Pamwambo wa CIOE2019, otsogola otsogola ku China media optical fiber pa intaneti komanso malo ofufuza zamakampani olumikizana nawo adatulutsa mwalamulo "5G zida zotumizira zisanachitike komanso makina opanga makina opanga zinthu zatsopano" pepala loyera. chidwi kwambiri.Chifukwa chidzabweretsa phindu lalikulu lazachuma, mpikisano padziko lonse lapansi ukukulirakulira.Dziko likuthamangira ku tsogolo la 5G ndi liwiro losayerekezeka ndi chilakolako.Ku Korea, yomwe ili yoyamba kugulitsa 5G, ntchito ndi mtengo wamtengo wapatali wa ma modules optical okhudzana ndi makampani opanga zida zakwera kwambiri.Chifukwa cha izi, makampani opanga mauthenga padziko lonse lapansi ayika chiyembekezo chachikulu pa kutumizidwa kwa 5G.Komabe, kuyambira pokonzekera koyambirira ndi kutumizidwa kwa malonda a 5G, makamaka ku South Korea, pali madera ambiri omwe sakudziwika bwino za kufunika kwa 5G pre-transmission. mapulani.Mayankho awa ali ndi cholinga "chokonzanso" zinthu zomwe zilipo (monga PON ndi OTN), kapena kutsata mbali imodzi ya chizindikiro china ndikunyalanyaza kukhudzika kwakukulu kwa mtengo (monga wopanda mtundu komanso wosavuta) Kukhoza), kapena kungonyalanyaza. kusiyana kofunikira pakati pa osalakwa ndi backhaul, ndikubwezeretsanso ophunzira aukadaulo mu network pre-transmission network (monga SPN ndi IPRAN) .Cholinga cha pepala loyerali ndikuwonetsa zida zoyenera ndi opanga ma module.Pepala loyera ili likusanthula mwatsatanetsatane zofunikira za zofunikira zatsopano za netiweki yoyambira: mawonekedwe oyambilira a 25Gbit/s eCPRI ndi zotsatira za gawo la ntchito ya 5G RAN, chomwe ndi chofunikira chapadera mkati mwa netiweki yoyamba, ndipo sichitumiza zazikulu. kuthamanga kwa mphamvu pakati / backhaul.Kulumikizana kwachindunji kwa point-to-point ndiko kukhazikitsidwa kothandiza kwambiri kwa kulumikizana wandiweyani komwe kumafunikira kuti 5G AAU itumizidwe mozama;Kulumikizana kwachindunji kwa point-to-point ndichinthu chosapeŵeka cha ultra-low latency, DU coordination, ndi CU cloud development.
Pepala loyerali limafotokoza za mfundo zogwirira ntchito zamaluso osiyanasiyana omwe amazindikiridwa ndi makampani omwe angagwiritsidwe ntchito pa netiweki yapaintaneti, ndikusanthula mozama ndikufanizira zabwino ndi zoyipa zawo, ndikupereka momveka bwino zosankha zitatu:
The 25Gbit/s pre-transmission granularity ndi zofunika zowonekera mwachindunji zimapangitsa sub-wavelength multiplexing convergence kuthekera kwa OTN wosanjikiza magetsi kusafunikira.Mawonekedwe a mzere wa 100G OTN amatha kupeza njira za 4 zokha za 25Gbit / s.Chifukwa chake, zida za OTN zimagwiritsidwa ntchito mu netiweki ya pre-transmission.Sikoyenera kandulo.
WDM-PON's colorless Optical module ndi adaptive wavelength ukadaulo sangapewe zotchinga zaukadaulo komanso kukakamiza kwa mtengo wa tunability wavelength.Ntchito ya TDM ya WDM-PON yotayidwa imangogwiritsa ntchito ntchito ya ODN ndipo siili yosiyana ndi yankho la WDM lopanda pake, kotero ilibe phindu lothandiza.
Mosiyana ndi zimenezi, teknoloji ya WDM ndi chitsanzo cha kufananitsa koyenera kwa teknoloji yayikulu-granularity, kutumiza kosavuta, unyolo wokhwima wa mafakitale ndi kukhazikitsa kosavuta.Chifukwa chake, ukadaulo wa WDM ndiye chisankho chabwino kwambiri chapaintaneti yakutsogolo kuti athe kuthana ndi kuchepa kwa fiber pamtengo wotsika.
Pepala loyera ili likufuna kuchepetsa mtengo wotumizira pre-network ndikupulumutsa kugwiritsa ntchito fiber.Ndi cholinga cha“yofananira bwino, yayikulu, yosavuta kugwiritsa ntchito, yosavuta kukhazikitsa, ndi yosavuta kukhazikitsa”, pepala loyera ili limapereka mankhwala othamanga kwambiri a Optical module ndi WDM pre-transmission equipment.Maupangiri ambiri amtengo wapatali a R&D ndi oyenera kuwerengedwa mosamala ndi zida zonse ndi opanga ma module.
Njira yabwino yodziwira zam'tsogolo ndikupanga tsogolo.Pepala loyerali lidzakuchotserani chifunga chaumisiri, kumveketsa kafufuzidwe ndi chitukuko cha ma module optical ndi zida zopatsirana zisanachitike, yang'anani pa njira yayikulu yopangira zida zotumizira ma netiweki, ndikuthandizira bwino kutumizidwa kwa malonda a 5G ndi pre- kutumiza ma network.
Pepala loyera ili lalembedwa ndi oitanidwa akuluakulu a 5G ndi akatswiri olankhulana owoneka bwino.Cholinga cha R&D ndi dipatimenti yogulitsa zida zonse zoyankhulirana zowunikira komanso opanga ma module opanga zinthu, komanso ogwira ntchito ku dipatimenti yopangira zisankho.Amamvetsetsa zofunikira zoyankhulirana za 5G zokhudzana ndi kulumikizana ndikuzindikira zinthu zolumikizana ndi 5G zolumikizirana.Kuwongolera kwa R & D, fotokozerani zofunikira za kusamvetsetsana koyenera.
