ONU yog qhov peb feem ntau hu ua "lub teeb miv", ONU lub teeb qis yog hais txog qhov tshwm sim uas lub hwj chim kho qhov muag tau txais los ntawm ONU tsawg dua qhov tau txais kev nkag siab ntawm ONU.Qhov tau txais rhiab heev ntawm ONU hais txog qhov tsawg kawg nkaus kho qhov muag lub zog uas ONU tuaj yeem tau txais thaum lub sijhawm ua haujlwm ib txwm muaj.Feem ntau, qhov tau txais rhiab heev Performance index ntawm lub tsev broadband ONU yog -27dBm;Yog li ntawd, ONU tau txais lub zog kho qhov muag qis dua -27dBm feem ntau txhais tau tias yog ONU lub teeb tsis muaj zog.
ONU yog qhov peb feem ntau hu ua "lub teeb miv", ONU lub teeb qis yog hais txog qhov tshwm sim uas lub hwj chim kho qhov muag tau txais los ntawm ONU tsawg dua qhov tau txais kev nkag siab ntawm ONU.Qhov tau txais rhiab heev ntawm ONU hais txog qhov tsawg kawg nkaus kho qhov muag lub zog uas ONU tuaj yeem tau txais thaum lub sijhawm ua haujlwm ib txwm muaj.Feem ntau, qhov tau txais rhiab heev Performance index ntawm lub tsev broadband ONU yog -27dBm;Yog li ntawd, ONU tau txais lub zog kho qhov muag qis dua -27dBm feem ntau txhais tau tias yog ONU lub teeb tsis muaj zog.
Muaj ntau yam uas cuam tshuam rau tus neeg siv kev paub hauv online.ONU lub teeb qis feem ntau cuam tshuam rau lub network ceev.Txhawm rau ntsuas qhov cuam tshuam ntawm ONU lub teeb tsis muaj zog ntawm tus neeg siv lub network ceev, Laodingtou tau tsim cov qauv ntsuas hauv qab no.
Txuas lub ntsuas hluav taws xob kho qhov muag thiab PON kho qhov muag hluav taws xob ntsuas hauv cov kab ntawm cov tawv cable thiab ONU, kom lub PON kho qhov muag fais fab ntsuas tuaj yeem siv los ntsuas qhov tau txais lub zog kho qhov muag ntawm ONU (qhov qis qis hluav taws xob kho qhov muag ntawm qhov ntsuas).Qhov sib txawv ntawm qhov tau txais lub zog kho qhov muag ntawm ONU yog hais txog 0.3dB (1 fiber ntau jumper rho tawm qhov txo qis ntawm kev sib txuas ua haujlwm).Qhov chaw sim tiag tiag yog li no.
Los ntawm kev kho qhov attenuation ntawm adjustable attenuator, lub attenuation ntawm ODN txuas tuaj yeem nce ntxiv, thiab qhov tau txais lub zog kho qhov muag ntawm ONU tuaj yeem hloov pauv.Kev hloov pauv ntawm kev sib txuas ceev yog sim los ntawm kev txuas lub laptop rau ONU nrog lub network cable.Txoj kev no yog siv los ntsuas 300M broadband ntawm Laodingtoujia, thiab cov txiaj ntsig kev xeem yog raws li hauv qab no.
Qhov tseeb tau txais rhiab heev ntawm feem ntau ONUs yog zoo dua qhov Performance index ntawm li 1.0dB.Piv txwv li, ONUs hauv qhov kev sim no tseem tuaj yeem ua haujlwm ib txwm muaj thaum txais lub zog kho qhov muag siab dua -27.98dBm.Thaum lub hwj chim kho qhov muag tau txais qis dua -27.98dBm, lub downlink network ceev poob sai nrog qhov txo qis ntawm qhov tau txais lub hwj chim kho qhov muag, thiab tuav lub network qis heev nyob rau hauv ib qho chaw kho qhov muag kom txog thaum lub network cuam tshuam tag nrho.
