Esikhathini se-5G, inethiwekhi engenantambo ngokuyisisekelo yamukela imodi yokwakha isayithi ye-C-RAN, futhi i-DU isetshenziswa ngendlela emaphakathi.
Ezinye izingosi ezikude ze-5G zizohlanganiswa nezingosi ezikude ze-4G ezikhona.Kunesidingo esiphuthumayo sokwakhiwa kwangaphambili kweziteshi zesisekelo ezinokufakwa okujulile, futhi isisombululo se-fiber direct drive front hul sikhona.Kukhona uchungechunge lwezinkinga ezifana nokusetshenziswa kakhulu kwezinsiza ze-fiber optical kanye nobunzima ekwandiseni.Njengomhlinzeki wesevisi yesisombululo esisodwa-stop kwezokuxhumana zamehlo, i-Shenzhen HUANET Technology Co., Ltd. yethule isixazululo se-5G sokudonsa ngaphambili se-WDM sale njongo.
Izici zohlelo
Sekela i-CPRI 1~10 kanye ne-eCPRI (10G/25G), ehambisana ne-STM-1/4/16/64, GE/10GE/25GE kanye nezinye izithwali ezihlanganisiwe zezinsizakalo eziningi, ukudluliswa okusobala, kukhulisa inani lenethiwekhi yokudonsa ngaphambili
Ngaphandle kokushintsha isakhiwo senethiwekhi, ukwandisa ishaneli ebonakalayo yokudlulisela okusobala okumsulwa, ngaphandle kokwethula ukubambezeleka kanye ne-jitter
Ukucushwa kwe-Modular, 1:6/12/18 ngokuzikhethela, kungafinyelela ukuhlangana okuneziqondiso eziningi kwamaleveli amaningi, ukonga ifayibha ngezinga elikhulu
Izinhlobonhlobo zamamojula okukhanya kombala zinganikezwa, zisekela amaza e-CWDM 18, amaza e-MWDM 12, futhi zihlangabezane nezidingo zenkomba yebhajethi yesabelomali samandla ehlukene.
Indawo yokusebenza ehlanzekile, enciphisa amaphuzu okuhluleka, ipulaki nokudlala, akukho ukucushwa, ukulungiswa okulula
I-passive wavelength division multiplexer incane futhi ilula, futhi isekela izindlela zokufaka eziningi ezifana ne-rack efakwe, efakwe odongeni, i-pole-mounted, njll.
Isimo sohlelo lokusebenza
Ihlangabezana kakhulu nezidingo zezimo zenethiwekhi ze-CRAN, ibanga eliphakathi kwezindawo ze-DU ne-AAU lingaphakathi kwe-10km.
Ezindaweni lapho izinsiza ze-optical fibre ziyindlala khona, azikho izinsiza zamapayipi futhi ama-optical fibers amasha abekwe ngaphandle kwemibandela.
Uma kunqunyelwe isikhathi sokwakha, kungasetshenziswa njengesixazululo esiphuthumayo ukuxazulula inkinga yefayibha okwesikhashana
