Nyob rau lub sijhawm ntawm CIOE2019, tus thawj coj kev sib txuas lus kho qhov muag Suav xov xwm kho qhov muag fiber ntau online thiab koom nrog chord kev lag luam tshawb fawb chaw ua haujlwm tau tshaj tawm "5G cov khoom siv ua ntej kis tau tus mob thiab kho qhov muag module khoom tsim kho thiab kev tsim kho tshiab" daim ntawv dawb. Txij li thaum yug los ntawm 5G, nws tau nyiam. ntau xim. Vim tias nws yuav ua rau muaj txiaj ntsig kev lag luam loj, kev sib tw thoob ntiaj teb tau nce zuj zus. Lub ntiaj teb tab tom maj mus rau lub neej yav tom ntej ntawm 5G nrog qhov tsis tau pom dua qhov nrawm thiab mob siab rau.Hauv Kaus Lim Kauslim, uas yog thawj zaug ua lag luam 5G, kev ua haujlwm thiab cov nqi ntawm cov khoom siv kho qhov muag thiab cov tuam txhab lag luam tau nce siab. Vim li no, kev lag luam kev sib txuas lus kho qhov muag thoob ntiaj teb tau tso kev cia siab zoo rau kev xa tawm 5G. Txawm li cas los xij, los ntawm kev npaj ua ntej thiab kev xa mus ua lag luam ntawm 5G, tshwj xeeb tshaj yog nyob rau hauv kev coj ua ntawm Kaus Lim Qab Teb, tseem muaj ntau qhov chaw uas tsis meej meej txog qhov kev thov rau 5G ua ntej kis tau tus mob.Cov tswv lag luam hauv tsev tseem tau npaj ntau yam 5G ua ntej kis tau tus mob. kev npaj. Cov kev daws teeb meem no yog rau lub hom phiaj ntawm "kev rov ua dua tshiab" cov khoom uas twb muaj lawm (xws li PON thiab OTN), lossis ib sab kev nrhiav ntawm ib qho kev taw qhia thiab tsis quav ntsej lub siab rhiab heev rau tus nqi (xws li tsis muaj xim thiab tunable), lossis tsuas yog tsis quav ntsej. qhov tseem ceeb sib txawv ntawm cov dawb huv thiab cov backhaul, thiab muab rov qab rau cov tub ntxhais kawm txuj ci nyob rau hauv lub pre-transmission network (xws li SPN thiab IPRAN).Lub hom phiaj ntawm daim ntawv dawb no yog los qhia cov khoom siv thiab module manufacturers. Daim ntawv dawb no tshuaj xyuas kom meej txog cov yam ntxwv tseem ceeb ntawm cov kev xav tau tshiab ntawm preamble network: 25Gbit / s eCPRI preamble interface yog qhov tshwm sim ntawm 5G RAN kev ua haujlwm segmentation, uas yog qhov tshwj xeeb yuav tsum tau nyob hauv lub preamble network, thiab nws tsis kis loj. muaj peev xwm siab rau nruab nrab / backhaul. Point-to-point pob tshab kev sib txuas ncaj qha yog qhov ua tau zoo tshaj plaws ntawm kev sib txuas ntom ntom uas xav tau rau 5G AAU ntom xa tawm; point-to-point pob tshab kev sib txuas ncaj qha yog qhov yuav tsum tau muaj rau ultra-low latency, DU kev sib koom tes, thiab CU huab kev loj hlob.
Daim ntawv dawb no qhia txog cov qauv kev ua haujlwm ntawm ntau yam kev lag luam-pom zoo cov kev daws teeb meem uas tuaj yeem siv rau hauv kev sib txuas ua ntej kev sib txuas lus, thiab ua tiav kev tshuaj xyuas thiab sib piv lawv qhov zoo thiab qhov tsis zoo, thiab qhia meej txog peb txoj kev xaiv:
Lub 25Gbit / s ua ntej kis tau tus mob granularity thiab pob tshab ncaj qha kev sib txuas yuav tsum ua rau sub-wavelength multiplexing convergence muaj peev xwm ntawm OTN hluav taws xob txheej redundant. 100G OTN kab interface tsuas tuaj yeem nkag mus rau 4 raws ntawm 25Gbit / s cov cim. Yog li ntawd, cov khoom siv OTN yog siv hauv kev sib txuas ua ntej. Tsis tsim nyog lub tswm ciab.
WDM-PON's tsis muaj xim tsis muaj xim kho qhov muag module thiab kev hloov kho wavelength thev naus laus zis tsis tuaj yeem zam kev cuam tshuam kev lag luam thiab tus nqi siab ntawm wavelength tunability. TDM kev ua haujlwm ntawm qhov muab pov tseg WDM-PON tsuas yog siv ODN muaj nuj nqi thiab tsis txawv ntawm qhov kev daws teeb meem WDM, yog li nws tsis muaj txiaj ntsig zoo.
Hauv qhov sib piv, WDM thev naus laus zis yog ib qho piv txwv ntawm kev sib txuam zoo ntawm cov tshuab loj-granularity, kev xa tawm yooj yim, cov saw hlau loj thiab kev siv yooj yim. Yog li ntawd, WDM thev naus laus zis yog qhov kev xaiv zoo tshaj plaws rau pem hauv ntej kev sib kis network kom kov yeej qhov tsis txaus ntawm cov khoom siv fiber ntau ntawm tus nqi qis..
Daim ntawv dawb no yog txhawm rau txo tus nqi xa tawm ntawm lub vev xaib ua ntej thiab txuag kev siv fiber ntau. Nrog lub hom phiaj ntawm“Kev sib txuam zoo, loj-loj, yooj yim-rau-deploy, yooj yim rau kev siv, thiab siv tau yooj yim”, daim ntawv dawb no qhia cov khoom siv kho qhov muag ceev ceev thiab WDM cov khoom siv ua ntej kis tau tus mob. Ntau cov lus qhia muaj txiaj ntsig R & D kev tsim kho tshiab tsim nyog nyeem kom zoo los ntawm txhua yam khoom siv thiab cov tuam txhab tsim khoom.
Txoj hauv kev zoo tshaj los kwv yees yav tom ntej yog tsim lub neej yav tom ntej. Daim ntawv dawb no yuav tshem tawm cov pos huab rau koj, qhia meej txog kev tshawb fawb thiab kev loj hlob ntawm cov khoom siv kho qhov muag thiab cov khoom siv ua ntej kis tau tus mob, tsom mus rau cov channel tseem ceeb ntawm cov khoom siv sib txuas ua ntej sib txuas, thiab txhawb nqa 5G kev lag luam xa mus thiab ua ntej. kev tsim kho network.
Daim ntawv dawb no yog sau los ntawm cov neeg raug caw 5G thiab cov kws tshaj lij kev sib txuas lus kho qhov muag. Nws yog tsom rau ntawm R & D thiab kev muag khoom ntawm tag nrho cov khoom siv sib txuas lus kho qhov muag thiab cov khoom tsim kho qhov muag, thiab cov neeg ua haujlwm cuam tshuam ntawm lub tuam txhab kev txiav txim siab. Lawv nkag siab txog 5G ntsig txog kev sib txuas lus kho qhov muag thiab txiav txim siab 5G ntsig txog kev sib txuas lus kho qhov muag khoom. R & D kev taw qhia, qhia meej cov ntaub ntawv tsim nyog txog kev nkag siab yuam kev.
