I te nuinga o te wā, ka taea te whakarōpū i ngā taputapu ONU kia rite ki ngā horopaki tono rerekē, pēnei i te SFU, te HGU, te SBU, te MDU, me te MTU.
1. Te whakatinanatanga o te SFU ONU
Ko te painga o tēnei aratau whakatinanatanga ko te nui o ngā rauemi whatunga, ā, he pai mō ngā whare motuhake i roto i ngā horopaki FTTH. Ka taea e ia te whakarite kia whai mana te kiritaki ki te mahi urunga whānui, engari kāore e uru ki ngā mahi uaua o te kuwaha kāinga. I roto i tēnei taiao, e rua ngā aratau noa o te SFU: ko ngā atanga Ethernet me ngā atanga POTS. Ko ngā atanga Ethernet anake e whakaratohia ana. Me mōhio kei roto i ngā āhua e rua, ka taea e te SFU te whakarato i ngā mahi taura coaxial hei whakahaere i te whakatinanatanga o ngā ratonga CATV, ā, ka taea hoki te whakamahi me te kuwaha kāinga hei whakahaere i te whakarato ratonga tāpiri uara. Ka pā anō hoki tēnei āhuatanga ki ngā umanga kāore e hiahia ki te whakawhiti raraunga TDM.
2. Te whakatinanatanga o te HGU ONU
He rite te rautaki whakatinanatanga o te pūrua HGU ONU ki te SFU, engari ko ngā mahi ONU me te RG kua whakauruhia ki roto i ngā taputapu. Ki te whakatauritea ki te SFU, ka taea e ia te whakatinana i ngā mahi whakahaere me te whakahaere uaua ake. I roto i tēnei horopaki whakatinanatanga, ka hangaia ngā atanga āhua-U ki roto i ngā taputapu ā-tinana, ā, kāore e whakarato i ngā atanga. Mena e hiahiatia ana ngā taputapu xDSLRG, ka taea te hono tika i ngā momo atanga maha ki te whatunga kāinga, he rite ki te kuwaha kāinga me ngā atanga hononga EPON, ā, e pā ana ki ngā tono FTTH.
3. Te whakatinanatanga o te SBU ONU
He pai ake tēnei otinga whakatinanatanga mō ngā kaiwhakamahi hinonga motuhake ki te hanga whatunga i roto i te aratau tono FTTO, ā, e hangai ana ki ngā huringa hinonga i roto i ngā horopaki whakatinanatanga SFU me HGU. I roto i tēnei taiao whakatinanatanga, ka tautoko te whatunga i te mahi a te pūwhakauru whānui, ā, ka whakaratohia ki ngā kaiwhakamahi ngā atanga raraunga maha, tae atu ki ngā atanga El, ngā atanga Ethernet, me ngā atanga POTS, e tutuki ai ngā whakaritenga hinonga mō te whakawhitiwhiti raraunga, te whakawhitiwhiti reo, me ngā raina motuhake TDM. Ka taea e te atanga āhua-U i roto i te taiao te whakarato ki ngā hinonga he maha ngā āhuatanga o te hanganga anga, he kaha ake.
4. Te whakatinanatanga o te MDU ONU
Ka pā te otinga whakatinanatanga ki te hanganga whatunga maha-kaiwhakamahi i roto i ngā momo FTTC, FTTN, FTTCab, me te FTTZ. Mena kāore he whakaritenga a ngā kaiwhakamahi hinonga mō ngā ratonga TDM, ka taea hoki te whakamahi i tēnei otinga ki te whakatinana i ngā whatunga EPON. Ka taea e tēnei otinga whakatinanatanga te whakarato ratonga whakawhitiwhiti raraunga whānui mō ngā kaiwhakamahi maha, tae atu ki ngā ratonga Ethernet/IP, ngā ratonga VoIP, me ngā ratonga CATV, ā, he kaha hoki ngā āheinga tuku raraunga. Ka taea e ia tauranga whakawhitiwhiti te hono atu ki tētahi kaiwhakamahi whatunga, nō reira he nui ake te whakamahinga o tana whatunga.
5. Te whakatinanatanga o te MTU ONU
Ko te otinga whakatinanatanga MDU he panonitanga arumoni e hangai ana ki te otinga whakatinanatanga MDU. Ka whakaratohia e ia he maha ngā ratonga atanga, tae atu ki ngā atanga Ethernet me ngā atanga POTS, ki ngā kaiwhakamahi hinonga maha, e tutuki ana i ngā whakaritenga ratonga maha pērā i te reo, te raraunga, me ngā raina motuhake TDM. Ina honoa ki te hanganga whakatinanatanga mokamoka, ka taea te whakatutuki i ngā mahi pakihi whai rawa me te kaha ake.
