Pachiitiko cheCIOE2019, iyo inotungamira yekukurukurirana kweChinese media optical fiber online uye yakabatana chord indasitiri yekutsvagisa yakaburitsa zviri pamutemo "5G pre-transmission equipment uye optical module chigadzirwa kugadzirwa uye innovation" chena bepa.Kubva pakuzvarwa kwe5G, yakwezva kutarisisa kwakawanda.Nokuti zvichaunza zvikomborero zvakakura zvehupfumi, makwikwi pasi rose ari kuramba achiwedzera.Nyika iri kumhanyira kune ramangwana re5G nekumhanya kusati kwamboitika uye nechido.MuKorea, inova yekutanga kutengesa 5G, kuita uye mutengo wemasheya weanoenderana optical module uye makambani emidziyo akakwira.Nekuda kweizvi, indasitiri yepasi rose yekuonana yekuonana yakaisa tariro huru pakutumirwa kwe5G.Zvisinei, kubva pakuronga kwekutanga uye kushandiswa kwekutengeserana kwe5G, kunyanya mukuita kweSouth Korea, kuchine nzvimbo dzakawanda dzisina kunyatsojeka pamusoro pekuda kwe5G pre-transmission. zvirongwa.Mhinduro idzi ndedzechinangwa che "kuvandudza" zvigadzirwa zviripo (sePON neOTN), kana kutsvaga-kudivi rimwe kwechimwe chiratidzo uye kufuratira kunzwisiswa kwakanyanya kudhura (senge isina ruvara uye inogoneka) Kugona), kana kungofuratira. musiyano unokosha pakati pevasina mhosva uye backhaul, uye kudzorera vadzidzi veunyanzvi mu-pre-transmission network (yakadai seSPN uye IPRAN) .Chinangwa chepepa chena iyi kuratidza michina yakakodzera uye vanogadzira module.Iri bepa jena rinoongorora zvakadzama maitiro akakosha ezvitsva zvinodiwa zve preamble network: iyo 25Gbit/s eCPRI preamble interface ndiyo mhedzisiro ye5G RAN basa segmentation, inova ndiyo yakasarudzika inodiwa mukati me preamble network, uye haifambisi yakakura. simba rekumanikidza kusvika pakati / backhaul.Point-to-point transparent direct connection ndiyo inonyanya kushanda yekubatanidza dense inodiwa kuti 5G AAU dense deployment;point-to-point transparent direct connection chinhu chisingadzivisiki chinodiwa che Ultra-low latency, DU coordination, uye CU cloud development.
Iri bepa jena rinodonongodza misimboti yekushanda kweakasiyana indasitiri-anozivikanwa anogona hunyanzvi mhinduro ayo anogona kushandiswa mu-pre-transmission network, uye anoongorora zvizere uye achienzanisa zvakanakira nekuipira kwavo, uye anonyatso kurudzira sarudzo nhatu dzekutungamira:
Iyo 25Gbit/s pre-transmission granularity uye yakajeka yakananga yekubatanidza zvinodiwa zvinoita kuti sub-wavelength multiplexing convergence kugona kweOTN yemagetsi layer ive shoma.Iyo 100G OTN mutsetse interface inogona chete kuwana 4 chiteshi che 25Gbit/s masiginecha.Naizvozvo, iyo OTN michina inoshandiswa mune pre-kutapurirana network.Hazvina kukodzera kenduru.
WDM-PON's colorless optical module uye adaptive wavelength tekinoroji haigone kudzivirira zvipingamupinyi zvehunyanzvi uye mutengo wekumanikidzwa kwewavelength tunability.Iyo TDM basa reyakaraswa WDM-PON rinongoshandisa iyo ODN basa uye haina kusiyana neyakangoita WDM mhinduro, saka haina Practical kukosha.
Kusiyana neizvi, tekinoroji yeWDM muenzaniso wekuenzanisa kwakaringana kwehukuru-granularity tekinoroji, kuendesa kuri nyore, yakakura maindasitiri ketani uye nyore kuita.Naizvozvo, WDM tekinoroji ndiyo yakanakisa sarudzo kune yekumberi yekufambisa network kukunda kushomeka kwefiber zviwanikwa pamutengo wakaderera.
Iri bepa jena rinovavarira kudzikisa mutengo wekutumira weiyo pre-network uye kuchengetedza kushandiswa kwefiber.Nechinangwa che“kunyatsoenderana, hukuru-hukuru, nyore-kuisa, nyore kushandisa, uye nyore kuita”, bepa jena iri rinokurudzira zvigadzirwa zvepamusoro-speed optical module uye WDM pre-transmission equipment.Mazhinji akakosha eR&D ekuvandudza madhairekitori akakodzera kuverenga nekungwarira neakakodzera michina uye module vagadziri.
Nzira yakanaka yekufanotaura nezveramangwana kugadzira ramangwana.Iri bepa jena richakuchenera mhute yehunyanzvi, kujekesa kutsvagisa nekusimudzira kutungamira kweOptical modules uye pre-transmission midziyo, tarisa pane huru chiteshi che pre-transmission network transmission products, uye zvinobudirira kutsigira 5G kushambadzira kwekutengesa uye pre- transmission network kuvaka.
Iri chena bepa rakanyorwa neakakokwa mukuru 5G uye optical communication nyanzvi.Iyo yakanangana neR&D uye dhipatimendi rekutengesa rezvese zvekutaurirana zvekushandisa uye optical module zvigadzirwa vanogadzira, uye vashandi vakakodzera vedhipatimendi rekuita sarudzo.Ivo vanonzwisisa iyo 5G ine chekuita neoptical kutaurirana zvinodiwa uye vanoona iyo 5G ine chekuita nemagetsi ekutaurirana zvigadzirwa.R & D kutungamira, jekesa ruzivo rwakakosha nezve kwakakodzera kusanzwisisa.
