Cov cim qhia sib txawv ：
DWDM thev naus laus zis tsis muaj qauv sib xws. Hauv kev ua haujlwm ntawm kev ua haujlwm, qhov ntev ntawm ib qho teeb meem tsuas yog hloov mus rau qhov sib thooj wavelength hauv kev sib txuas lus hauv network los ntawm lub hloov pauv. Los ntawm kev kho qhov muag thev naus laus zis, qhov kis tau tus mob wavelength yog multiplexed.
OTN muaj tus ncej ua tiav tshuab, yog li nws muaj peev xwm nkag thiab ua kom tiav, thiab txhim kho kev ua tau zoo ntawm kev siv bandwidth.
Cov sib txawv hauv kev sib koom tes thiab kev tiv thaiv cov tshuab ：
Network hom ntawm DWDM thev naus laus zis yog feem ntau taw-rau-kis, saw, lub hnub qub thiab lub nplhaib sib txuas. Hais txog kev tiv thaiv hom, tsuas yog kev tiv thaiv cov nyom los tiv thaiv. Kev tiv thaiv hom yog feem ntau kev tiv thaiv ntawm kev kho qhov muag rov qab, thiab kev tiv thaiv ntawm 1 + 1 thiab 1: 1 yog siv rau ntawm txoj kev kho qhov muag. Lub davhlau ya nyob twg khoom siv tsis tiv thaiv. Hom kev tiv thaiv no yuav tsum tau muaj ob lub kho qhov muag tau hla nws tus kheej. Kev tiv thaiv tus kheej ntawm DWDM kev pabcuam yog nqa tawm hauv SDH lub nplhaib sib txuas.
OTN network feem ntau yog lub nplhaib sib txuas, mesh network thiab lwm tus koom tes sib tham, uas tuaj yeem muab kab 1 + 1 tiv thaiv, yoj yoj 1 + 1 tiv thaiv, cov qhua tuaj sab 1 + 1 tiv thaiv, ODUk tiv thaiv, kho qhov muag txheej thiab hluav taws xob txheej tiv thaiv, thiab lwm yam
Lub sijhawm ua lag luam muaj peev xwm:
Nyob rau hauv OTN, kev teeb tsa cov ntaub ntawv tuaj yeem siv rau kev sib txuas tus ntoo cuam, ntau hom kev pab tuaj yeem nkag mus rau tib lub sijhawm, thiab ntse kev teeb tsa cov kev pabcuam tuaj yeem pom.
Daim ntawv thov nar
DWDM siv feem ntau hauv kev sib koom ua ke hauv lub xeev thiab cov pob txha caj qaum hauv lub xeev, feem ntau yog hauv-taw-rau-taw tes hom, uas tuaj yeem paub txog kab kev tiv thaiv. OTN network muab txoj kev daws teeb meem zoo rau cov kev pab cuam loj broadband. Nws xa OTN pab pawg hauv kev sib txuas lus hauv tuam tsev hauv lub xeev, cov pab pawg hauv tuam txhab hauv nroog, thiab cov tub ntxhais ua haujlwm hauv kev sib tham hauv cov lag luam, thiab muab cov sijhawm ua haujlwm ntawm cov kev pabcuam sab saud GB / s.
