5G Fronthaul Passive WDM Tharollo

Nakong ea 5G, marang-rang a se nang mohala a nka mokhoa oa ho haha ​​​​sebaka sa C-RAN, 'me DU e sebelisoa ka mokhoa o bohareng.

Libaka tse ling tse hole tsa 5G li tla be li kopane le libaka tse hole tsa 4G tse teng.Ho na le tlhokahalo e potlakileng ea forehaul ea liteishene tsa motheo tse nang le tšireletso e tebileng, 'me tharollo ea fiber direct drive front hul e teng.Ho na le letoto la mathata a kang tšebeliso e tebileng ea lisebelisoa tsa fiber optical le bothata ba ho atolosa.E le mofani oa litšebeletso tsa tharollo ea sebaka se le seng bakeng sa puisano ea optical, Shenzhen HUANET Technology Co., Ltd. e hlahisitse tharollo ea 5G ea pele ea haul passive WDM bakeng sa morero ona.

Likarolo tsa lenaneo
Tšehetsa CPRI 1 ~ 10 le eCPRI (10G/25G), e lumellanang le STM-1/4/16/64, GE/10GE/25GE le tse ling tse ngata tse nang le litšebeletso tse ngata tse kopaneng, phetisetso e pepeneneng, e eketsa boleng ba marang-rang a ho hula ka pele.
Ntle le ho fetola sebopeho sa marang-rang, ho holisa mocha oa 'mele oa phetisetso e hlakileng e hlakileng, ntle le ho hlahisa tieho le jitter.
Phetoho ea Modular, 1: 6/12/18 ka boikhethelo, e ka fihlela khokahanyo ea maemo a mangata a fapaneng, poloko ea fiber e kholo.
Ho ka fanoa ka li-module tse fapaneng tsa leseli la mebala, tse tšehetsang maqhubu a CWDM 18, maqhubu a MWDM 12, le ho fihlela litlhoko tse fapaneng tsa index ea tekanyetso ea matla.
Sebaka se hloekileng sa ho sebetsa, se fokotsang lintlha tsa ho hloleha, plug le ho bapala, ha ho na tlhophiso, tlhokomelo e bonolo
The passive wavelength division multiplexer e nyane ebile e bobebe, mme e ts'ehetsa mekhoa e mengata ea ho kenya joalo ka rack e kentsoeng, e kentsoeng leboteng, e phahamisitsoeng ka lipalo, joalo-joalo.

Boemo ba kopo
Haholo-holo e finyella litlhoko tsa maemo a marang-rang a CRAN, sebaka se pakeng tsa libaka tsa DU le AAU se ka hare ho 10km.
Libakeng tseo mehloli ea fiber ea optical e haellang, ha ho na lisebelisoa tsa liphaephe le likhoele tse ncha tsa optical li behiloe ntle le maemo.
Ha e fokotsoa ke nako ea kaho, e ka sebelisoa e le tharollo ea tšohanyetso ho rarolla bothata ba nakoana ka nakoana
