Los ntawm kev sib piv lub phiaj xwm passive thiab cov kev ua haujlwm ib nrab, peb paub tias ob qhov qauv muaj tib yam khoom ntawm lub hauv paus nres tsheb sab: passive wavelength faib + xim lub teeb xim. Qhov txawv tseem ceeb yog kev teeb tsa ntawm ib sab ntawm chav sib sau ua ke.
Vim li no, los koom ua ke cov khoom lag luam saum toj saud, muaj ob txoj hauv kev siv los hloov zuj zus los ntawm cov phiaj xwm ntshiab dhau mus rau cov haujlwm ib nrab:
Thawj:Hauv lub xeev ntawm qhov kev daws teeb meem, qhov faib ua ntu ntev ntawm lub ntsej muag sib faib + kho qhov muag ntawm cov khoom sib hloov ntawm chav sab tau maj mam hloov mus rau qhov chaw nres tsheb sab, thiab cov khoom siv ntawm cov khoom sib txuas rau chav sab tau hloov nrog cov sib xyaw sib kis platform { {1}} wavelength faib board + xim lub teeb module + OTU Cov kev pab cuam board + kev kho qhov muag module + kho qhov muag pab pawg tuaj yeem paub cov kev hloov pauv los ntawm kev daws teeb meem mus rau semi-nquag tov, thiab yuav tsis ua rau cov pov tseg ntawm cov khoom lag luam muaj kev yuav khoom dhau los ntawm kev daws teeb meem dhau los.
Thib Ob:Hauv kev daws teeb meem dhau los, qhov ntsuas phoo WDM nyob rau sab ntawm qhov sib dhos ua ke tau ua rau hauv daim npav hom WDM uas tau sib xyaw rau cov chaw sib kis. Tom qab ntawd, thaum koj xav tau hloov zuj zus los ntawm qhov kev daws teeb meem mus rau qhov kev daws teeb meem ib nrab, koj tsuas yog xav tau ntxiv" kev sib kis sib kis platform + xim lub teeb module + OTU qhov kev pab cuam board + kev pab cuam kho qhov muag kho qhov muag + pawg tiv thaiv kho qhov muag" nyob rau ntawm ib sab ntawm chav sib hloov ua ke kom ua tiav qhov tsis tuaj yeem hloov pauv.
Qhov saum toj no ob hom kev kawm yog los ntawm cov ntshiab passive schemes rau kev siv thaum ntxov ntawm peb tes num, thiab tom qab ntawd hloov kho mus rau hauv cov phiaj xwm ib nrab. Txoj kev daws teeb meem muaj qhov pom tseeb, kev tsim kho yooj yim, cov khoom lag luam rov qab, tsis muaj khib nyiab, cov cuab yeej siv qis dua thiab cov nqi zog. Ntxiv mus, qhov kev hais daws teeb meem ib nrab yog ntse heev thiab tuaj yeem paub txog kev tswj lub network tej thaj chaw deb, uas nws yooj yim rau kev saib xyuas kev ua haujlwm thiab kev tu xyuas cov neeg ua haujlwm.
Lub zog dhau ntawm WDM kev daws teeb meem muaj kev tsim kho qis thiab tuaj yeem daws cov teeb meem ntawm cov khoom siv fiber ntau nplua nuj. Txoj kev daws teeb meem no yog tsim los ntawm cov cuab yeej siv kho qhov muag kom zoo thiab muaj tus lej poob qis dua li WDM kev daws teeb meem. Kev daws teeb meem ib nrab ntawm WDM muab kev ua haujlwm zoo thiab kev saib xyuas lub zog ntawm sab kev ua si thaum daws cov teeb meem ntawm cov khoom siv nplua nuj kho qhov muag, thiab tseem tsis tuaj yeem zam qhov kev tswj hwm ntawm cov teeb ci xim ntawm cov chaw nres tsheb.
