Ngexesha le-5G, inethiwekhi engenazintambo ithatha ngokusisiseko i-C-RAN imodi yokwakha indawo, kwaye i-DU isetyenziswe ngendlela ephakathi.
Ezinye iisayithi ezikude ze-5G ziya kufakwa kunye neendawo ezikhoyo ezikude ze-4G.Kukho imfuno engxamisekileyo yokwakhiwa kwezikhululo ezisisiseko ezinokhuselo olunzulu, kunye nefiber direct drive front haul solution ikhona.Kukho uluhlu lweengxaki ezifana nokusetyenziswa okunzulu kwezixhobo zefiber optical kunye nobunzima ekwandiseni.Njengomboneleli wenkonzo yesisombululo esisodwa sonxibelelwano lwe-optical, i-Shenzhen HUANET Technology Co., Ltd. uye wasungula isisombululo se-5G sangaphambili se-WDM sokwenza le njongo.
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 yokuthuthwa kwangaphambili
Ngaphandle kokutshintsha isakhiwo sothungelwano, ukwandisa itshaneli ebonakalayo yosasazo olusulungekileyo, ngaphandle kokwazisa ukulibaziseka kunye nejitter.
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.
Indawo yokusebenza ecocekileyo, ukunciphisa amanqaku angaphumeleli, iplagi kunye nokudlala, akukho lungelelwaniso, ukugcinwa okulula
I-multiplexer yolwahlulo lwe-wavelength incinci kwaye ilula, kwaye ixhasa iindlela ezininzi zokufakela ezifana ne-rack enyusiweyo, exhonywe eludongeni, exhonywe ipali, njl.
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 ezintsha zamehlo zibekwe ngaphandle kwemiqathango.
Xa kukhawulelwe lixesha lokwakha, linokusetyenziswa njengesisombululo esingxamisekileyo ukusombulula okwethutyana ingxaki yefiber
