ʻO ka mea loaʻa ʻo FTTH Optical (CT-2002C)
Nānā nui
ʻO kēia huahana he FTTH optical receiver, me ka hoʻohana ʻana i ka ʻenehana optical haʻahaʻa haʻahaʻa a me ka mana optical ʻenehana AGC, hiki ke hoʻokō i nā pono o ka fiber-to-the-home, a hiki ke hoʻohana pū ʻia me ONU a i ʻole EOC e hoʻokō i ka pāʻani triple.Aia ka WDM, 1550nm CATV hōʻailona photoelectric hoʻololi a me ka RF puka, 1490/1310 nm PON hōʻailona hele pololei ma, hiki ke hālāwai me FTTH hoʻokahi optical fiber transmission CATV + XPON.
Paʻa ka huahana a maʻalahi hoʻi e hoʻokomo, a he huahana kūpono ia no ke kūkulu ʻana i kahi ʻupena TV FTTH.

FAQ
FTTH Optical Receiver Nīnau pinepine
Q1.He aha ka mea hoʻokipa optical FTTH?
A: He mea hoʻohana ʻia ka FTTH optical receiver ma nā pūnaewele fiber-to-the-home (FTTH).Hoʻolālā ʻia e loaʻa i nā hōʻailona optical mai nā pūnaewele fiber optic a hoʻololi iā lākou i mau hōʻailona uila no ka hana hou ʻana.
Q2.Pehea e hana ai ka FTTH optical receiver?
A: Hoʻohana ka FTTH optical receiver i ka hoʻokipa optical haʻahaʻa haʻahaʻa a me ka ʻenehana optical automatic gain control (AGC).Hoʻomaopopo ka ʻenehana AGC i ka loaʻa ʻana o ka mana optical i loko o kahi kikoʻī kikoʻī ma o ka hoʻoponopono ʻana i ka loaʻa o ka mea hoʻokipa.Mālama kēia i ka hoʻokipa hōʻailona hilinaʻi a me ka hana maikaʻi loa.
Q3.He aha nā pōmaikaʻi o ka hoʻohana ʻana i ka FTTH optical receiver?
A: ʻO ka hoʻohana ʻana i nā mea hoʻokipa optical FTTH e lawe mai i nā pono he nui i nā pūnaewele FTTH.Hiki iā ia ke hoʻokipa maikaʻi i ka hōʻailona fiber optic a me ka hoʻololi ʻana, hiki i ka Internet wikiwiki kiʻekiʻe, TV kikohoʻe kiʻekiʻe kiʻekiʻe, a me nā lawelawe leo akaka.Eia hou, hiki ke hoʻohui ʻia me kahi Optical Network Unit (ONU) a i ʻole Ethernet ma luna o Coax (EOC) no nā lawelawe pāʻani ʻekolu.
Q4.He aha nā mea hoʻohana o FTTH optical receivers?
A: Hoʻohana nui ʻia nā mea hoʻokipa optical FTTH i nā pūnaewele FTTH e hoʻopili i nā hale noho a i ʻole nā ʻoihana pāʻoihana me nā ʻōnaehana fiber optic.He mea hana ia e lawe ai i nā hōʻailona optical e hele ana ma o nā uwea fiber optic a hoʻohuli iā lākou i nā hōʻailona uila kūpono no nā lawelawe like ʻole, e like me ka Internet, televise, a me ka leo.
Q5.Hiki ke hoʻohana ʻia ka FTTH optical receiver me nā mea hana ʻē aʻe?
A: ʻAe, hiki ke hoʻohana pū ʻia ka FTTH optical receiver me ONU a i ʻole EOC e ʻike i ka lawelawe pāʻani ʻekolu.Hana ʻo ONU ma ke ʻano he kikowaena kikowaena no ka hoʻolaha ʻana i nā hōʻailona pūnaewele, TV a me nā leo i loko o ka hale, ʻoiai ʻo ka FTTH optical receivers e hōʻoiaʻiʻo i ka hoʻokipa a me ka hoʻololi ʻana i kēia mau hōʻailona.Ke kākoʻo pū nei lākou i ka pilina pili ʻole a me nā lawelawe multimedia ma nā pūnaewele FTTH.
