Fiber Optic Sensor Ua haku ʻia ka mea ʻike fiber optic me kahi kumu kukui, kahi fiber hanana, kahi pulupulu puka, kahi modulator māmā, kahi ʻike kukui, a me kahi demodulator. ʻO ke kumu kumu, ʻo ia ka hoʻouna ʻana i ke kukui o ke kumu kukui i ka wahi modulation ma o ka fiber hanana, a hui pū ke kukui ...

ʻO ka hoʻokele pūnaewele ka hōʻoia o ka hilinaʻi o ka pūnaewele a me ke ala e hoʻomaikaʻi ai i ka pono o ka pūnaewele. ʻO ka hana, ka hoʻokele a me ka mālama ʻana i nā hana o ka hoʻokele pūnaewele hiki ke hoʻonui nui i ka manawa i loaʻa o ka pūnaewele, a hoʻomaikaʻi i ka helu hoʻohana, ka hana pūnaewele, ka lawelawe ...

1 Hoʻomaka Me ka hoʻomohala wikiwiki ʻana o ka ʻenehana hiki i ka broadband, ua puka mai nā ʻano ʻenehana ʻike ākea ākea ma hope o ka ua. Ma hope o ka ʻenehana PON ʻo ka ʻenehana DSL a me ka ʻenehana kelepona, kahi paepae kūpono ʻē aʻe, hiki iā PON ke hāʻawi pololei i nā lawelawe optical a i ʻole FTTH s ...

1 Introduction Ua kapa ʻia ʻo PoE ʻo Power over LAN (PoL) a i ʻole Active Ethernet, i kekahi manawa i kapa ʻia ʻo Power over Ethernet no ka pōkole. ʻO kēia ka hōʻailona maʻamau hou loa e hoʻohana ana i nā kaula hoʻouna Ethernet maʻamau e hoʻouna i ka ʻikepili a me ka mana i ka manawa like, a mālama i ka compatib ...

ʻO ka manaʻo nui o ka Power Over Electricity (POE) POE (Power Over Ethernet) e pili ana i kekahi mau kikowaena IP-based (e like me nā kelepona IP, nā wahi komo LAN uea ʻole AP, nā pahu kiʻi pūnaewele, a me nā mea ʻē aʻe) me ka hoʻololi ʻole i ka ʻōnaehana uila Ethernet Cat.5. ʻOiai e hoʻouna ana i nā hōʻailona ʻikepili, hāʻawi ia i ka mana DC ...

ʻO PON (Passive Optical Network) ʻo ia hoʻi, ʻaʻohe mea hana a hoʻohana wale i ka Optical Fiber and Passive Components ma waena o OLT ( Optical Line Terminal) a me ka ONU ( Optical Network Unit). A ʻo PON i ka ʻenehana nui e hoʻokō i ka FTTB / FTTH, ka mea nui e hoʻohana i ka point to multi-point network ...
