Hauv lub network fiber-optic broadband (FTTH), ONU (optical network unit) yog cov cuab yeej tseem ceeb ntawm tus neeg siv kawg, lub luag haujlwm hloov kho qhov muag teeb liab rau hauv cov teeb liab hluav taws xob, ua rau cov tsev lossis cov lag luam nkag mus rau hauv Internet. Txawm li cas los xij, hauv kev siv tiag tiag, ONU yuav ntsib teeb meem xws li lub zog kho qhov muag tsis tshua muaj zog thiab tsis muaj peev xwm sau npe, ua rau muaj kev cuam tshuam hauv network lossis txo qis network ceev. Kab lus no yuav qhia txog yuav ua li cas daws teeb meem sai sai thiab daws cov teeb meem no, thiab muab cov txheej txheem ua haujlwm uas txawm tias tsis yog cov kws tshaj lij tuaj yeem pib tau yooj yim.

Ⅰ.Tsawg ONU optical zog: ua rau thiab kev daws teeb meem
1. Lub hwj chim kho qhov muag yog dab tsi?
Lub hwj chim kho qhov muag hais txog qhov kev siv ntawm lub teeb liab optical tau txais los ntawm ONU, hauv dBm (decibel milliwatts).
Qhov ntau yam yog feem ntau:
-8 dBm rau -27 dBm (GPON / EPON)
-Txog -28 dBm tuaj yeem ua rau lub network tsis ruaj khov lossis cuam tshuam
- Saum toj no -8 yuav ua rau ONU rov pib dua thiab tso npe tsis ruaj khov
2.Yuav ua li cas kuaj xyuas lub hwj chim kho qhov muag?
Cov npe sib txawv ntawm ONUs muaj ntau txoj hauv kev los kuaj xyuas, tab sis lawv tuaj yeem raug kuaj xyuas raws li hauv qab no:
① Web tswj interface (xws li 192.168.1.1, nkag mus rau tus thawj tswj account password) → Status → Optical module cov ntaub ntawv
② ONU qhov taw qhia: Yog tias LOS (tsis muaj teeb liab kho qhov muag) lub teeb liab, nws txhais tau hais tias lub hwj chim kho qhov muag tsawg dhau los yog cov khoom siv kho qhov muag raug txiav.
③ Siv lub ntsuas hluav taws xob kho qhov muag (feem ntau siv los ntawm kev ua haujlwm thiab kev saib xyuas cov neeg ua haujlwm)
3.Feem ntau ua rau thiab cov kev daws teeb meem rau lub hwj chim kho qhov muag qis
| Ua rauOf Failure | Kev daws teeb meemMethod | Kev daws |
| Fiber yog khoov los yog puas | Tshawb xyuas seb cov fiber ntau puas yog khoov (tshwj xeeb tshaj yog ntawm qhov sib koom ua ke) | Ncaj cov fiber ntau kom tsis txhob 90 ° khoov |
| Dirty Fiber Connector | Xyuas seb SC/APC/UPC connector puas plua plav | Ntxuav Nrog Cawv Cawv Paj Rwb los yog Plua plav-dawb ntaub |
| Qhov kho qhov muag attenuation loj dhau (dhau ntawm OLT) | Ntsuas seb qhov hluav taws xob kho qhov muag qis dua -28dBm | Hu rau tus neeg teb xov tooj kom kho lub splitter lossis ua kom luv luv |
| Splitter Failure | Puas yog lwm tus neeg siv ntawm tib PON chaw nres nkoj ib txwm | Tus neeg teb xov tooj hloov lub optical splitter |
| ONU Optical Module Kev laus | Hloov lwm ONU rau Kev Xeem | Hloov ONU tshiab |
Nco tseg:
1. Tsis txhob saib ncaj qha ntawm lub ntsej muag fiber ntau, lub laser yuav ua rau koj ob lub qhov muag!
2. Yog tias koj tsis tuaj yeem daws qhov teeb meem ntawm koj tus kheej, nws raug nquahu kom hu rau tus neeg teb xov tooj rau kev kho, nws yuav muaj teeb meem nrog lub cev kho qhov muag cable.
Ⅱ. ONU kev sau npe tsis ua haujlwm: ua rau thiab kev daws teeb meem
1. Kev sau npe ONU yog dab tsi?
ONU yuav tsum tau sau npe nrog tus neeg teb xov tooj OLT (optical kab davhlau ya nyob twg) kom nkag mus rau Is Taws Nem ib txwm. Yog tias kev sau npe tsis ua tiav, cov teeb meem xws li flashing liab network teeb thiab dial-up tsis ua haujlwm (PPPoE yuam kev) yuav tshwm sim.
