ibyerekezo byinshi byingenzi bya R&D bishya bikwiye gusomwa neza nibikoresho byose bijyanye nabakora module.
Inzira nziza yo guhanura ibizaza ni ugushiraho ejo hazaza. Uru rupapuro rwera ruzahanagura igihu cya tekiniki kuri wewe, risobanure icyerekezo cyubushakashatsi niterambere ryicyerekezo cya optique hamwe nibikoresho byabanjirije kohereza, byibanda kumuyoboro nyamukuru wibicuruzwa byoherejwe mbere yo kohereza, kandi bishyigikire neza kohereza ibicuruzwa 5G no kubanziriza- kubaka imiyoboro.
Uru rupapuro rwera rwanditswe nabatumirwa bakuru 5G ninzobere mu itumanaho rya optique. Igamije ishami R&D nogurisha ibikoresho byose byitumanaho rya optique hamwe nabashinzwe gutunganya ibicuruzwa bya optique, hamwe nabakozi bireba ishami rishinzwe gufata ibyemezo. Basobanukiwe nibisabwa na 5G byitumanaho ryitumanaho kandi bagena ibicuruzwa byitumanaho bya 5G bijyanye. Icyerekezo R & D, sobanura amakuru akenewe kubyerekeye kutumva neza.
