Rau 5G kev lag luam siv, 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 dhau los ua kom muaj zog thiab muaj zog. Nyob rau hauv lub 5G era, lub xov tooj cua nkag network yog feem ntau raws li lub C-RAN architecture, thiab lub DU yog deployed nyob rau hauv ib tug centralized yam, thiab ntau AAUs txuas nrog lub fronthaul network. Cov yam ntxwv tseem ceeb ntawm cov kev pabcuam uas yuav tsum tau muab los ntawm 5G network suav nrog cov bandwidth loj, tsis tshua muaj latency, thiab kev sib txuas loj, uas muab cov kev xav tau tshiab rau cov neeg siv lub network hais txog bandwidth, peev xwm, latency, thiab kev sib txuas yooj yim. Cov tsoos C-RAN 5G bearer network feem ntau yog kev kho qhov muag fiber ntau ncaj qha kev daws teeb meem, uas muaj teeb meem xws li kev siv loj ntawm cov khoom siv fiber ntau, tus nqi siab, thiab kev tswj tsis zoo thiab kev tswj; HTF tau cog lus los tsim kom muaj 5G fronthaul tes hauj lwm zoo, 5G midhaul tes hauj lwm, thiab 5G backhaul Network, HTF launched lub passive wavelength division ntxiv rau xim lub teeb module tov, semi-active OLP tiv thaiv tov,WDM/OTNactive kev daws teeb meem, uas daws qhov loj bandwidth thiab qeeb qeeb yuav tsum tau ntawm 5G bearer network, thiab txhim kho kev ntseeg siab ntawm lub network. Nyob rau tib lub sijhawm, nws tseem txhim kho kev tswj hwm thiab kev ua haujlwm ntawm fronthaul network.
5G Fronthaul Passive WDM Kev daws teeb meem
Program nta:
Los ntawm WDM module, lub wavelength ntawm qhov tau txais thiab txais lub teeb ntawm txhua lub channel yog staggered, thiab cov teeb liab ntawm ntau lub wavelengths tau ua ke rau hauv ib qho fiber ntau rau kev sib kis los ntawm kev siv multiplexer thiab demultiplexer;
Siv rau lub wavelength channels ntawm 1271nm txog 1371nm;
Passive ua haujlwm, tsis muaj cov ntsiab lus tsis ua haujlwm ntxiv, yooj yim rau kev khiav lag luam thiab tswj;
Kev teeb tsa ceev, tsis muaj kev debugging, tsis muaj fais fab mov, ntsaws thiab ua si;
Tau tshaj ntau yam ceev thiab cov kev pab cuam raws tu qauv hauv qab 10G, nrog muaj zog versatility;
OTN-based 5G midhaul / backhaul bearer daws
Txoj kev no sivWDM/OTNkom paub txog 5G fronthaul, midhaul, thiab 5G backhaul, thiab paub txog kev sib sau thiab xa mus ntawm cov kev pabcuam loj;
WDM/OTN ua tau raws li qhov xav tau ntawm 5G bearer rau cov neeg muaj peev xwm loj, thiab ua tau raws li cov kev sib txuas ceev xws li 25GE, 50GE, thiab 100GE qhia los ntawm IPRAN;
Lub multiplexing thiab pob tshab kis tau tus mob ntawm ntau yam kev pab cuam ntawm ntau qhov chaw txuag tau ntau ntawm fiber ntau.
Nws txhawb OAM cov haujlwm xws li txheej txheej kho qhov muag thiab cov txheej txheem hluav taws xob thiab kev kuaj xyuas qhov tsis raug, thiab tuaj yeem muab kev tiv thaiv kev sib txuas los xyuas kom muaj kev ntseeg siab ntawm cov kev pabcuam.
WDM / OTN yog lub tshuab xa hluav taws xob, uas ib txwm muaj cov yam ntxwv ntawm cov bandwidth loj thiab qeeb qeeb, thiab tuaj yeem xa tag nrho cov kev pabcuam tib lub sijhawm nrog qeeb qeeb.
Nws txhawb nqa dual-routing 1 ntxiv rau 1 kev tiv thaiv, thiab cov kev pabcuam yuav tsis cuam tshuam vim lub sijhawm ncua sijhawm sib txawv ntawm txoj hauv kev tseem ceeb thiab thaub qab thaum tiv thaiv kev hloov pauv.
