ONU (Wāhanga Whatunga Whatu) Wāhanga whatunga whatu, ka wehea te ONU ki te wāhanga whatunga whatu hohe me te wāhanga whatunga whatu kore. Ko te tikanga, ko ngā taputapu e mau ana i ngā kaiwhiwhi whatu, ngā tuku whatu hononga-ake, me ngā whakakaha piriti maha mō te aroturuki whatunga ka kiia he pūnga whatu. Ka whakamahia e te PON he muka whatu kotahi hei hono atu ki te OLT, kātahi ka honoa te OLT ki te ONU. Ka whakaratohia e te ONU ngā ratonga pēnei i te raraunga, te IPTV (Pouaka Whakaata Ipurangi Tauwhitiwhiti), te reo (mā te whakamahi i te IAD, Pūrere Uru Whakauru), ā, ka tino whakatinanahia ngā tono "takaro-toru".
I te nuinga, ka taea te whakarōpū i ngā taputapu ONU kia rite ki ngā horopaki tono rerekē pēnei i te SFU, HGU, SBU, MDU, me te MTU.
1. Te whakatinanatanga momo SFU ONU
Ko te painga o tēnei tikanga whakatinanatanga ko te nui o ngā rauemi whatunga, ā, he pai mō ngā whare motuhake i roto i te horopaki FTTH. Ka taea e ia te whakarite kia whai mahi urunga whānui te pito kaiwhakamahi, engari kāore e uru ki ngā mahi uaua o te kuwaha kāinga. E rua ngā momo noa o te SFU i roto i tēnei taiao: te whakarato i ngā tauranga Ethernet me ngā tauranga POTS; me te whakarato i ngā tauranga Ethernet anake. Me mōhio ka taea e te SFU i roto i ngā momo e rua te whakarato i ngā mahi taura coaxial hei whakahaere i te whakatinanatanga o ngā ratonga CATV, ā, ka taea hoki te whakamahi me ngā kuwaha kāinga hei whakahaere i te whakarato ratonga tāpiri uara. Ka pā hoki tēnei āhuatanga ki ngā umanga kāore e hiahia ki te whakawhiti raraunga TDM.
2. Te whakatinanatanga momo HGU ONU
He rite te rautaki whakatinanatanga o te momo HGU ONU terminal ki te momo SFU, engari ko ngā mahi a te 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, kua hangaia te atanga āhua-U ki roto i te taputapu ā-tinana, ā, kāore e whakarato i tētahi 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 tētahi kuwaha kāinga me tētahi atanga hononga-ake EPON. Ka whakamahia ki ngā wā FTTH.
3. Te whakatinanatanga momo SBU ONU
He pai ake tēnei otinga whakatinanatanga mō te hanganga whatunga o ngā kaiwhakamahi hinonga motuhake i roto i te aratau tono FTTO, ā, he huringa hinonga tēnei i runga i ngā horopaki whakatinanatanga SFU me HGU. Ka taea e te whatunga i raro i tēnei taiao whakatinanatanga te tautoko i te mahi a te taunga urunga whānui me te whakarato ki ngā kaiwhakamahi he maha ngā atanga raraunga tae atu ki te atanga El, te atanga Ethernet, me te atanga POTS, ka taea te whakatutuki i ngā hiahia o ngā hinonga i roto i te whakawhitiwhiti raraunga, te whakawhitiwhiti reo, me ngā ratonga raina tūmataiti TDM. Ngā whakaritenga whakamahinga. Ka taea e te atanga āhua-U i roto i te taiao te whakarato ki ngā hinonga he hanganga anga me ngā āhuatanga rerekē, ā, he kaha te mahi.
4. Te whakatinanatanga o te momo MDU ONU
He pai tēnei otinga whakatinanatanga mō te hanganga whatunga i raro i ngā momo tono maha-kaiwhakamahi pērā i te FTTC maha-kaiwhakamahi, FTTN, FTTCab, me te FTTZ. Mena kāore e hiahiatia ana e ngā kaiwhakamahi taumata-hinonga ngā ratonga TDM, ka taea hoki te whakamahi i tēnei otinga mō te whakatinanatanga whatunga EPON. Ka taea e tēnei kaupapa whakatinanatanga te whakarato ki ngā kaiwhakamahi maha-ngā ratonga whakawhitiwhiti raraunga whānui tae atu ki ngā ratonga Ethernet/IP, ngā ratonga VoIP, me ngā ratonga CATV me ētahi atu momo ratonga maha-ratonga, ā, he kaha hoki ngā āheinga tuku raraunga. Ka taea e ia o ōna tauranga whakawhitiwhiti te hono atu ki tētahi kaiwhakamahi whatunga, nō reira, ki te whakatauritea, he teitei ake te tere whakamahi whatunga.
5. Te whakatinanatanga o te momo MTU ONU
He panonitanga arumoni tēnei otinga whakatinanatanga e ahu mai ana i te otinga whakatinanatanga MDU. Ka taea e ia te whakarato i ngā ratonga atanga maha-hinonga ki ngā kaiwhakamahi maha-hinonga tae atu ki ngā atanga Ethernet me ngā atanga POTS, ā, ka taea hoki te whakatutuki i ngā ratonga maha pērā i te reo, te raraunga, me ngā ratonga raina riihi TDM o ngā hinonga. Mena ka whakamahia ngātahitia te hanganga whakatinanatanga momo-mokamoka, ka taea te whakatutuki i ngā mahi pakihi whai rawa ake, whai mana ake hoki.
