Dab tsi yog qhov sib txawv ntawm PM lim WDM thiab Tff WDM?
Wavelength division multiplexing (WDM) thev naus laus zis yog qhov muaj peev xwm hloov kho kho qhov muag ntawm kev sib txuas lus sib txawv ntawm WDM thiab PM (Polarization tswj hwm) lim WDM yog ob yam Kev siv {.} Muaj qhov sib txawv hauv lawv cov cai ua haujlwm, cov yam ntxwv thiab kev siv cov xwm txheej.
{{01. Ua haujlwm ua haujlwm ntawm cov qauv thiab cov qauv tsim qauv
PM lim WDM
Tsis zoo li Sff WDM, PM lim WDM pab pawg ua haujlwm tshwj xeeb hauv lub hom phiaj ntawm lub hom phiaj tshwj xeeb, xws li lub xeev tshwj xeeb kom paub tseeb tias kev kho kho kho qhov muag tseem ceeb unchanged thaum kis .
Txheej txheem, PM lim WDM kuj muaj cov khoom siv lim, tab sis them nyiaj ntau dua, txhawm rau kom muaj cov txheej txheem ntawm kev sib kis no Tus qauv tsim thiab tsim cov txheej txheem .
Tuff Wdm
Cov tub ntxhais ntawm Tff Wdm ntaus ntawv yog cov yeeb yaj kiab nyias nyias muaj kev siv hluav taws xob tsis muaj txiaj ntsig los ntawm kev npaj ua kom txawv thiab rov siv dua tshiab wavelengths .
Cov khoom siv wdm feem ntau yog tsim ntawm ntau qhov kev sib koom ua ke thiab kev sib xyaw ua ke ntawm cov chaw sib xyaw ua ke thiab cov kev sib xyaw ua ke yog cov khoom sib xyaw ua ke kev sib txuas, thiab cov khoom lag luam broadband .

PM lim WDM
PM lim WDM cov cuab yeej siv tau siv hauv kev sib txuas lus kho qhov muag thiab muaj kev sib txuas lus ntawm cov txheej txheem sib txawv ntawm cov khoom siv kho kho kho kho qhov muag tau ua rau lawv lub sijhawm sib txawv ntawm cov neeg ua haujlwm sib txawv thiab demicInterxing, Li no txhim kho kev ua haujlwm, ruaj khov, thiab kev ntseeg tau .
Ib qho ntxiv, PM lim WDM cov cuab yeej siv tau muaj siab thiab cov khoom siv polarization uas muaj kev sib txuas lus sib txawv ntawm cov tshuab sib txawv thiab kho qhov muag pom kev sib txuas lus zoo nkauj ... {2 2}}
Tuff Wdm
Vim nws cov qauv yooj yim, tus nqi qis thiab kev sib koom ua ke ntawm cov khoom sib txuas lus sib txawv ntawm cov hluav taws xob sib xyaw ua ke ntawm cov hluav taws xob sib txuas lus ntau yam tsis nce tus nqi ntawm fiber ntau tso .
Ib qho ntxiv, TFFM cov cuab yeej muaj muaj kev ntseeg siab thiab ruaj khov} Qhov no tuaj yeem ua rau muaj kev sib txuas lus kho tshiab thiab qhov tseem ceeb hauv thaj chaw sib txuas lus.
tag
Hauv cov ntsiab lus, TFFM thiab PM lim WDM yog ob qho kev sib cais WDM uas muaj kev sib txawv ntawm kev ua haujlwm ntawm lub ntsej muag ua haujlwm, tsim nyog rau kev sib xyaw ua ke ntawm kev ua haujlwm polarization, haum rau polarization-rhiab Cov Kev Siv . Qhov kev xaiv ntawm lawv nyob ntawm kev xav tau thiab muaj peev xwm txhim kho hauv cov ntaub ntawv siv thev naus laus zis, txuas ntxiv mus rau cov ntaub ntawv niaj hnub no.