2. Yuav ua li cas txiav txim siab tsis ua hauj lwm rau npe?
① PON teeb tawm / flashing (feem ntau nws yuav tsum qhib)
②Cov kev tswj xyuas interface qhia "tsis tau sau npe" lossis "kev lees paub ua tsis tiav"
③Thaum hu xovtooj mus nkag rau hauv Is Taws Nem, nws hais tias "678/651 yuam kev" (tej zaum yuav txawv hauv cheeb tsam sib txawv)
3.Cov laj thawj thiab kev daws teeb meem rau kev sau npe tsis ua haujlwm
| Ua rauOf The Problem | Kev daws teeb meemMethod | Kev daws |
| LOID/SN Code yuam kev | Tshawb xyuas seb LOID (broadband identification code) puas raug nkag | Rov nkag mus rau LOID (muab los ntawm tus neeg teb xov tooj) |
| OLT version yog incompatible | Xyuas seb ONU Model Txhawb Cov Neeg Ua Haujlwm Network | Hloov tus neeg teb xov tooj-certified ONU |
| Optical hwj chim tsawg dhau | Tshawb xyuas lub zog kho qhov muag raws li thawj ntu | Kho qhov teeb meem optical fais fab tuag thiab sau npe dua |
| Tus neeg teb xov tooj khi MAC | Sim clone tus thawj ONU MAC chaw nyob | Hu rau tus neeg teb xov tooj kom tshem tawm lossis hloov lub cuab yeej |
| Cov peev txheej PON tsis txaus | Ntau tus neeg siv ntau dhau ntawm tib PON chaw nres nkoj | Tus neeg teb xov tooj kho PON chaw nres nkoj teeb tsa |
Kev ua haujlwm piv txwv (coj CeitaTech ONU ua piv txwv):
1. Nkag mus rau kev tswj hwm interface (192.168.100.1) → nkag mus rau LOID (muab los ntawm tus neeg teb xov tooj).
2. Nyem "Sau npe" thiab tos kom lub teeb PON nyob rau los qhia txog kev ua tiav.
3. Yog tias nws ua tsis tiav, sim "Restart ONU" lossis "Restore Factory Settings" thiab rov sau npe dua.
Ⅲ. Kev kuaj ceev ntawm lwm yam teeb meem tshwm sim
1. ONU tuaj yeem sau npe tab sis nkag tsis tau hauv Is Taws Nem?
① Txheeb xyuas seb tus PPPoE tus lej password puas raug (muab los ntawm tus neeg teb xov tooj).
② Sim hloov lub network cable lossis router rau kev sim.
2. ONU nquag disconnect?
① Nws yuav yog tus nqi tseem ceeb ntawm lub zog kho qhov muag (txog -27dBm), thiab qhov kev sib txuas ntawm fiber ntau yuav tsum tau ua kom zoo.
② Tshawb xyuas cov cua kub dissipation ntawm ONU kom tsis txhob muaj kev ruaj ntseg los ntawm qhov kub thiab txias.
3. Yuav ua li cas los txiav txim seb nws yog ONU teeb meem lossis teeb meem tus neeg teb xov tooj?
① Puas yog lwm tus neeg siv nyob rau hauv tib lub PON chaw nres nkoj ib txwm? Yog tias lawv tag nrho txawv txav, nws yuav yog OLT tsis ua haujlwm.
② Ntsuas nrog lub ntsuas hluav taws xob kho qhov muag. Yog tias lub hwj chim kho qhov muag zoo li qub tab sis tsis tuaj yeem sau npe, nws yuav yog ONU tsis ua haujlwm.
IV. Summary: ONU kev daws teeb meem
1. Tshawb xyuas lub hwj chim kho qhov muag ua ntej (txawm nws nyob nruab nrab ntawm -8dBm thiab -28dBm).
2. Tshawb xyuas cov khoom siv kho qhov muag thiab cov khoom sib txuas (txawm nws yog khoov lossis qias neeg).
3. Paub meej tias LOID/SN code yog lawm (hu rau tus neeg teb xov tooj kom tau txais nws).
4. Rov pib ONU lossis rov sau npe tom qab rov qab kho lub Hoobkas teeb tsa.
5. Tseem daws tsis tau nws? Hu rau tus neeg teb xov tooj kom ceeb toom nws (nws yuav muaj teeb meem nrog OLT lossis lub cev kho qhov muag cable).
Raws li cov txheej txheem no, feem ntau ONU qhov ua txhaum tuaj yeem nyob sai thiab daws tau! Yog tias koj ONU tseem muaj teeb meem, txais tos hu rau peb! WhatsApp / Xov tooj: +86 13714107074
