He aha ka FTTx?
ʻO FTTx ka "Fiber To The x" a ʻo ia ka huaʻōlelo maʻamau no ka loaʻa ʻana o ka fiber i nā kamaʻilio fiber optic. Hōʻike ʻo x i ka wahi e hele ai o ka laina fiber. E like me x = H (Fiber to the Home), x = O (Fiber to the Office), x = B (Fiber to the Building). Loaʻa ka ʻenehana FTTx mai nā lako keʻena kikowaena i loko o ka lumi kelepona ʻāpana a hiki i nā mea hoʻohana i nā mea hoʻohana, me ka laina laina optical (OLT), pūʻulu pūnaewele ʻike (ONU), kikowaena pūnaewele ʻike (ONT).
E like me ka wahi o kaONUma ka hope o ka mea hoʻohana o ka ʻenehana kikowaena optical, he nui nā ʻano FTTx, hiki ke hoʻokaʻawale ʻia i ka fiber i kahoʻololipahu (FTTCab), fiber i ke alanui (FTTC), fiber i ka hale (FTTB), fiber i ka home (FTTH), fiber To the office (FTTO) a me nā ʻano lawelawe ʻē aʻe. ʻO ka mea hoʻohana US ʻo Verizon e pili ana iā FTTB a me FTTH ma ke ʻano he fiber i ka hale (FTTP).
FTTCab（Fiber I ka Aha Kuhina）
Hoʻololi ʻia ke kaula kuʻuna me ka fiber optical. ʻO kaONUwaiho ʻia ma ka pahu hui. ʻO kaONUma lalo e hoʻohana i ka uea keleawe a i ʻole nā mea hoʻolaha ʻē aʻe e hoʻopili ai i ka mea hoʻohana.
FTTC（Fiber To The Curb）
ʻO ka hoʻokomo ʻana a me ka hoʻohana ʻana i nā uwea optical mai ke keʻena kikowaena a i nā alanui i loko o hoʻokahi tausani kapuaʻi o nā hale a i ʻole nā keʻena. ʻO ka maʻamau, waiho mua ʻia kahi loulou hoʻouna broadband kokoke loa i ka mea hoʻohana. I ka manawa e pono ai nā lawelawe broadband, hiki ke alakaʻi koke ʻia ka fiber i ka mea hoʻohana a hiki ke loaʻa ka fiber ma ka home.
FTTB（Fiber i ka Hale)
ʻO ia kahi ala ākea ākea e pili ana i ka ʻenehana pūnaewele fiber optical i hoʻopaʻa ʻia. Hoʻohana ʻo ia i ka fiber i ka hale a me ka uwea pūnaewele i ka home e hoʻokō ai i ke ala ākea ākea o ka mea hoʻohana. ʻO ka maʻamau, hoʻohana ʻia ke komo laina i hoʻolaʻa ʻia, kahi maʻalahi e hoʻouka a hiki ke hāʻawi i ka helu kiʻekiʻe i luna a i lalo o 10Mbps (kūʻokoʻa).
FTTH（Fiber I ka Home）
ʻO ka TTH e pili ana i ka hoʻokomo ʻana i kahi ʻāpana pūnaewele optical (ONU) ma kahi mea hoʻohana home a mea hoʻohana ʻoihana paha. ʻO ia ke ʻano o ka noi pūnaewele ʻike ʻike pili kokoke i ka mea hoʻohana koe wale ʻo FTTD (optic fiber to desktop) i ka moʻo ʻike. Ua lilo ka ʻenehana PON i wahi wela i kaʻana like ʻia e nā mea hoʻohana broadband honua a ua manaʻo ʻia ʻo ia kekahi o nā ʻenehana loea maikaʻi loa e hoʻokō ai i ka FTTH.
FTTP（Fiber i ka hale）
ʻO FTTP kahi huaʻōlelo ʻAmelika ʻĀkau. Loaʻa iā FTTB, FTTC, a me FTTH ma kahi ʻano haiki, a hoʻonui i nā kaula fiber optical i nā hale a i ʻole nā ʻoihana.
