OTN kis tau tus mob thev naus laus zis yog ib qho kev siv tshuab uas paub txog kev ua haujlwm xws li kev pabcuam teeb liab kis tau tus mob, multiplexing, thiab routing hauv qhov chaw kho qhov muag. Cov thev naus laus zis no ua raws li cov qauv dav dav ntawm kev sib kis network tau teev tseg hauv ITU-T6.805. Los ntawm qhov kev xav ntawm OTN network muaj pes tsawg leeg, nws tuaj yeem muab faib ua cov txheej txheem kho qhov muag, txheej txheej txheej txheej, txheej txheej txheej txheej kho qhov muag thiab cov txheej txheem kho qhov muag sib txuas. OTN network feem ntau suav nrog cov thev naus laus zis tseem ceeb xws li kho qhov muag buffering thev naus laus zis, wavelength conversion technology thiab optical timeing regeneration technology. OTN network tuaj yeem suav tau tias yog kev hloov pauv ntawm txhua qhov kev kho qhov muag network, uas ua rau muaj txiaj ntsig zoo rau cov ntaub ntawv xa tawm ntawm lub network uas twb muaj lawm.
Lub network ciaj sia taus mechanism ntawm optical txheej thiab hluav taws xob txheej ntawmOTN kis tau tus mobthev naus laus zis kuj tseem ua tiav, uas tuaj yeem ua kom ntseeg tau qhov kev sib kis ntawm cov teeb liab, thiab muaj peev xwm kho qhov yuam kev thiab kev tswj hwm hierarchical. Kev tswj hwm thiab saib xyuas cov txheej txheem ntawm txhua txheej ntawm lub network yog qhov zoo tshaj plaws, thiab kev ua haujlwm ntawm kev xa tawm, kev tiv thaiv thiab kev saib xyuas tuaj yeem ua tiav hauv WDM system. Cov txheej txheem kho qhov muag hauv OTN network tuaj yeem hloov kho lub sijhawm teeb tsa kho qhov muag hauv kev pabcuam tus neeg nqa khoom, thiab muab ntau hom kev tiv thaiv raws li cov kev pabcuam ntawm cov txheej txheem kho qhov muag thiab cov txheej txheem hluav taws xob, muab ntau yam kev tiv thaiv rau cov kev pabcuam tseem ceeb, thiab ua tau raws li qhov yuav tsum tau ua kom ruaj khov. kev ua haujlwm network. OTN thev naus laus zis tau siv dav hauv cov pob txha kis tau tus mob thiab lub nroog loj hauv cheeb tsam sib txuas. Nws tuaj yeem ua kom muaj peev xwm sib kis tau zoo hauv lub network, txo kev siv cov kev tsim kho network, thiab ua tau raws li cov kev xav tau ntawm kev loj hlob sai ntawm cov kev pabcuam mobile network.
Raws li cov khoom ntawm kev sib koom ua ke ntawm daim phiaj hluav taws xob thiab tag nrho-optical network,OTN kis tau tus mobthev naus laus zis muaj txiaj ntsig zoo heev rau kev siv. OTN thev naus laus zis tuaj yeem txhawb nqa daim duab qhia ntawm ntau tus neeg siv khoom, xws li SDH (synchronous digital signal transmission), ATM (asynchronous transmission) thiab Ethernet. Hauv OTN Hauv thev naus laus zis, bandwidth particle ntawm cov txheej txheem hluav taws xob yog cov ntaub ntawv ntawm txoj kev kho qhov muag, thiab lub wavelength yog siv los ua bandwidth particle ntawm optical txheej, kom cov khoom rau multiplexing thiab hla yog qhov loj, thiab Kev sib kis tau zoo tuaj yeem txhim kho ntxiv.
OTN muaj peev xwm saib xyuas thiab tswj tau zoo. Ntxiv rau kev muab kev tswj hwm nyiaj siv ua haujlwm zoo ib yam li SDH, nws tseem tuaj yeem muab cov haujlwm xws li TCM (tandem saib xyuas), kom OTN tuaj yeem saib xyuas lub network los ntawm qhov kawg-rau-kawg thiab ntau pawg sib txuas thaum sib txuas. kev ua tau zoo. OTN thev naus laus zis qhia txog qhov kho qhov muag ntxiv-poob multiplexer nrog cov haujlwm kho dua tshiab, uas txhim kho nws txoj kev sib txuas tau zoo heev. OTN txais yuav kev sib xyaw ntawm cov txheej txheem kho qhov muag thiab kev tiv thaiv kev sib txuas kho qhov muag kom zoo tiv thaiv lub network, thiab qhov sib ntxiv ntawm kev kho tus kheej lub nplhaib network thev naus laus zis ua rau OTN ua kom tiav tsis siv neeg rov qab thaum tsis ua haujlwm.
