Esikhathini se-5G, inethiwekhi engenantambo isebenzisa imodi yokwakha isayithi le-C-RAN, kanti i-DU isetshenziswa ngendlela ephakathi nendawo.
Ezinye izindawo ezikude ze-5G zizobekwa ndawonye nezindawo ezikude ze-4G ezikhona. Kunesidingo esiphuthumayo sokufakwa kweziteshi eziyisisekelo ezimbozwe ngokujulile, futhi kukhona ikhambi lokufakwa kwe-fiber direct drive front haul. Kukhona uchungechunge lwezinkinga ezifana nokusetshenziswa okukhulu kwezinsizakusebenza ze-optical fiber kanye nobunzima bokukhula. Njengomhlinzeki wesevisi yesisombululo esisodwa sokuxhumana kwe-optical, i-Shenzhen HUANET Technology Co., Ltd. yethule ikhambi le-5G front haul passive WDM ngale njongo.
Izici zohlelo
Sekela i-CPRI 1 ~ 10 kanye ne-eCPRI (10G/25G), iyahambisana ne-STM-1/4/16/64, i-GE/10GE/25GE kanye nezinye izinsizakalo eziningi ezihlanganisiwe, ukudluliselwa okusobala, kukhulisa inani lenethiwekhi yokuthutha yangaphambili.
Ngaphandle kokushintsha isakhiwo senethiwekhi, ukwandisa isiteshi esibonakalayo sokudlulisa okusobala okumsulwa, ngaphandle kokwethula ukubambezeleka kanye nokushaqeka
Ukucushwa kwe-Modular, okungakhethwa okungu-1:6/12/18, kungafinyelela ukuhlangana kwamazinga amaningi, ukonga ifayibha enkulu
Kunganikezwa amamojula ahlukahlukene okukhanya okunemibala, asekela amagagasi e-CWDM 18, amagagasi e-MWDM 12, futhi ahlangabezana nezidingo zesabelomali samandla emigqa ehlukahlukene.
Indawo yokusebenza emsulwa, enciphisa amaphuzu okwehluleka, i-plug and play, akukho ukucushwa, ukulungiswa okulula
I-multiplexer ye-passive wavelength division incane futhi ilula, futhi isekela izindlela eziningi zokufaka ezifana nokufakwe ku-rack, okufakwe odongeni, okufakwe ezinsikeni, njll.
Isimo sohlelo lokusebenza
Ngokuyinhloko kuhlangabezana nezidingo zezimo zokuxhumana ze-CRAN ezisuka endaweni eyodwa ziye kwenye, ibanga eliphakathi kwezindawo ze-DU ne-AAU lingaphakathi kwamakhilomitha ayi-10
Ezindaweni lapho izinsiza ze-optical fiber zimbalwa khona, azikho izinsiza zepayipi futhi kufakwa izintambo ezintsha ze-optical ngaphandle kwemibandela.
Uma kunqunyelwe isikhathi sokwakha, kungasetshenziswa njengesixazululo esiphuthumayo ukuxazulula inkinga yefayibha okwesikhashana
