I-5G yorhwebo, umthwali kuqala.Ngokuthunyelwa ngokukhawuleza kweenethiwekhi ze-5G, njengomnye wabathwali abasisiseko kwi-industry ye-5G yonke, imfuno ye-5G ye-fronthaul networks iqina ngakumbi.Ngexesha le-5G, inethiwekhi yokufikelela kwirediyo isekelwe ikakhulu kwi-architecture ye-C-RAN, i-DU isetyenziswe ngendlela ephakathi, kwaye ii-AAU ezininzi zixhunyiwe nge-intanethi ye-fronthaul.Izixazululo ze-fronthaul ezicatshangelwa yi-C-RAN ziyi-fiber optical drive direct drive, i-WDM engabonakaliyo kunye nezisombululo ze-OTN ezisebenzayo, ezineengxaki ezifana nokusetyenziswa kwe-fiber ephezulu, akukho lawulo kunye neendleko eziphezulu;I-Shenzhen HUANET Technology Co., Ltd. izimisele ukwakha inethiwekhi ye-5G ye-fronthaul ephezulu, Yeyokuqala ukusungula isisombululo se-5G fronthaul semi-active, esiphucula ukuthembeka kwenethiwekhi kunye nokuphucula ulawulo kunye nokusebenza kunye nokugcinwa. yenethiwekhi yangaphambili.

Iimpawu zenkqubo
Inkxaso ye-CPRI 1 ~ 10 kunye ne-eCPRI (10G/25G), ehambelana ne-STM-1/4/16/64, GE/10GE/25GE kunye nezinye iinkonzo ezininzi ezidibeneyo, ukuhanjiswa okucacileyo, ukwandisa ixabiso lenethiwekhi ye-fronthaul
Ulungelelwaniso lweModyuli, i-1: 6/12/18 ngokukhetha, inokufikelela kwi-multi-directional multi-level convergence, ukugcinwa kwefiber enkulu
Iimodyuli ezahlukeneyo zokukhanya kombala zinokubonelelwa, zixhasa amaza e-CWDM 18, amaza e-MWDM 12, kunye nokuhlangabezana neemfuno zesalathiso sebhajethi yombane ohlukeneyo.
Inkxaso ye-optical layer 1: ukhuseleko lwe-1, ixesha lokutshintsha ukhuseleko lingaphantsi kwe-50ms, ukuphucula ukuthembeka kwenethiwekhi
Ixhasa ulawulo lwenethiwekhi yojongano lwegraphical, yakha kwakhona imimandla yolawulo engenazingcingo kunye nothumelo, kwaye iqonda iliso elipheleleyo lemodyuli yokubona kunye nenqanaba lomgca.
Izixhobo ze-WDM ezisebenzayo kwi-ofisi ephakathi zixhasa i-AC 220V kunye ne-DC -48V iinketho zobonelelo lwamandla, i-1 + 1 yokukhusela igalelo lamandla, kunye nokusilela kombane wesixhobo akuchaphazeli ukuhanjiswa kweshishini.
I-WDM ye-Remote passive inamandla okusasaza ngaphandle kunye neendawo eziguquguqukayo zokusasazwa
Imeko yesicelo
Ikakhulu ukuhlangabezana neemfuno zokuphela kwendawo-to-point iimeko zenethiwekhi ze-CRAN, umgama phakathi kwe-DU kunye neendawo ze-AAU ungaphakathi kwe-10km.
Kwiindawo apho izibonelelo zefiber optical zinqongopheleyo, akukho zixhobo zemibhobho, kwaye iifiber zamehlo ezintsha zibekwe ngaphandle kwemiqathango.
Yakha inethiwekhi ye-fronthaul esemgangathweni ophezulu ukuxhasa iimfuno zezoshishino ezithembekileyo ze-5G
