5G yamalonda, wonyamula patsogolo. Ndi kufalikira mwachangu kwa maukonde a 5G, monga imodzi mwa zonyamulira zoyambira zamakampani onse a 5G, kufunikira kwa maukonde a 5G fronthaul kukukulirakulira. Mu nthawi ya 5G, netiweki yolumikizira wailesi imadalira kwambiri kapangidwe ka C-RAN, DU imagwiritsidwa ntchito m'njira yapakati, ndipo ma AAU angapo amalumikizidwa kudzera mu netiweki ya fronthaul. Mayankho a fronthaul omwe C-RAN imaganizira makamaka ndi optical fiber direct drive, passive WDM ndi mayankho a OTN ogwira ntchito, omwe ali ndi mavuto monga kugwiritsa ntchito fiber yambiri, kusakhala ndi ulamuliro komanso mtengo wokwera; Shenzhen HUANET Technology Co., Ltd. yadzipereka kumanga netiweki ya fronthaul yapamwamba kwambiri ya 5G, Ndi yoyamba kuyambitsa yankho la fronthaul semi-active la 5G, lomwe limawongolera kudalirika kwa netiweki komanso limawongolera kuyendetsa bwino ndi kugwiritsa ntchito ndi kusamalira netiweki ya fronthaul.

Zinthu za pulogalamu
Thandizani CPRI 1 ~ 10 ndi eCPRI (10G/25G), imagwirizana ndi STM-1/4/16/64, GE/10GE/25GE ndi zina zonyamula zinthu zambiri, transmission yowonekera bwino, komanso kukulitsa kufunika kwa netiweki ya fronthaul.
Kapangidwe ka modular, 1:6/12/18 kosankha, kumatha kukwaniritsa kulumikizana kwa magawo ambiri, kupulumutsa ulusi waukulu
Ma module osiyanasiyana a kuwala kwamitundu angaperekedwe, othandizira mafunde a CWDM 18, mafunde a MWDM 12, komanso kukwaniritsa zofunikira zosiyanasiyana za bajeti yamagetsi.
Thandizani chitetezo cha kuwala kwa gawo 1:1, nthawi yosinthira chitetezo ndi yochepera 50ms, zomwe zimapangitsa kuti maukonde akhale odalirika
Imathandizira kasamalidwe ka netiweki yolumikizirana, imamanganso ma domain owongolera opanda zingwe ndi ma transmission, ndipo imazindikira kuwunika kwathunthu kwa gawo la kuwala ndi momwe mzere ulili.
Zipangizo za WDM zomwe zikugwira ntchito ku ofesi yayikulu zimathandiza njira zamagetsi za AC 220V ndi DC -48V, chitetezo cha magetsi a 1+1, ndipo kulephera kwa magetsi sikukhudza kutumiza kwa bizinesi.
WDM yokhazikika patali ili ndi mphamvu zotumizira kunja komanso malo osinthira otumizira
Chitsanzo cha ntchito
Makamaka kukwaniritsa zosowa za zochitika za CRAN zolumikizirana pakati pa malo a DU ndi AAU zili mkati mwa 10km.
M'madera omwe zinthu zopangira ulusi wa kuwala sizikupezeka, palibe zinthu zopangira mapaipi, ndipo ulusi watsopano wa kuwala umayikidwa popanda malire.
Pangani netiweki yapamwamba kwambiri yothandizira zosowa za bizinesi ya 5G yodalirika kwambiri
