I kēia ao, ʻoi aku ka nui o ka loaʻa ʻana o kahi pilina pūnaewele hilinaʻi ma mua. ʻO ia kahi i komo ai kēia 1550nm CATV Mini Fiber Optic Transmitter - i hoʻolālā ʻia no nā pūnaewele FTTH (Fiber To The Home), hāʻawi ia i ka linearity maikaʻi loa a me ka palahalaha e hōʻoia i nā pilina paʻa a me ka wikiwiki. Hoʻomaopopo mākou i ke koʻikoʻi o nā ʻāpana kiʻekiʻe, ʻo ia ke kumu e hoʻohana ai kā mākou huahana i nā mea hoʻoikaika ikaika o GaAs amplifier no ka hoʻomaikaʻi ʻana i ka hana. ʻO ka pohō kiʻekiʻe o ka fiber mode-hoʻokahi e hōʻoiaʻiʻo iā ʻoe e loaʻa i ka hapa nui o kāu lawelawe pūnaewele. Ma waho aʻe o ka hana kupanaha, hoʻohana kā mākou huahana i ka ʻenehana noise ultra-low no nā pilina hilinaʻi mau.
ʻO DFB coaxial liʻiliʻi pūʻolo lasers e hōʻoia i ka ikaika a paʻa kāu mau pilina. ʻAʻole maikaʻi wale kā mākou huahana, akā ua hoʻolālā pū ʻia me ka maʻalahi o ka hoʻokomo ʻana. He liʻiliʻi ka nui a me kahi kaʻina hoʻonohonoho maʻalahi. ʻO ka hōʻailona mana LED ʻulaʻula e ʻike mau ʻoe i kona kūlana. ʻO ka hoʻokomo kālā ʻana i kā mākou huahana, ʻo ia ka hoʻopukapuka kālā i ka wā e hiki mai ana o ka pilina pūnaewele o kou home. E kōkua mākou iā ʻoe e pili pū me ka lawelawe wikiwiki a hilinaʻi. E ʻoluʻolu e kipa i kā mākou pūnaewele no ka ʻike hou aku, nā nīnau, e ʻoluʻolu e kelepona iā mākou.
