I-5G yorhwebo, umthwali kuqala. Ngokusetyenziswa ngokukhawuleza kweenethiwekhi ze-5G, njengenye yezithuthi ezisisiseko kulo lonke ishishini le-5G, imfuno yeenethiwekhi ze-5G fronthaul iya isiba namandla. Kwixesha le-5G, inethiwekhi yokufikelela kwirediyo isekelwe kakhulu kuyilo lwe-C-RAN, i-DU isetyenziswa ngendlela ephakathi, kwaye ii-AAU ezininzi ziqhagamshelwe ngenethiwekhi ye-fronthaul. Izisombululo ze-fronthaul ezijongwa yi-C-RAN ikakhulu zii-optical fiber direct drive, i-WDM engasebenziyo kunye nezisombululo ze-OTN ezisebenzayo, ezineengxaki ezifana nokusetyenziswa kwezixhobo ze-fiber ephezulu, akukho lawulo kunye neendleko eziphezulu; iShenzhen HUANET Technology Co., Ltd. izibophelele ekwakheni inethiwekhi ye-fronthaul ye-5G esemgangathweni ophezulu, Yeyokuqala ukuqalisa isisombululo se-fronthaul semi-active semi-active semi-5G, esiphucula ukuthembeka kwenethiwekhi kwaye siphucula nolawulo kunye nokusebenza kunye nokugcinwa kwenethiwekhi ye-fronthaul.

Iimpawu zenkqubo
Inkxaso ye-CPRI 1 ~ 10 kunye ne-eCPRI (10G / 25G), iyahambelana ne-STM-1/4/16/64, i-GE / 10GE / 25GE kunye nezinye iinkonzo ezininzi ezihlangeneyo, uthumelo olucacileyo, ukwandisa ixabiso lenethiwekhi ye-fronthaul
Uqwalaselo lweModular, oluyi-1:6/12/18 olukhethwayo, lunokufezekisa ukuhlangana kwamanqanaba amaninzi, ukonga ifayibha enkulu
Iindidi ngeendidi zeemodyuli zokukhanya ezinemibala zinokubonelelwa, ezixhasa amaza e-CWDM 18, amaza e-MWDM 12, kwaye zihlangabezana neemfuno ezahlukeneyo zesalathisi sebhajethi yamandla omgca
Xhasa ukhuseleko lwe-optical layer 1: 1, ixesha lokutshintsha ukhuseleko lingaphantsi kwe-50ms, nto leyo ephucula ukuthembeka kwenethiwekhi
Ixhasa ulawulo lwenethiwekhi yemizobo, yakha kwakhona iidomeyini zolawulo lwe-wireless kunye ne-transmission, kwaye iqaphela ngokupheleleyo ukubekwa esweni kwemodyuli ye-optical kunye nesimo somgca.
Izixhobo ze-WDM ezisebenzayo kwi-ofisi ephakathi zixhasa ukhetho lombane lwe-AC 220V kunye ne-DC -48V, ukhuseleko lokufaka umbane lwe-1+1, kwaye ukusilela kombane kwezixhobo akuchaphazeli ukuhanjiswa kweshishini.
I-WDM engasebenziyo ekude inezakhono zokusasazwa ngaphandle kunye neendawo zokusasazwa eziguquguqukayo
Imeko yesicelo
Ngokuyintloko ukuhlangabezana neemfuno zeemeko zonxibelelwano ze-CRAN eziqala kwindawo enye ukuya kwenye, umgama phakathi kweendawo ze-DU kunye ne-AAU ungaphakathi kwe-10km
Kwiindawo apho izixhobo zefayibha ye-optical zinqongophele khona, akukho zixhobo zemibhobho, kwaye iifayibha ezintsha ze-optical zifakwa ngaphandle kwemiqathango.
Yakha inethiwekhi yokuhambisa impahla esemgangathweni ophezulu ukuxhasa iimfuno zeshishini ezithembekileyo ze-5G
