I te ao tūhonohono o ēnei rā, he mea nui te hanganga whatunga pono, whai hua hoki mō ngā umanga me ngā kaiwhakahaere. Ko te pana POE tētahi o ngā wāhanga nui e whai wāhi nui ana ki te hononga whatunga. Ka whakamahia e ngā pana PoE ngā hangarau matatau, ā, ka whai i ngā paerewa ahumahi hei whakarato i ngā kaiwhakahaere ki te EPON OLT momo pouaka kaha-waenga kua whakauruhia, he mea tino pai mō ngā whatunga urunga me ngā whatunga puni umanga. I roto i tēnei tuhinga, ka tūhuratia e mātou me pēhea te whakanui ake i te whai huatanga o te whatunga e ngā pana POE, ā rātou whakaritenga hangarau, me ngā painga e kawea mai ana e rātou ki ngā pakihi.
Te whakamāramatanga me te mahi a te pana POE:
Pana POEKo te whakarāpopototanga tēnei o te pana Power over Ethernet, he taputapu e whakakotahi ana i ngā mahi tuku raraunga me te tuku hiko ki te kotahi waeine. He mea hanga ēnei hei EPON OLT momo pouaka-whakauru-teitei, kaha-waenga, e tutuki ana i ngā paerewa hangarau IEEE802.3 ah me te tutuki i ngā whakaritenga taputapu YD/T 1945-2006 EPON OLT. Ka tukuna e ēnei pana he māmā me te whai hua mā te whakakore i te hiahia mō tētahi taura hiko motuhake, ka whakapiki ake i te pai me te whakaiti i ngā utu.
Ngā whakaritenga hangarau me te tuwhera:
Ko te whanaketanga o ngā pana POE e aro nui ana ki ngā whakaritenga hangarau. E whai ana rātou i te paerewa Whatunga Whatu Āhua Ethernet Passive (EPON), e whakarite ana i te whakaurunga pai ki ngā pūnaha whatunga o nāianei. Hei tāpiri, kua hangaia kia tutuki ai ngā whakaritenga hangarau EPON 3.0 i whakatakotoria e China Telecom. E whai ana ngā pana POE i ēnei paerewa, he pai te tuwhera, ā, ka taea te whakauru me te hototahi ki ngā momo taputapu whatunga.
Te kaha nui, te pono nui:
Ko tētahi āhuatanga nui o ngā pana POE ko tōna kaha nui, e whakanui ana i te tauine i te tipu haere o te whatunga. Ka taea e ngā pakihi te whakawhānui i ā rātou hanganga whatunga me te kore e manukanuka ki te iti o te kaha. Hei tāpiri, he tino pono ngā pana POE hei whakarite i te hononga kore e mutu mō ngā tono nui, me te whakaiti i te wā kore mahi. He mea nui tēnei pumau mō ngā pakihi e whakawhirinaki nui ana ki te hononga whatunga mō ngā mahi o ia rā.
He tino mahi ngā mahi a te pūmanawa, ā, he nui hoki te whakamahinga o te whānui o te hononga:
He whānui ngā mahi pūmanawa kei roto i ngā pana POE, e āhei ai ngā kaiwhakahaere ki te whakahaere me te arotau i ā rātou whatunga. Mā ngā āhuatanga pēnei i te tautoko VLAN, te kounga o te ratonga (QoS), me te whakahaere waka ka taea e ngā umanga te whakarite i ngā tono nui me te whakarite kia whakamahia pai te whānui o te roangaru. Mā tēnei āhuatanga ka whakaratohia he mana whakahaere me te ngāwari ki runga i te waka whatunga, ka whakarei ake i te mahi whānui o te whatunga.
Ngā painga mō te pakihi:
Te whakauruNgā pana POEHe maha ngā painga ka puta mai i te whakaurunga ki roto i te hanganga whatunga ki ngā pakihi. Tuatahi, ka whakaitihia e te tukanga tāutanga māmā te uaua me ngā utu e pā ana ki ngā taura hiko motuhake. Tuarua, ko te kaha ake o te tauine me te pono o ngā pana POE ka ārai i te whatunga i te heke mai me te urutau pai ki te tipu. Hei tāpiri, ka whakarite ngā āhuatanga pūmanawa i te whakamahinga pai o te whānui, te whakanui ake i te hua me te whakarato i te wheako kaiwhakamahi maeneene. Hei whakamutunga, mā te whakamahi i ngā pana POE ka taea e ngā umanga te noho rite ki ngā paerewa ahumahi, ka māmā ake te whakauru atu ki ētahi atu pūnaha me ngā taputapu.
hei whakamutunga:
Nā te whakaurunga o ngā pana POE ki roto i te hanganga whatunga kua nui ngā painga ki ngā kaiwhakahaere me ngā umanga. He whānuitanga o ngā āhuatanga e tukuna ana e ēnei pana pēnei i te kaha nui, te pono teitei, te mahi pūmanawa katoa me te whakamahinga pai o te whānui, te whakanui ake i te pai o te whatunga me te whakangawari i te tukanga tāutanga me te piri ki ngā paerewa ahumahi. Mā te haumi ki ngā pana POE, ka taea e ngā pakihi te waihanga i tētahi taiao whatunga pakari me te tauine e tautoko ana i tō rātou tipu me te whakarite i te hononga kore e mutu i roto i te taiao matihiko tere haere o ēnei rā.
