5G yekutengeserana, inotakura zvinhu pakutanga. Nekukurumidza kuendeswa kwemanetwork e5G, seimwe yemakambani makuru e5G, kudiwa kwemanetwork e5G fronthaul kuri kuramba kuchiwedzera. Munguva ye5G, network yeredhiyo inonyanya kuenderana neC-RAN architecture, DU inoshandiswa nenzira yepakati, uye maAAU akawanda akabatana kuburikidza nenetwork yefronthaul. Mhinduro dzefronthaul dzinotariswa neC-RAN dzinosanganisira optical fiber direct drive, passive WDM uye active OTN solutions, dzine matambudziko akadai sekushandiswa kwefiber resource yakawanda, kusadzora uye kudhura kwakanyanya; Shenzhen HUANET Technology Co., Ltd. yakazvipira kuvaka network yefronthaul ye5G yepamusoro, Ndiyo yekutanga kutanga mhinduro yefronthaul ye5G fronthaul semi-active, iyo inovandudza kuvimbika kwenetwork uye zvakare inovandudza manejimendi uye mashandiro uye kuchengetedza network yefronthaul.

Zvinhu zvepurogiramu
Tsigira CPRI 1 ~ 10 uye eCPRI (10G/25G), inoenderana neSTM-1/4/16/64, GE/10GE/25GE nedzimwe nzira dzakawanda dzekutakura dzakabatana, transmission yakajeka, inowedzera kukosha kwenetwork yepamberi
Kugadziriswa kwemodular, 1:6/12/18 sarudzo, kunogona kuita kuti pave nekubatana kwematanho akawanda, kuchengetedza fiber yakawanda
Mamodule akasiyana-siyana emwenje ane mavara anogona kupihwa, anotsigira mafungu eCWDM 18, mafungu eMWDM 12, uye achisangana nezvinodiwa zvakasiyana-siyana zvebhajeti remagetsi emagetsi.
Tsigirai dziviriro ye optical layer 1:1, nguva yekuchinja yekudzivirira isingasviki 50ms, zvichivandudza kuvimbika kwenetwork
Inotsigira manejimendi ye graphical interface network, inovakazve ma domains e wireless uye transmission management, uye inoita kuti pave nekutarisa kwakazara kwe optical module uye line status.
Midziyo yeWDM inoshanda iri muhofisi yepakati inotsigira sarudzo dzemagetsi dzeAC 220V neDC -48V, dziviriro yekupinda kwemagetsi kubva pa1+1, uye kutadza kwemagetsi kwemidziyo hakukanganisi kutapurirana kwebhizinesi.
Remote passive WDM ine kugona kwekuisa zvinhu panze uye nzvimbo dzinochinjika dzekuisa zvinhu
Mamiriro ekushandisa
Zvikurukuru zvinosangana nezvinodiwa zve end point-to-point CRAN networking scenarios, daro riri pakati peDU neAAU sites riri mukati me10km
Munzvimbo dzisina zvinhu zve optical fiber, hapana zvinhu zvepaipi, uye fiber itsva dze optical dzinoiswa pasina miganhu.
Vaka network yepamberi yepamusoro yekutsigira zvinodiwa zvebhizinesi re5G rakavimbika zvakanyanya
