I-5G yokuthengisa, ophethe kuqala.Ngokusheshisa ukuthunyelwa kwamanethiwekhi e-5G, njengenye yezinkampani eziyisisekelo zemboni yonke ye-5G, isidingo samanethiwekhi we-5G fronthaul siya siba namandla.Esikhathini se-5G, inethiwekhi yokufinyelela yomsakazo isekelwe ikakhulukazi ekwakhiweni kwe-C-RAN, i-DU isetshenziswa ngendlela ephakathi nendawo, futhi ama-AAU amaningi axhunywe ngenethiwekhi ye-fronthaul.Izixazululo ze-fronthaul ezicatshangelwa yi-C-RAN ngokuyinhloko ziyi-fiber optical drive direct drive, i-WDM engenzi lutho kanye nezixazululo ezisebenzayo ze-OTN, ezinezinkinga ezifana nokusetshenziswa okuphezulu kwe-fiber resource, akukho ukulawula kanye nezindleko eziphezulu;I-Shenzhen HUANET Technology Co., Ltd. izibophezele ekwakheni inethiwekhi yekhwalithi ephezulu ye-5G fronthaul, Iqala ukwethula isisombululo se-semi-active se-5G fronthaul, esithuthukisa ukuthembeka kwenethiwekhi futhi siphinde sithuthukise ukuphathwa nokusebenza nokugcinwa. yenethiwekhi ye-fronthaul.

Izici zohlelo
Sekela i-CPRI 1~10 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 ye-fronthaul
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.
Sekela isendlalelo se-optical 1: ukuvikelwa kwe-1, isikhathi sokushintsha ukuvikela singaphansi kwama-50ms, sithuthukisa ukuthembeka kwenethiwekhi
Isekela ukuphathwa kwenethiwekhi ye-graphical interface, yakha kabusha izizinda zokuphatha ezingenantambo nezidluliswayo, futhi ibona ukuqapha okugcwele kwe-optical module kanye nesimo somugqa
Imishini esebenzayo ye-WDM ehhovisi elimaphakathi isekela izinketho zokuphakelwa kwamandla ka-AC 220V kanye ne-DC -48V, ukuvikela okokufaka kwamandla okungu-1+1, futhi ukwehluleka kwamandla kwemishini akuthinti ukuhanjiswa kwebhizinisi.
I-WDM ye-remote passive inamandla okuthunyelwa ngaphandle nezindawo zokuphakela eziguquguqukayo
Isimo sohlelo lokusebenza
Ihlangabezana kakhulu nezidingo zezimo zenethiwekhi ze-CRAN, ibanga eliphakathi kwezindawo ze-DU ne-AAU lingaphakathi kwe-10km.
Ezindaweni lapho izinsiza zefiber optical ziyindlala, azikho izinsiza zamapayipi, futhi imicu emisha ye-optical ibekwa ngaphandle kwemibandela.
Yakha inethiwekhi ye-fronthaul yekhwalithi ephezulu ukuze usekele izidingo zebhizinisi ezinokwethenjelwa okuphezulu kwe-5G
