Judge neeg siv fault:
Feem ntau ntawm qhov txhaum yog qhov ua txhaum ntawm cov kab hluav taws xob fiber ntau thiab ONU cov khoom tsis raug.Ua ntej, xyuas seb qhov ntsuas vaj huam sib luag puas zoo li qub.Nyob rau hauv cov ntaub ntawv ntawm optical fiber kab tsis ua hauj lwm, saib cov xwm txheej ntawm PON lub teeb: yog hais tias lub PON lub teeb ntsuab, nws qhia tau hais tias lub optical fiber kab yog ib txwm, thiab yog hais tias lub PON lub teeb tawm, nws qhia tau hais tias lub optical fiber kab yog disconnected.
Ntsuas cov kab hluav taws xob kho qhov muag nrog lub ntsuas hluav taws xob kho qhov muag.Qhov tsim nyog ntau ntawm optical zog yog: 1490nm ntau: - 8dB txog - 28dB.Yog tias nws tshaj qhov ntau, nws yuav cuam tshuam rau kev ua haujlwm zoo ntawm ONU thiab tus neeg siv kev siv Internet yuav raug cuam tshuam.Txheeb xyuas cov kab hluav taws xob sab saud thiab ntsuas tus Tsov tus tw fiber ntau ntawm lub splitter sib haum rau cov neeg siv khoom siv kho qhov muag cable ntawm lub thawv kho qhov muag.
Lub attenuation ntawm 2-txoj kev kho qhov muag splitter yog -3db
Lub attenuation ntawm 4-txoj kev kho qhov muag splitter yog -6db
Lub attenuation ntawm 8-txoj kev kho qhov muag splitter yog -9db
Lub attenuation ntawm 16-txoj kev kho qhov muag splitter yog -12db
Lub attenuation ntawm 32-txoj kev kho qhov muag splitter yog -15db
Lub attenuation ntawm 64-txoj kev kho qhov muag splitter yog -18db
1.Yog tias cov zis hluav taws xob kho qhov muag ntawm lub splitter pigtail tsim nyog, thov hloov cov tub ntxhais fiber ntau ntawm lub thawv hloov kho qhov muag thiab lub tsev.Feem ntau, peb nteg tsawg kawg yog ob lub fiber ntau hauv lub tsev, thiab tom qab ntawd sim thaum kawg tom qab hloov.Yog hais tias nws yog tus Tsov tus tw los ntawm lub splitter thiab nws optical zog ntawm lub fiber yog tsis tsim nyog, thov hloov lub spare pigtail, thiab siv ib tug kho qhov muag lub hwj chim meter mus kuaj ib tug tsim nyog mus cuag lub tsev pigtail.
2.Yog tias cov kab hluav taws xob kho qhov muag tsis raug: thawj zaug tshem tawm cov pigtail ntawm ONU los kuaj lub zog kho qhov muag, yog tias tsis muaj lub teeb lossis lub zog tsis tsim nyog, thov mus rau lub flange ntawm lub thawv hloov kho qhov muag kom pom ib qho ntawm 1-32 pigtails ntawm optical splitter sib haum rau ONU Yog tias cov pigtail tsis tsim nyog, koj tuaj yeem hloov ib qho ntawm 1-32 idle pigtails.Nco ntsoov: lub ntsiab fiber ntau ntawm optical splitter tsis tuaj yeem rub tawm, uas yuav cuam tshuam tag nrho ONU.
ONU Vaj Huam Sib Luag qhov taw qhia piav qhia:
Lub hwj chim: lub teeb ntsuab ib txwm nyob: Fais fab rau;Green light off: Fais fab tuag
LOS Lub Teeb: OFF: Lub zog kho qhov muag tau txais ntawm PON chaw nres nkoj yog qhov qub;Lub teeb ntsuab ib txwm nyob rau: Cov cuab yeej tau tshawb pom thiab sau npe;Lub teeb ntsuab ntsais: Lub cuab yeej tsis muaj ntaub ntawv;Blink: PON chaw nres nkoj tsis muaj lub teeb lossis lub zog kho qhov muag qis dua qhov tau txais rhiab heev.
LAN1, LAN2, LAN3 thiab LAN4 yog tag nrho 4RJ45 Chaw nres nkoj
FXS1 yog Voice Port
Kev daws teeb meem: Ua ntej, xyuas seb lub cuab yeej ONU puas ua haujlwm zoo li qub (txawm tias lub teeb taw qhia ntawm lub vaj huam sib luag yog qhov qub), thiab tom qab ntawd xyuas lwm yam laj thawj tom qab lub cuab yeej ua haujlwm ib txwm.Cov txheej txheem yog tib yam li cov saum toj no.
Yog xav paub ntxiv ONU / lub thawv ONU / kev sib txuas lus ONU / optical fiber ONU, koj tuaj yeem tiv tauj ncaj qha rau HDV Phoelectron Technology LTD kom paub meej ntxiv.Peb lub tuam txhab kuj muaj cov khoom sib txuas lus ntawm OLT, Media Converter, Hloov thiab SFP.Txais tos kom sab laj.
