E tautuhia ana e te paerewa ieee802.3av te aratau paparanga ā-tinana kore-taurite 10g/1g (tere hononga-ake 10g/tere hononga-iho 1g) (e kiia nei i konei ko te aratau kore-taurite 10g/1g) me te aratau paparanga ā-tinana kore-taurite e rua (e kiia nei i konei ko te aratau 10g/10g) 10g/10g (he 10g te tere hononga-ake me te tere hononga-iho).
Ka taea e te olt i te aratau kore-tauira 10g/1g te hototahi ki te onu i te aratau ōrite 1g/1g me te onu i te aratau kore ōrite 10g/1g. Ka taea e te OLT i te aratau ōrite 10g/10g te hototahi ki te onu i te aratau 1g/1g, te onu i te aratau kore ōrite 10g/1g, me te onu i te aratau ōrite 10g/10g.
He rite tonu te OLT i te aratau ōrite, me te OLT i te aratau kore ōrite i te ahunga heke o te ara whatu o te paparanga tinana, ā, e whakamahi ana te hongere 10g i te roangaru 1577nm me te waehere 64b/66b; nō reira, ahakoa kei te aratau ōrite, kei te aratau kore ōrite rānei te onu, ka taea e ia te whiwhi raraunga heke mai i te olt. Ka whakapāho te olt i ia wā i te anga mpcpdsicoverygate (tikanga whakahaere maha-ira, kawa whakahaere maha-ira). Ko te āpure mōhiohio kitenga i roto i te anga he mea motuhake hei whakamōhio i te āheinga matapihi hononga-ake (1g, 10g, 1g+10g tere rua), ā, ka taea e te onu te tiki i te olt mā tēnei aratau mahi o nāianei o te anga.
He tino ōrite te onu i te aratau ōrite me te aratau kore ōrite i te paparanga mac (mana urunga pāpāho, paparanga mana urunga waenga), ā, ko te rerekētanga i waenganui i a rāua kei te paparanga phy (paparanga ā-tinana, te paparanga o raro o te osi), ā, ko ngā tawhā tuku o te paparanga phy e whakawhirinaki ana ki te . Whakauruhia te kōwae whatu o te onu:
Ina whakaurua he kōwae whatu kore-taurite ki roto i te onu (arā, he onu kore-taurite te onu), nā te mea ko te tere hononga ake o te kōwae whatu kore-taurite e tae atu ana ki te 1g, ka taea anake e te paparanga phy o te onu te whirihora i te tere tuku o te 1g kia mahi i te aratau kore-taurite. Ina whakaurua he kōwae whatu kore-taurite ki roto i te onu, nā te mea ko te tere hononga ake o te kōwae whatu e tae atu ana ki te 10g, ka taea e te onu te whirihora i te tere tuku o te paparanga phy ki te 10g kia mahi i te aratau kore-taurite, te whirihora rānei i te tere tuku o te paparanga phy ki te 1g kia mahi i te aratau kore-taurite.
Heoi, ka pāngia te onu me te olt e ēnei hapa ina whakahoutia te whatunga:
I te wā whakahou whatunga, ka taea e te OLT te huri i waenga i te aratau ōrite me te aratau kore ōrite, engari kāore e taea e te ONU te huri i runga i te huringa o te OLT. Hei tauira, ka huri te OLT mai i te aratau ōrite ki te aratau kore ōrite, engari kei te aratau ōrite tonu te ONU. I tēnei wā, kāore te aratau pito ā-rohe (olt) me te pito mamao (onu) e ōrite.Ngā āhuatanga whakatinanatanga hangarau:
I runga i te aro ki ngā hapa o mua, ko te raruraru hangarau i whakatauhia e tēnei mahi auaha ko: me pēhea te hanga i te onu kia huri hei aratau hurihanga o te olt ina mahi te olt i te hurihanga o te aratau ōrite/aratau kore ōrite; ka tutuki i tēnei mahi auaha te huinga tino pai o te olt me te urutau onu, kāore he taupatupatu i waenga i te aratau mutunga ā-rohe me te aratau mutunga mamao.
Hei whakatutuki i te kaupapa o runga ake nei, ka urutau te kawenga e whakaratohia ana e tēnei mahi auaha ki te ōritetanga 10g/10g me te kore ōritetanga 10g/1g, tae atu ki ngā mahi e whai ake nei:
Hipanga a: Tikina te momo kōwae whatu o te onu. Mēnā he kōwae whatu ōrite te kōwae whatu, whakatauhia te aratau mahi o nāianei o te onu. Mēnā he aratau ōrite te aratau mahi o te onu, haere ki te taahiraa b; mēnā he aratau kore ōrite te aratau mahi o te onu, haere ki te taahiraa c;
Hipanga b: Whakatauhia mēnā kei runga ake i te paepae kua tohua te maha o ngā mōhiohio matapihi i tukuna e te olt i te aratau kore-taurite, mēnā koinā, whakawhitihia te aratau mahi o te onu mai i te aratau taurite ki te aratau kore-taurite, ka mutu; ki te kore, pupuri i te aratau mahi o te onu, ka mutu;
Hipanga c: Whakatauhia mēnā kei runga ake i te paepae kua tohua te maha o ngā mōhiohio matapihi i tukuna e te olt i te aratau ōrite, mēnā koinā, whakawhitihia te aratau mahi a onu mai i te aratau kore ōrite ki te aratau ōrite, ā, mutu; ki te kore, puritia te aratau mahi a onu, mutu.
