Ftth Mini Node
Ftth mini txog ntawm
SR2020AW, qhov haujlwm ua haujlwm ntawm 47 ~ 1000MHz, yog lub zog qis, kev ua haujlwm siab, kev siv nyiaj ntawm kev ua si peb npaug, FTTH CATV lub qhov muag txais, tuaj yeem siv hauv analog TV lossis digital TV.
Cov khoom uas muaj rhiab siab kho qhov muag txais lub raj xa hluav taws xob thiab lub suab qis tshwj xeeb hluav taws xob ua ke. Tau txais ntawm lub zog loj kho qhov muag tuaj yeem hloov kho los ntawm PAD qib, ua si txwv kev tsim tawm, yog li no ftth mini node nyob rau hauv ntau qhov loj ntawm qhov tau txais ntawm lub zog tau txais ntawm optical2 dBm ~ -21dBm, muaj cov yam ntxwv zoo.
