I-5G yezentengiselwano, umthwali kuqala. Ngokusetshenziswa okusheshayo kwamanethiwekhi e-5G, njengenye yezinkampani eziyisisekelo zomkhakha wonke we-5G, isidingo samanethiwekhi e-fronthaul e-5G siya siqina. Esikhathini se-5G, inethiwekhi yokufinyelela umsakazo isekelwe kakhulu kusakhiwo se-C-RAN, i-DU isetshenziswa ngendlela ephakathi, futhi ama-AAU amaningi axhunywe ngenethiwekhi ye-fronthaul. Izixazululo ze-fronthaul ezicatshangelwa yi-C-RAN ikakhulukazi yi-optical fiber direct drive, i-passive WDM kanye nezixazululo ze-OTN ezisebenzayo, ezinezinkinga ezifana nokusetshenziswa kwemithombo ye-fiber ephezulu, akukho ukulawula kanye nezindleko eziphezulu; i-Shenzhen HUANET Technology Co., Ltd. izibophezele ekwakheni inethiwekhi ye-fronthaul esezingeni eliphezulu ye-5G, Ingowokuqala ukwethula isixazululo se-fronthaul semi-active semi-active semi-active semi-activity semi-activity semi-activity semi-activity semi-action ...

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 ye-fronthaul
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.
Sekela ukuvikelwa kwesendlalelo sokubona esingu-1:1, isikhathi sokushintsha ukuvikelwa singaphansi kwama-50ms, okuthuthukisa ukuthembeka kwenethiwekhi
Isekela ukuphathwa kwenethiwekhi yesibonisi esibonakalayo, yakha kabusha izizinda zokuphathwa okungenantambo kanye nokudluliselwa, futhi iqaphela ukuqapha okugcwele kwemojula yokukhanya kanye nesimo somugqa.
Imishini ye-WDM esebenzayo ehhovisi eliphakathi isekela izinketho zokuphakelwa kukagesi ze-AC 220V kanye ne-DC -48V, ukuvikelwa kokufakwa kwamandla kwe-1+1, futhi ukwehluleka kukagesi kwemishini akuthinti ukudluliswa kwebhizinisi.
I-WDM engasebenzi ekude inamakhono okufaka ngaphandle kanye nezindawo zokufaka eziguquguqukayo
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.
Yakha inethiwekhi yokuhambisa phambili esezingeni eliphezulu ukuze isekele izidingo zebhizinisi ezithembekile ze-5G