I runga i te otinga hangarau i runga ake nei, ko te tukanga mō te tiki i te momo o te kōwae whatu o te onu i whakaahuatia i te taahiraa a koia tēnei: ina tīmata te onu, tikina te momo o te kōwae whatu o te onu:
Mena he kōwae whatu kore-taurite te kōwae whatu, whakamutua te tukanga ka mutu;
Mena he kōwae whatu hangarite te kōwae whatu, ina huri te onu mai i te āhua kore-mārama ki te āhua e tika ana, whakahokia te momo kōwae whatu o te onu, mena he kōwae whatu hangarite te kōwae whatu, haere tonu i te tukanga e whai ake nei o te taahiraa a; mena he kōwae Whatu hangarite kore te kōwae whatu, whakamutua te tukanga ka mutu.
Ko te onu e whakaratohia ana e tēnei mahi auaha ka urutau ki ngā pūnaha ōrite 10g/10g me te 10g/1g kore ōrite, tae atu ki tētahi kōwae kimi onu, tētahi kōwae whakawhiti aratau ōrite, me tētahi kōwae whakawhiti aratau kore ōrite kua whakaritea ki runga i te onu;
Ko te waeine kimi onu e whakamahia ana hei: tiki i te momo waeine whatu o te onu, ina he waeine whatu ōrite te waeine whatu, whakatau i te aratau mahi o nāianei o te onu, mena he aratau ōrite te aratau mahi o te onu, tuku tohu whakawhiti aratau ōrite ki te waeine whakawhiti aratau ōrite; Mena he aratau kore ōrite te aratau mahi o te onu, ka tukuna he tohu whakawhiti aratau kore ōrite ki te waeine whakawhiti aratau kore ōrite;
Ko te wāhanga whakawhiti aratau ōrite te mea e whakamahia ana hei: whai muri i te whiwhinga i te tohu whakawhiti aratau ōrite, te aromatawai mēnā kua tae te maha o ngā mōhiohio matapihi i tukuna e te olt i te aratau kore ōrite ki tētahi paepae kua tohua, ā, mēnā koinā, ka whakawhiti i te aratau mahi o te onu mai i te aratau ōrite ki te aratau kore ōrite; ki te kore, ka pupuri i te aratau mahi o te onu;
Ko te tikanga o te kōwae whakawhiti aratau kore-taurite: i muri i te whiwhinga i te tohu whakawhiti aratau kore-taurite, te aromatawai mēnā kei runga ake i te paepae kua tohua te maha o ngā mōhiohio matapihi i tukuna e te olt ki te aratau taurite, ā, mēnā koinā, ka whakawhiti i te aratau mahi o te onu mai i te aratau kore-taurite ki te aratau taurite; ki te kore, me pupuri tonu te aratau mahi onu.
I runga i te kaupapa hangarau kua whakahuatia ake nei, ko te tukanga mō te tiki i te momo o te kōwae whatu o te onu i roto i te kōwae kimi onu koia tēnei: ina tīmata te onu, tikina te momo o te kōwae whatu o te onu:
Mena he wae whatu kore-taurite te wae whatu, kati te mahi;
Mena he wae whatu ōrite te kōwae whatu, ina huri te onu mai i te āhua kore-mārama ki te āhua e pā ana, whakahokia te momo o te kōwae whatu o te onu. Mena he kōwae whatu ōrite te kōwae whatu, haere tonu te tukanga e whai ake nei o te kōwae kite onu; mena he kōwae whatu kore- ōrite te kōwae whatu, kati te mahi.
Ki te whakatauritea ki ngā mahi toi o mua, ko ngā painga o tēnei mahi hou ko:
(1) E pā ana ki te taahiraa a o tēnei mahi auaha, ka taea te mōhio kua whiwhi tika te mahi auaha i te momo onu; i runga i tēnei kaupapa, e pā ana ki te taahiraa b me te taahiraa c o tēnei mahi auaha, ka kitea ka taea e tēnei mahi auaha te kite i te aratau whakahaere o te olt, ā, e ai ki te aratau whakahaere o te olt, ka taea te urutau ki te whakarite i te aratau mahi o te onu, kia tutuki ai te urutau tino pai i waenga i te olt me te onu, ā, kāore he taupatupatu i waenga i te aratau mutunga ā-rohe me te aratau mutunga mamao i roto i ngā mahi o mua.
(2) E pā ana ki te taahiraa a o tēnei mahi auaha, ka kitea mēnā ka whakatauhia e tēnei mahi auaha he onu kore-taurite te momo onu, arā, ko te onu anake te kaha ki te mahi i roto i te aratau kore-taurite, ā, ka taea anake e te onu te urutau ki te aratau taurite 10g/10g, ā, kāore te tukanga whai muri e mahia i tēnei wā (nā te mea kāore e taea e te onu te huri i ngā aratau mahi), ā, ka whakaitihia ngā utu whakahaere me te whakapai ake i te whai huatanga o te mahi.
(3) E pā ana ki te taahiraa a o tēnei mahi auaha, ka kitea me kite te mahi auaha i te momo o te waeine whatu o te onu ina tīmata te onu, ā, ina huri te onu mai i te āhua pōuri ki te āhua mārama, ā, ka taea e ngā kitenga e rua kua whakahuatia ake nei te kite i te āhua tīmatanga o te onu. Ko te momo waeine whatu (kitenga i te tīmatanga), me te mea kua whakarerekētia te waeine whatu (kitenga ina huri mai i te āhua kore-mārama ki te āhua mārama); nō reira, ka taea e tēnei mahi auaha te whakawhiti tika i ngā aratau mahi e whai ake nei i runga i te momo waeine whatu o te onu, kia tika ai te mahi.
