1. He kupu whakataki poto mō te wehewehe whatu PLC
He taputapu tohatoha mana whatu arataki ngaru whakauru te wehewehe PLC, e hangai ana ki tētahi paparanga kuata. Kei roto i tēnei he hiku poaka, he maramara matua, he rarangi muka whatu, he anga (pouaka ABS, he paipa maitai), he hononga me ngā taura whatu, me ētahi atu. I runga i te hangarau arataki ngaru whatu papatahi, ka hurihia te tāuru whatu ki ngā putanga whatu maha kia ōrite mā te tukanga hononga tika.
Ko ngā āhuatanga o te momo wehewehenga whatu arataki-ngaru papatahi (PLC) he iti te rahi, he whānui te whānuitanga o ngā roangaru mahi, he tino pono, ā, he pai te ōrite o te wehewehenga whatu. He tino pai mō te hono i te tari matua i roto i ngā whatunga whatu kore mahi (EPON, BPON, GPON, me ētahi atu) me ngā taputapu pūrua, me te whakatutuki i te peka o te tohu whatu. E rua ngā momo i tēnei wā: 1xN me 2xN. Ka whakauru ōrite ngā wehewehenga 1×N me 2XN i ngā tohu whatu mai i ngā urunga kotahi, takirua rānei ki ngā putanga maha, ka mahi whakamuri rānei ki te whakakotahi i ngā tohu whatu maha ki roto i ngā muka whatu kotahi, takirua rānei.
2. Te hanganga o te wehewehe muka PLC
Ko te wehewehe PLC whatu tētahi o ngā wāhanga kore mahi nui rawa atu o te hononga muka whatu. He mahi nui tāna i roto i te whatunga whatu kore mahi FTTH. He taputapu takirua muka whatu me ngā pito whakauru maha me ngā pito whakaputa maha. Ko ōna wāhanga matua e toru ko te pito whakauru, te pito whakaputa me te maramara o te rarangi muka whatu. Ko te hoahoa me te huihuinga o ēnei wāhanga e toru he mahi nui ki te whakarite kia taea e te wehewehe whatu PLC te mahi pumau me te mahi noa i muri mai.
1) Hanganga tāuru/tāpui
Kei roto i te hanganga tāuru/tāpui he pereti uhi, he papa, he muka whatu, he wāhi piri ngohengohe, me te wāhi piri mārō.
Wāhi kāpia ngohengohe: Hei whakapiri i te muka whatu ki te taupoki me te raro o te FA, me te tiaki hoki i te muka whatu mai i te kino.
Wāhi kāpia mārō: Whakapiria te taupoki FA, te pereti raro me te muka whatu ki te awaawa-V.
2) Maramara SPL
Kei roto i te maramara SPL he maramara me he pereti taupoki. E ai ki te maha o ngā hongere tāuru me te tāputa, ka wehea kia 1×8, 1×16, 2×8, me ētahi atu. E ai ki te koki, ka wehea kia +8° me -8° ngā maramara.
3. Te hangarau whakaputa o te wehewehe PLC whatu
Ko te wehewehe PLC he mea hanga mā te hangarau semiconductor (te tuhi, te whakairo, te whakawhanake, me ētahi atu). Kei te mata o runga o te maramara te rarangi arataki ngaru whatu, ā, kua whakauruhia te mahi whakawhiti ki runga i te maramara. Ko te tikanga kia tutuki te wehewehenga 1:1 ōrite i runga i te maramara. Kātahi ka honoa te pito whakauru me te pito putanga o te rarangi muka whatu maha-hongere ki ngā pito e rua o te maramara, ā, ka tākaihia.
