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 ...

Me ka hoʻomohala ʻana o nā ʻupena kamaʻilio e pili ana i ka broadband a me ka neʻe ʻana, ua hoʻohui ʻia ka optical fiber wireless communication system (ROF) i ke kamaʻilio fiber optical a me ke kamaʻilio uila, e hāʻawi ana i ka pāʻani piha i nā pono o ka broadband a me ka anti-interference o nā laina fiber optical, e like me ...

ʻO ka hoʻololi PoE kahi hoʻololi e kākoʻo ana i ka lako mana i ke kaula pūnaewele. Ke hoʻohālikelike ʻia me ka hoʻololi maʻamau, ʻaʻole pono e hoʻopaʻa ʻia ka mana e loaʻa ai ka mana (e like me AP, kikohoʻe kikohoʻe, a me nā mea ʻē aʻe) no ka lako mana, a ʻoi aku ka kiʻekiʻe o ka hilinaʻi o ka pūnaewele holoʻokoʻa. Ka nānā 'ana o Power Over Et...
