Daim ntawv thov cov xwm txheej ntawm 5g rau pem hauv ntej xa khoom xws li optical fiber ncaj qha kev sib txuas, wavelength faib multiplexing thiab lwm yam kev siv tshuab sib kis. Ntawm lawv, WDM thev naus laus zis tuaj yeem sib txuam ntau lub yoj yob hauv ib qho fiber ntau. Qhov zoo tag nrho yog qhov peev xwm loj thiab txuag cov khoom siv fiber ntau, tab sis qhov tsis zoo yog tus nqi siab thiab cov peev nyiaj txuas loj. Nws tuaj yeem faib ua ntu zus rau passive WDM, ib nrab ntawm WDM thiab nquag WDM.
Hauv thawj theem ntawm 5g xa mus, kev xa mus rau yav tom ntej feem ntau yuav yog los ntawm kev kho qhov muag ncaj qha ncaj qha kev sib txuas thiab kev ntsuas siab WDM. Nyob rau hauv lub neej yav tom ntej, nrog kev nthuav dav zuj zus ntawm kev sib koom tes sib faib network, tshwj xeeb tshaj yog cov teev thov ntawm cran me nruab nrab thiab qhov nruab nrab nruab nrab kev xa tawm hom, qhov kev faib ua feem ntawm ib nrab WDM yuav muaj ntau ntxiv.
5g' s thov rau kev ua haujlwm siab thiab qis tus nqi kho qhov muag txuas ntxiv mus txuas ntxiv. Kev tsim thev naus laus zis thiab kev tsim khoom saw hlau yog ob txoj hauv kev. Kev nce qib thiab nqes dej ntawm txoj saw kev lag luam thiab txhua tus neeg koom nrog kev lag luam yuav tsum tau tsim kev sib koom ua ke. Raws li kev txheeb xyuas cov ntaub ntawv thov kev thov tiag tiag thiab qhov yuav tsum tau xa mus deb, kev hais kom meej meej, kev siv hluav taws xob thiab kev lag luam hauv ib cheeb tsam yuav tsum tau tsim, thiab qhov tseem ceeb yuav tsum raug txhawb nqa los ntawm cov yam ntxwv ntawm cov qauv thiab cov kev qhia tshwj xeeb, kuaj kev kuaj xyuas thiab ntsuas kev soj ntsuam.
Kev loj hlob sai ntawm 5g kev tsim kho network tau coj cov hauv kev thiab lub sijhawm tseem ceeb rau kev lag luam kho qhov muag khoom siv. Nws cia siab tias cov kev sib txuam thiab kev tsim kho ntawm 5g optical module diversified technology daws teeb meem yuav txuas ntxiv nyob rau hauv lub sijhawm luv luv. Yog tias muaj ntau ceg ntoo, teeb meem xws li kev tsim kho dua tshiab, cov cuab yeej siv khib nyiab thiab kev ua lag luam tawg lag luam yuav tau nqa tuaj, uas yuav cuam tshuam rau kev sib koom tes tsim kho kev lag luam hauv ib qhov twg.
Txhawm rau kom muaj qhov tsawg tshaj plaws ntawm kev cuam tshuam ntawm cov kev daws teeb meem, nws tau hais tias 5g xa mus rau cov kev lag luam txuas ntxiv yuav tsum xav txog kev xa mus ua haujlwm, kev xa mus zoo rau kev ua haujlwm, kev tsim kho qis, kev ua haujlwm yooj yim thiab tswj kev tswj hwm, thiab kev txhim kho benign ntawm kev lag luam saw, ntxiv dag zog rau kev sib koom tes. ntawm cov thev naus laus zis los ntawm cov txheej txheem qib, koom siab ua ke ntawm kev tswj hwm thiab kev tswj tus qauv thiab kev ua haujlwm tswj kev ua haujlwm thiab kev saib xyuas (OAM) mechanism, thiab ntxiv kom zoo dua qub thiab txhim kho kev tsim qauv kev lag luam kev tsim qauv ua kom cov khoom siv kev lag luam raug faib kom nruj, thiab tus nqi tuaj yeem txo qis los ntawm cov nplai nyhuv.
