I roto i te ao o te Whatunga Whakawhitiwhiti Kōrero o ēnei rā, kua nohoia e te hangarau Whatunga Whatu Āhuakore (PON) tētahi tūranga nui i roto i te whatunga whakawhitiwhiti kōrero matua me ōna painga o te tere tere, te tawhiti tawhiti, me te kore haruru. I roto i ēnei, ko te GPON, te XG-PON me te XGS-PON ngā hangarau whatunga whatu āhuakore e tino arohia ana. He āhuatanga motuhake ō rātou, ā, he whānuitia te whakamahinga i roto i ngā āhuatanga rerekē. Ka tirohia e tēnei tuhinga ngā rerekētanga matua i waenga i ēnei hangarau e toru kia pai ake ai te mārama o ngā kaipānui ki ō rātou āhuatanga me ngā āhuatanga tono.
Ko te GPON, ko te ingoa katoa ko Gigabit-CapablePassive OpticalNetwork, he hangarau whatunga whatu kore mahi i tūtohutia tuatahitia e te whakahaere FSAN i te tau 2002. Whai muri i ētahi tau o te whanaketanga, i whakamanahia e te ITU-T i te tau 2003. Ko te hangarau GPON he mea hanga mō te mākete whatunga urunga, ka taea te whakarato ratonga raraunga, reo me te ataata tere-tere me te kaha-nui mō ngā whānau me ngā umanga.
Ko ngā āhuatanga o te hangarau GPON e whai ake nei:
1. Tere: ko te tere tuku iho ko 2.488Gbps, ko te tere tuku iho ko 1.244Gbps.
2. Ōwehenga whakawhiti: 1:16/32/64.
3. Tawhiti tuku: ko te tawhiti tuku mōrahi he 20km.
4. Hōputu whakakōpaki: Whakamahia te hōputu whakakōpaki GEM (GEM Encapsulation Method).
5. Tikanga tiaki: Whakamahia te tikanga whakawhiti tiaki korekore 1+1, 1:1 rānei.
Ko XG-PON, te ingoa katoa o 10Gigabit-CapablePassive OpticalNetwork, te whakatupuranga hou o te hangarau GPON, e mōhiotia ana ko te whatunga whatu kore mahi o te whakatupuranga hou (NG-PON). Ki te whakatauritea ki te GPON, he nui ngā whakapainga o te XG-PON i roto i te tere, te ōwehenga whakawhiti me te tawhiti tuku.
Ko ngā āhuatanga hangarau XG-PON e whai ake nei:
1. Tere: Ko te tere tuku hononga-iho he 10.3125Gbps, ko te tere tuku hononga-ake he 2.5Gbps (ka taea hoki te whakapai ake i te hononga-ake ki te 10 GBPS).
2. Ōwehenga whakawhiti: 1:32/64/128.
3. Tawhiti tuku: ko te tawhiti tuku mōrahi he 20km.
4. Hōputu mōkihi: Whakamahia te hōputu mōkihi GEM/10GEM.
5. Tikanga tiaki: Whakamahia te tikanga whakawhiti tiaki korekore 1+1, 1:1 rānei.
Ko XGS-PON, e mōhiotia ana ko te 10GigabitSymmetric Passive OpticalNetwork, he putanga ōrite o XG-PON, i hangaia hei whakarato ratonga urunga whānui me ngā reiti ōrite o runga me raro. Ki te whakatauritea ki te XG-PON, he nui ake te tere o te hononga ake o XGS-PON.
Ko ngā āhuatanga hangarau XGS-PON e whai ake nei:
1. Tere: Ko te tere tuku iho ko 10.3125Gbps, ko te tere tuku iho ko 10 GBPS.
2. Ōwehenga whakawhiti: 1:32/64/128.
3. Tawhiti tuku: ko te tawhiti tuku mōrahi he 20km.
4. Hōputu mōkihi: Whakamahia te hōputu mōkihi GEM/10GEM.
5. Tikanga tiaki: Whakamahia te tikanga whakawhiti tiaki korekore 1+1, 1:1 rānei.
Whakatau: Ko te GPON, te XG-PON me te XGS-PON ngā hangarau whatunga whatu kore mahi matua e toru. He rerekētanga mārama kei roto i te tere, te ōwehenga whakawhiti, te tawhiti tuku, me ētahi atu, hei whakatutuki i ngā hiahia o ngā horopaki tono rerekē.
Ina koa: Ko te GPON te mea nui mō te mākete whatunga urunga, e whakarato ana i ngā raraunga tere-teitei, te kaha-nui, te reo me te ataata me ētahi atu ratonga; Ko te XG-PON he putanga whakapai ake o te GPON, he tere ake, he ngāwari ake te ōwehenga whakawhiti. Ka whakanuia e te XGS-PON te ōritetanga o ngā reiti whakarunga me te whakararo, ā, he pai mō ngā tono whatunga hoa-ki-hoa. Mā te mārama ki ngā rerekētanga matua i waenga i ēnei hangarau e toru ka āwhina i a tātou ki te whiriwhiri i te otinga whatunga whatu tika mō ngā āhuatanga rerekē.
