Kwixesha le-5G, inethiwekhi engenazingcingo ngokusisiseko isebenzisa imo yokwakha indawo ye-C-RAN, kwaye i-DU isetyenziswa ngendlela ephakathi.
Ezinye iindawo ezikude ze-5G ziya kubekwa kwindawo enye neendawo ezikude ze-4G ezikhoyo. Kukho imfuneko engxamisekileyo yokuhanjiswa kwangaphambili kwezikhululo zesiseko ezinesigqubuthelo esinzulu, kwaye kukho isisombululo se-fiber direct drive front haul. Kukho uthotho lweengxaki ezinje ngokusetyenziswa kakhulu kwezixhobo ze-optical fiber kunye nobunzima bokwandiswa. Njengomboneleli wenkonzo yesisombululo esinye sonxibelelwano lwe-optical, iShenzhen HUANET Technology Co., Ltd. iqalise isisombululo se-5G front haul passive WDM kule njongo.
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 yokuthutha ngaphambili.
Ngaphandle kokutshintsha isakhiwo senethiwekhi, ukwandisa itshaneli ebonakalayo yothumelo olucacileyo, ngaphandle kokungenisa ukulibaziseka kunye ne-jitter
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
Indawo yokusebenza ecocekileyo, ukunciphisa amanqaku okusilela, iplagi kunye nokudlala, akukho lungiselelo, ukulungiswa okulula
I-multiplexer ye-passive wavelength division incinci kwaye ilula, kwaye ixhasa iindlela ezininzi zokufakela ezifana ne-rack mounted, i-wall-mounted, i-pole-mounted, njl.
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 ziyafakwa ngaphandle kwemiqathango.
Xa inqunyelwe lixesha lokwakha, ingasetyenziswa njengesisombululo esingxamisekileyo ukusombulula ingxaki yefayibha okwethutyana
