5G kev lag luam, tus neeg nqa khoom ua ntej.Nrog rau kev xa tawm sai ntawm 5G tes hauj lwm, raws li ib qho ntawm cov neeg nqa khoom yooj yim ntawm tag nrho 5G kev lag luam, qhov kev thov rau 5G fronthaul tes hauj lwm tau ua kom muaj zog.Nyob rau hauv lub 5G era, lub xov tooj cua nkag network yog feem ntau raws li lub C-RAN architecture, DU yog deployed nyob rau hauv ib tug centralized yam, thiab ntau AAUs yog txuas nrog lub fronthaul network.Cov kev daws teeb meem pem hauv ntej tau txiav txim siab los ntawm C-RAN feem ntau yog cov khoom siv kho qhov muag ncaj qha tsav, passive WDM thiab nquag OTN cov kev daws teeb meem, uas muaj teeb meem xws li kev siv fiber ntau, tsis muaj kev tswj thiab tus nqi siab;Shenzhen HUANET Technology Co., Ltd. tau cog lus los tsim kom muaj lub siab zoo 5G fronthaul network, Nws yog thawj zaug tso tawm 5G fronthaul semi-active tov, 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.

Program nta
Kev them nyiaj yug CPRI 1 ~ 10 thiab eCPRI (10G / 25G), tau tshaj STM-1/4/16/64, GE/10GE/25GE thiab lwm yam kev pabcuam sib koom ua ke, sib kis tau zoo, ua kom muaj txiaj ntsig ntawm fronthaul network
Modular configuration, 1: 6 / 12 / 18 xaiv tau, tuaj yeem ua tiav ntau txoj kev qhia ntau theem kev sib koom ua ke, loj-teev fiber ntau txuag
Muaj ntau yam xim lub teeb modules tuaj yeem muab tau, txhawb nqa CWDM 18 nthwv dej, MWDM 12 nthwv dej, thiab ua tau raws li ntau yam kab hluav taws xob cov peev txheej kev xav tau
Txhawb optical txheej 1: 1 kev tiv thaiv, kev tiv thaiv hloov lub sijhawm tsawg dua 50ms, txhim kho kev ntseeg siab
Txhawb graphical interface network tswj, reconstructs wireless thiab kis tau tus mob tswj domains, thiab paub tag nrho saib xyuas ntawm optical module thiab kab xwm txheej
Cov khoom siv ua haujlwm WDM ntawm lub hauv paus chaw ua haujlwm txhawb nqa AC 220V thiab DC -48V fais fab mov xaiv, 1 + 1 lub zog tawm tswv yim tiv thaiv, thiab cov khoom siv hluav taws xob tsis ua haujlwm tsis cuam tshuam rau kev lag luam kev sib kis.
Tej thaj chaw deb passive WDM muaj peev xwm xa tawm sab nraud thiab qhov chaw xa tawm yooj yim
Daim ntawv thov scenario
Feem ntau ua tau raws li qhov xav tau ntawm qhov kawg point-to-point CRAN networking scenarios, qhov kev ncua deb ntawm DU thiab AAU qhov chaw yog nyob rau hauv 10km
Nyob rau hauv cov cheeb tsam uas cov khoom siv kho qhov muag tsis tshua muaj, tsis muaj cov peev txheej hauv cov kav dej, thiab cov khoom siv kho qhov muag tshiab tau muab tso rau yam tsis muaj xwm txheej.
Tsim kom muaj qhov zoo tshaj plaws fronthaul network los txhawb 5G kev ntseeg siab ua lag luam xav tau
