OADM thiab OXC ua haujlwm ntawm DWDM system
OADM tuaj yeem muab cov teeb liab nce thiab nqis ntawm wavelengths ntawm txhua qhov chaw kho qhov muag raws li qhov xav tau (tam sim no 8 wavelengths tuaj yeem ua tiav), qhov haujlwm no koom tes nrog OXC, thiab qee qhov teeb liab kho qhov muag los ntawm ib qho chaw nres nkoj ntxiv tuaj yeem ntxiv rau txhua qhov wavelength ntawm lub cev. , yog li ntawd txawm hais tias lub wavelengths ntawm qhov ntxiv optical signals ntawm ob qhov chaw nres nkoj ntxiv yog tib yam, lawv yuav tsis ua rau muaj kev thaiv. Ib yam li ntawd, ib qho kev poob wavelength kuj tseem tuaj yeem poob rau txhua qhov chaw nres nkoj los ntawm qhov chaw nres nkoj ua haujlwm, uas nthuav dav qhov yooj yim ntawm OADM daim ntawv thov. Tsis tas li ntawd, los ntawm kev sib xyaw ua ke ntawm OADM thiab OXC, ob-fiber one-way multiplex section tiv thaiv, ob-fiber ob-txoj kev multiplex seem tiv thaiv, kev tiv thaiv channel thiab lwm txoj kev tiv thaiv tuaj yeem muab, kom lub nplhaib kho tus kheej. tuaj yeem pom tau, ua rau kev ua haujlwm ruaj ntseg, txhim khu kev qha.
