ʻO ka OLT kahi laina laina opitika, ʻo ONU kahi ʻāpana pūnaewele optical (ONU), ʻo lākou nā mea hoʻopili pūnaewele hoʻoili optical āpau.ʻElua mau modula pono i PON: PON (Passive Optical Network: passive optical network).ʻO ka PON (passive optical network) e pili ana i (optical distribution network) ʻaʻole i loaʻa nā mea uila a me nā lako uila uila, ua haku ʻia ʻo ODN i nā mea passive e like me ka optical splitter (Splitter), ʻaʻole koi i nā lako uila hana pipiʻi.Aia i loko o ke kikowaena opitika passive kahi kikowaena laina opitika (OLT) i ho'okomo 'ia ma ke kikowaena mana o ke kikowaena, a me ka pū'ulu o ke kāko'o 'ana o nā pūnaewele 'opika (ONUs) i ho'okomo 'ia ma ka pūnaewele mea ho'ohana.Aia i loko o ka pūnaewele hoʻolaha ʻike (ODN) ma waena o ka OLT a me ka ONU nā fiber optical a me nā mea hoʻokaʻawale passive a i ʻole nā mea hoʻohui.
ʻO nā alahele a me nā hoʻololi nā mea hoʻololi ʻikepili.
ODN (Optical Distribution Network) he FTTH optical cable network ma muli o ka lako PON.ʻO kāna kuleana ka hāʻawi ʻana i kahi kaila hoʻouna optical ma waena o ka OLT a me ka ONU.Mai ka hiʻohiʻona hana, hiki ke hoʻokaʻawale ʻia ʻo ODN i ʻehā mau ʻāpana: ʻo ka subsystem cable optical feeder, ka subsystem optic cable subsystem, ka subsystem cable optical cable subsystem a me ka subsystem terminal fiber optical mai ka hopena o ke keʻena a hiki i ka hopena mea hoʻohana.
ʻO ONT kahi ʻāpana koʻikoʻi o ONU.
ʻO FTTB "pilikia i ka hale", 16 mau ONU i hoʻokomo ʻia i loko o ka pahu hui ma ke alahele.He 16 ONT ma ka ONU.Hoʻopuka kēlā me kēia ONT i kahi uwea pūnaewele (hōʻailona uila) a hiki i kēlā me kēia mea hoʻohana ma o ke kaula pūnaewele ma ke alahele.
FTTH "fiber-to-the-home", kau i ka 1 a 16 splitter i loko o ka pahu hui ma ke alahele, a laila hiki i kēlā me kēia mea hoʻohana ma o ka uhi uhi i loko o ke alahele, a hoʻopau kēlā me kēia mea hoʻohana i kahi ONT.Ua like ia me ka wehe ʻana i ka ONU, no laila ua kokoke loa ka mea hoʻohana i ka mea hoʻohana.
Hiki ke hoʻomaopopo ʻia ʻo ONT he ONU me hoʻokahi awa.
