5G lag luam, tus neeg nqa khoom ua ntej. Nrog rau kev xa tawm sai ntawm 5G tes hauj lwm, ua ib qho ntawm cov neeg nqa khoom tseem ceeb ntawm tag nrho 5G kev lag luam, qhov kev thov rau 5G fronthaul tes hauj lwm tau dhau los ua muaj zog. Hauv lub caij nyoog 5G, lub xov tooj cua nkag mus rau hauv network feem ntau yog raws li C-RAN architecture, DU tau xa tawm hauv ib qho chaw nruab nrab, thiab ntau AAUs txuas nrog los ntawm fronthaul network. Cov kev daws teeb meem fronthaul uas C-RAN xav txog feem ntau yog optical fiber direct drive, passive WDM thiab active OTN kev daws teeb meem, uas muaj teeb meem xws li kev siv fiber ntau, tsis muaj kev tswj hwm thiab tus nqi siab; Shenzhen HUANET Technology Co., Ltd. tau cog lus los tsim kom muaj 5G fronthaul network zoo, Nws yog thawj zaug los tsim 5G fronthaul semi-active kev daws teeb meem, uas txhim kho kev ntseeg siab ntawm lub network thiab tseem txhim kho kev tswj hwm thiab kev ua haujlwm thiab kev saib xyuas ntawm fronthaul network.

Cov yam ntxwv ntawm qhov kev pab cuam
Txhawb CPRI 1 ~ 10 thiab eCPRI (10G / 25G), sib xws nrog STM-1/4/16/64, GE / 10GE / 25GE thiab lwm yam kev pabcuam sib koom ua ke, kev sib kis pob tshab, ua kom muaj txiaj ntsig zoo tshaj plaws ntawm fronthaul network
Kev teeb tsa modular, 1: 6/12/18 xaiv tau, tuaj yeem ua tiav ntau txoj kev sib sau ua ke ntau theem, txuag tau fiber ntau
Muaj ntau yam xim teeb pom kev zoo, txhawb nqa CWDM 18 nthwv dej, MWDM 12 nthwv dej, thiab ua tau raws li ntau yam kev xav tau ntawm cov peev nyiaj siv hluav taws xob.
Txhawb kev tiv thaiv txheej txheem optical 1: 1, lub sijhawm hloov pauv tiv thaiv tsawg dua 50ms, txhim kho kev ntseeg siab ntawm network
Txhawb kev tswj hwm network graphical interface, rov tsim kho cov wireless thiab kev tswj hwm kev sib kis, thiab paub txog kev saib xyuas tag nrho ntawm cov khoom siv kho qhov muag thiab kab xwm txheej
Cov khoom siv WDM nquag ntawm chaw ua haujlwm hauv nruab nrab txhawb nqa AC 220V thiab DC -48V kev xaiv fais fab, 1 + 1 kev tiv thaiv fais fab nkag, thiab cov khoom siv fais fab tsis ua haujlwm tsis cuam tshuam rau kev xa khoom lag luam.
WDM passive nyob deb muaj peev xwm xa tawm sab nraum zoov thiab qhov chaw xa tawm yooj yim
Daim ntawv thov scenario
Feem ntau ua tau raws li qhov xav tau ntawm qhov kawg ntawm qhov taw tes-rau-taw tes CRAN networking scenarios, qhov deb ntawm DU thiab AAU qhov chaw yog nyob rau hauv 10km
Hauv cov cheeb tsam uas cov khoom siv fiber ntau optical tsis tshua muaj, tsis muaj cov khoom siv pipeline, thiab cov fiber ntau optical tshiab raug tso tsis muaj kev txwv.
Tsim kom muaj lub network fronthaul zoo los txhawb nqa 5G kev lag luam uas muaj kev ntseeg siab siab
