32 ports CATV WDM EDFA
EDFA, lossis Erbium-doped Fiber Amplifier, siv Erbium-doped fiber ntau ua qhov nruab nrab kho qhov muag kom ncaj qha txhim kho cov teeb liab. Qhov nruab nrab amplifying yog iav optical fiber doped nrog erbium ions. Lub erbium-doped fiber ntau nce nruab nrab amplifies lub teeb ntawm wavelengths uas yog nyob rau hauv lub zej zog ntawm 1550 nm-qhov optical wavelengths uas raug kev txom nyem yam tsawg kawg nkaus attenuation nyob rau hauv optical fibers.
Wavelength Division Multiplexing (WDM: Wavelength Division Multiplexing) yog ib qho cuab yeej siv ib txhij xa ntau lub wavelength signals nyob rau hauv ib qho optical fiber. WDM thev naus laus zis ua rau muaj peev xwm kis tau tus mob ntawm fiber ntau optical ob peb zaug mus rau kaum tawm lub sij hawm lossis txawm ntau pua zaus piv nrog ib lub wavelength kis tau tus mob, yog li ua kom muaj peev xwm kis tau tus mob fiber ntau, txo cov nqi, thiab muaj txiaj ntsig zoo ntawm daim ntawv thov thiab kev lag luam.
PON + EDFA daim ntawv thov EDFA optical amplifier tsuas yog siv rau 1550nm, uas ua rau CATV hla fiber ntau tranmission ntau dua. PON ua haujlwm nrog EDFA los ntawm FWDM, uas paub txog triple FTTH daim ntawv thov.
