Taw qhia:ONU(Optical Network Unit) muab faib ua active optical network units thiab passive optical network units.ONUyog ib tug neeg siv khoom siv nyob rau hauv optical networks, muab tso rau ntawm tus neeg siv kawg, thiab siv ua ke nrogOLTkom ua tiav Ethernet Layer 2 thiab Layer 3 ua haujlwm, muab cov neeg siv lub suab, cov ntaub ntawv, thiab cov kev pabcuam multimedia.
Kev piav qhia ntawmONUvaj huam sib luag ntsuas:
POWER teeb: ntsuab tawm: fais fab tuag: fais fab tuag
PON lub teeb: Ntsuab rau: Ntev ntev qhia tias lub rooj tsavxwm tau dhau qhov kev kuaj tus kheej thiab lub cuab yeej ua haujlwm ib txwm
LOS teeb: tsis nyob rau: lub xeev qub
Txheeb xyuas cov neeg siv tsis raug:
Cov faults feem ntau yog optical path faults thiabONUntaus ntawv yuam kev. Ua ntej, xyuas seb lub teeb qhia vaj huam sib luag puas yog qhov qub. Txheeb xyuas PON teeb pom kev zoo rau qhov teeb meem kho qhov muag: PON teeb ib txwm teeb ntsuab, qhia tias txoj kev kho qhov muag zoo li qub, thiab PON teeb tawm, qhia tias txoj kev kho qhov muag puas lawm.
Siv lub ntsuas hluav taws xob kho qhov muag los ntsuas txoj kev kho qhov muag. Qhov siv tau ntawm lub zog kho qhov muag yog: 1490nm: - 8db txog - 28db. Yog tias qhov ntau dhau lawm, nws yuav cuam tshuam rau kev ua haujlwm zoo ntawm covONU, thiab tus neeg siv kev siv internet yuav raug cuam tshuam. Kos rau sab sauv txoj kev kho qhov muag, thiab mus rau lub thawv kho qhov muag cable txhawm rau kuaj tus Tsov tus tw fiber ntau ntawm cov splitter sib xws rau cov neeg siv khoom siv kho qhov muag tsis raug.
Attenuation ntawm 1: 2 channel splitter yog - 3 db
1: 4 channel splitter attenuation yog - 6db
Lub attenuation ntawm 1: 8 channel splitter yog - 9db,
1:16 channel splitter attenuation yog - 12db,
Lub attenuation ntawm 1:32 channel splitter yog - 15 db,
Lub attenuation ntawm 1:64 channel splitter yog - 18db,
1, Yog hais tias cov zis optical zog ntawm lub splitter pigtail yog tsim nyog, thov hloov lub fiber core ntawm lub optical cable hlws ris box thiab lub tsev. Feem ntau, peb yuav nteg tsawg kawg yog ob lub cores fiber ntau rau lub tsev, thiab tom qab ntawd ua qhov kev xeem kawg tom qab hloov. Yog tias lub zog kho qhov muag ntawm lub pigtail los ntawm lub splitter tsis tsim nyog, thov hloov cov pigtail ntxiv, thiab siv lub ntsuas hluav taws xob kho qhov muag los ntsuas qhov tsim nyog los txuas rau lub tsev pigtail.
Yog hais tias nws yog ib qho kev ua txhaum txoj kev kho qhov muag: Ua ntej, unplug lub pigtail ntawm lubONUmus kuaj lub hwj chim kho qhov muag. Yog tias tsis muaj lub teeb lossis lub zog tsis tsim nyog, thov nrhiav ib qho ntawm 1-32 pigtails sib haum rauONUnyob rau ntawm lub flange ntawm lub optical cable hlws ris lub thawv, thiab unplug lub pigtail los ntawm lub flange mus kuaj lub optical zog. Yog tias pigtail tsis tsim nyog, hloov ib qho ntawm 1-32 idle pigtails. Nco ntsoov tias lub ntsiab fiber ntau ntawm lub splitter tsis tuaj yeem raug tshem tawm, uas yuav cuam tshuam rau txhua tusONUs.

Tom qab lub cuab yeej ua haujlwm ib txwm, nrhiav lwm yam laj thawj. Cov txheej txheem yog tib yam li tau piav qhia saum toj no.
