FTTH Fiber Broadband Troubleshooting Guide rau cov neeg siv hauv tsev

Yog tias koj muaj FTTH fiber ntau hauv tsev, tej zaum koj yuav muaj kev cuam tshuam los sis qeeb qeeb. Cov teeb meem feem ntau yog me me thiab tsis xav tau kev sib cuag nrog koj ISP tam sim ntawd. Cov lus qhia ua tiav no suav nrog ONT (Optical Network Terminal) cov lus qhia daws teeb meem- yooj yim txaus rau cov pib tshiab los kho cov teeb meem sai. Bookmark nws rau yav tom ntej siv!

Feem ntau cov teeb meem ONT hauv tsev poob rau hauv peb pawg:teeb liab, kev sib txuas, thiab kev teeb tsa. Kev kho vajtse loj heev tsis tshua muaj. Pib nrog kev kuaj xyuas ua ntej hu rau koj tus kws kho mob kom ua tau zoo dua.

I. Kos qhov taw qhia teeb: Nrhiav qhov yuam kev hauv 30 vib nas this (zoo tshaj rau cov pib tshiab)

ONT lub teeb ua haujlwm ua lub teeb ua - hauv kev ua yuam kev. Nco peb lub teeb tseem ceeb no txhawm rau txheeb xyuas cov teeb meem sai sai.

(Cov tuam txhab yuav siv cov ntawv sib txawv me ntsis, tab sis kev ua haujlwm zoo ib yam.)

Lub teeb muaj zog (POWER)

Tawm: Xyuas lub hwj chim adapter, cable, thiab lub hwj chim qhov hluav taws xob; sim ib lub qhov (socket) sib txawv.

Khoom siv: Fais fab mov yog qhov qub.

Fiber Signal Teeb (LOS / OPTICAL)

Liab (khoom los yog flashing): Fiber teeb liab abnormality.

Unplug thiab reinsert lub fiber connector maj mam, ntxuav qhov chaw nres nkoj; yog tias lub teeb liab tseem nyob, tiv tauj koj ISP rau kev daws teeb meem kab.

LAN Chaw nres nkoj teeb (LAN)

Tawm: Tshawb xyuas Ethernet cable txuas, puas, lossis sim lwm qhov chaw nres nkoj LAN / cable.

Flashing: Cov ntaub ntawv kis tau ib txwm - tsis tas yuav ua dab tsi.

II. Kauj ruam-los ntawm-Kev daws teeb meem rau cov teeb meem tshwm sim

Nrog lub teeb raws li kev siv, ua raws cov kauj ruam no los kho 80% ntawm cov teeb meem niaj hnub- tsis tas yuav tsum muaj cov cuab yeej tshaj lij.

Fault 1: Txhua yam khoom siv offline, tsis muaj internet nkag

Txheeb xyuas cov ntsuas: Yog tias LOS / Optical liab, rov ntxig lub fiber ntau txuas.

Rov pib dua: Tshem tawm ob qho tib si ONT thiab router, tos tsawg kawg 30 vib nas this. Qhib ONT ua ntej (tos ~ 2 feeb kom lub teeb kom ruaj khov), ces lub router.

Yog tias tseem offline: Txuas lub computer ncaj qha rau ONT ntawm Ethernet.

Ua haujlwm: Teeb meem yog nrog lub router.

Tsis ua haujlwm: Hu rau ISP txhawm rau txheeb xyuas cov nqi them tsis tau them lossis kho kab.

Fault 2: PPPoE dial-ua tsis tau tiav (bridge hom)

Tsom ntsoov rau qhov chaw thiab cov ntsiab lus ntawm tus account:

Paub meej tias router WAN tau teeb tsaPPPoE dial -up, nrog rau qhov tseeb broadband username thiab password (case-sensitive, tsis muaj chaw ntxiv).

Pib dua ONT thiab router, tom qab ntawd rov hu dua -up.

Yog tseem ua tsis tau:

Dial up manually los ntawm lub computer txuas ncaj qha rau ONT.

Ua tsis tiav: Hu rau ISP kom unbind account lossis rov pib tus password.

Ua tiav: Rov teeb tsa lub router dial -up settings.

Fault 3: qeeb qeeb heev (deb hauv qab cov phiaj xwm sau npe)

ONT teeb tsa thiab xwm txheej ncaj qha cuam tshuam rau kev ceev:

Kuaj ceev nrog lub computertxuas ncaj qha rau ONT. Yog tias qeeb, xyuas lub zog kho qhov muag (ib txwm muaj: -10 ~ -28 dBm); hu rau ISP yog tias txawv txav.

Xyuas kom ONT LAN chaw nres nkoj yoggigabit (GE / 1000M)thiab cable yog Cat5e lossis siab dua (Cat6 pom zoo rau 300M + broadband).

Hloov mus rau hom choj yog siv hom router; lov tes taw ONT's built-hauv Wi‑Fi kom txo tau kev cuam tshuam thiab tso tawm bandwidth.

Fault 4: nquag reboots & overheating

Feem ntau hais txog ib puag ncig thiab kev siv hluav taws xob:

Muab ONT tso rau hauv qhov chaw qhib, qhov cua kom deb ntawm qhov chaw sov kom tsis txhob muaj cua sov.

Siv covthawj, sib phim fais fab adapterkom tsis txhob muaj lub zog tsis ruaj khov.

Yog tias reboots txuas ntxiv: Hu rau ISP los hloov ONT (zoo li kho vajtse tsis ua haujlwm).

III. Beginner yuam kev kom zam

Tsis txhob nias lub Reset khawm casually: Nws tshem tawm tag nrho cov kev teeb tsa thiab xav tau ISP rov- rau npe.

Tsis txhob yuam-plug fiber connectors: Kov maj mam; ntxuav cov chaw nres nkoj nrog cov ntaub so ntswg huv xwb.

TSIS TXHOB hloov kho qhov chaw siab tshaj: Optical power, firmware, protocols, etc., yuav tsum tau hloov kho los ntawm ISP cov kws tshaj lij.

IV. Cov ntsiab lus

Feem ntau hauv tsev ONT teeb meem yog me. Nco ntsoov peb cov kauj ruam tseem ceeb:

Tshawb xyuas qhov taw qhia teeb ua ntej.

Ua kom rov pib dua.

Tshawb xyuas kev sib txuas thiab kev teeb tsa.

Feem ntau cov teeb meem tuaj yeem daws tau yam tsis muaj kev hu mus rau koj ISP.

Txuag phau ntawv qhia no kom ceev ceev thaum twg koj ONT ua!
