Tuatahi, ko te OLT he pūrua raina whatu, ā, ko te ONU he waeine whatunga whatu (ONU). He taputapu hononga whatunga tuku whatu ēnei e rua. Ko ngā kōwae e rua e tika ana i roto i te PON: PON (Whatunga Whatu Āhua: Whatunga Whatu Āhua Āhua). Ko te tikanga o te PON (whatunga whatu āhua) kāore he taputapu hiko me ngā pūtake hiko hiko i roto i te (whatunga tohatoha whatu). Ko te ODN he mea tito katoa mai i ngā taputapu āhua pērā i ngā wehewehe whatu (Splitter) ā, kāore e hiahiatia he taputapu hiko hohe utu nui. Kei roto i te whatunga whatu āhua he pūrua raina whatu (OLT) kua tāutahia ki te teihana whakahaere matua, me te puranga o ngā waeine whatunga whatu taurite taumata tuatahi (ONU) kua tāutahia ki te pae kaiwhakamahi. Kei roto i te whatunga tohatoha whatu (ODN) i waenganui i te OLT me te ONU ngā muka whatu me ngā wehewehe whatu āhua āhua, ngā hononga rānei.
Ko te Pouara (Pouara) he taputapu e hono ana ki ngā whatunga rohe me ngā whatunga whānui o te Ipurangi. Ka tīpako aunoa, ka whakatakoto huarahi kia rite ki ngā āhuatanga o te hongere, ā, ka tukuna ngā tohu ki te ara pai rawa atu, kia tika hoki te raupapa. Ko te pouara te pokapū o te Ipurangi, ko te "pirihimana waka." I tēnei wā, kua whānuitia te whakamahinga o ngā pouara i ngā āhuatanga katoa o te ao, ā, kua noho ngā hua o ngā momo rerekē hei kaha matua ki te whakatinana i ngā hononga ā-roto whatunga tuara, ngā hononga whatunga tuara, me ngā ratonga hononga whatunga tuara me te Ipurangi. Ko te rerekētanga matua i waenga i te pouara me ngā pana ko ngā pana kei te paparanga tuarua o te tauira tohutoro OSI (paparanga hononga raraunga), ko te pouara kei te paparanga tuatoru, te paparanga whatunga. Mā tēnei rerekētanga ka whakatauhia me whakamahi te pouara me te pana i ngā mōhiohio whakahaere rerekē i roto i te tukanga neke mōhiohio, nō reira he rerekē ngā huarahi e rua ki te whakatutuki i ā rāua mahi.
Ko te Pouara (Router), e mōhiotia ana ko te taputapu kuwaha (Gateway), e whakamahia ana hei hono i ngā whatunga maha kua wehea ā-arorau. Ko te mea e kiia nei ko te whatunga arorau e tohu ana i tētahi whatunga kotahi, i tētahi whatunga iti rānei. Ina tukuna ngā raraunga mai i tētahi whatunga iti ki tētahi atu, ka taea te mahi mā te mahi ara o te pouara. Nō reira, ko te mahi a te pouara he aromatawai i te wāhitau whatunga me te whiriwhiri i te ara IP. Ka taea e ia te whakatū hononga ngāwari i roto i tētahi taiao hononga maha-whatunga. Ka taea e ia te hono i ngā whatunga iti maha me ngā mōkihi raraunga me ngā tikanga urunga pāpāho rerekē. Ka whakaaetia e te pouara te teihana pūtake, te mōhiohio rānei o ētahi atu pouara he momo taputapu honohono i te paparanga whatunga.
