Aotelega o tekinolosi PON ma ana mataupu faavae networking: O lenei tusiga o loʻo faʻalauiloaina muamua le manatu, galuega faʻavae ma uiga o tekinolosi PON, ona faʻatalanoaina lea i auiliiliga o le faʻavasegaina o tekinolosi PON ma ona uiga faʻaoga i le FTTX.O le taulaiga o le tusiga o le faʻamalamalamaina o mataupu faavae o fesoʻotaʻiga e manaʻomia ona mulimulitaʻia i le PON tekinolosi fesoʻotaʻiga fuafuaga e taʻitaʻia ai le fausiaina o fesoʻotaʻiga ma galuega faʻaleleia.

1. Vaʻaiga lautele o le PON tekinolosi PON (Passive Optical Network, Passive Optical Network) tekinolosi o se tekinolosi fesoʻotaʻiga e faʻaogaina ai le fiber opitika e pei o le faʻaogaina o fesoʻotaʻiga ma iloa ai le tuʻuina atu o faʻamatalaga e ala i masini faʻaoga passive.O tekonolosi PON o loʻo i ai le lelei o le mamao faʻasalalau, maualuga bandwidth, malosi malosi faʻalavelave faʻalavelave, ma le tau maualalo o le tausiga, o lea na faʻaaogaina lautele i le fanua o fesoʻotaʻiga avanoa.Ole fesoʻotaʻiga PON e masani ona aofia ai vaega e tolu:OLT(Optical Line Terminal, optical line terminal), ONU (Optical Network Unit, optical network unit) ma ODN (Optical Distribution Network, optical distribution network).
2. fa'avasegaina tekinolosi PON ma uiga fa'aoga i le tekonolosi FTTX PON e masani ona vaevaeina i ni ituaiga se lua: EPON (Ethernet PON, Ethernet Passive Optical Network) maGPON(Gigabit-Capable PON, Gigabit Passive Optical Network).EPON e faʻavae i luga o le Ethernet protocol, e maualuga le fesoʻotaʻiga ma fetuutuunai, ma e talafeagai mo le tele o faʻataʻitaʻiga pisinisi.GPON o loʻo i ai le televave o fesoʻotaʻiga ma le gafatia o le lagolago o auaunaga, ma e talafeagai mo faʻataʻitaʻiga e maualuga le bandwidth ma manaʻoga QoS.I FTTX (Fiber To The X) talosaga, PON tekinolosi e taua tele.FTTX o lo'o fa'atatau i se fausaga feso'ota'iga e tu'u ai alava mata i tafatafa o fale fa'aoga po'o mea fa'aoga.E tusa ai ma laʻasaga eseese o le faʻapipiʻiina o fiber, FTTX e mafai ona vaevaeina i ni ituaiga eseese e pei o le FTTB (Fiber To The Building) ma le FTTH (Fiber To The Home).I le avea ai o se tasi o auala taua o le faʻatinoga o le FTTX, o le PON technology e tuʻuina atu ai i tagata faʻaoga fesoʻotaʻiga televave ma mautu.
3. PON technology networking principles I le PON technology network planning, e tatau ona mulimulitaʻia mataupu faavae o fesoʻotaʻiga nei:
O le fausaga o fesoʻotaʻiga e faigofie ma lelei:e tatau ona fa'aitiitia le tele o feso'otaiga ma le numera o nodes e fa'aitiitia ai le lavelave o feso'otaiga ma tau o le tausiga.I le taimi lava e tasi, e manaʻomia le faʻamautinoaina o le fesoʻotaʻiga e maualuga le faʻatuatuaina ma le mautu e faʻafetaui ai manaʻoga faʻapisinisi.
Malosiaga gafatia tau pisinisi:O feso'ota'iga PON e tatau ona i ai le bandwidth maualuga ma le QoS fa'amautinoaga gafatia e fa'afetaui ai mana'oga fa'atupulaia o pisinisi.I le taimi lava e tasi, e manaʻomia le lagolagoina o le tele o ituaiga pisinisi ma le faʻaogaina o masini faʻapipiʻi e ausia ai le tuʻufaʻatasia o pisinisi ma pulega faʻatasi.
Saogalemu maualuga:O fesoʻotaʻiga PON e tatau ona faʻaaogaina le tele o auala saogalemu e faʻamautinoa ai le le faalauaiteleina, faʻamaoni ma le maua o faʻamatalaga faʻamatalaga.Mo se fa'ata'ita'iga, e mafai ona fa'aoga auala e puipuia ai e pei o le fa'ailoga fa'ailoga ma le fa'atonutonuina o avanoa e puipuia ai osofa'iga o feso'otaiga ma fa'amaumauga.
Malosi fa'afuafua:O fesoʻotaʻiga PON e tatau ona i ai le faʻaleleia lelei ma mafai ona faʻafetaui i suiga i manaʻoga pisinisi i le lumanaʻi ma atinaʻe tekonolosi.Mo se faʻataʻitaʻiga, e mafai ona faʻalauteleina le tele o fesoʻotaʻiga ma faʻasalalauga e ala i le faʻaleleia o meafaigaluega OLT ma ONU poʻo le faʻaopoopoina o nodes ODN.
Le fetaui lelei:O fesoʻotaʻiga PON e tatau ona lagolagoina le tele o tulaga ma faʻasalalauga ma mafai ona faʻafesoʻotaʻi lelei ma fesoʻotaʻi faʻatasi ma fesoʻotaʻiga ma meafaigaluega.E fesoasoani lea i le fa'aitiitia o tau o le fausiaina ma le tausiga o feso'otaiga ma fa'aleleia atili le fa'aogaina ma le fa'amaoni.
4.Fa'ai'uga PON tekinolosi, e pei o se fa'aogaina lelei ma fa'atuatuaina le fa'aogaina o le fiber optical technology, o lo'o i ai fa'amoemoega fa'aoga lautele i le tulaga o feso'ota'iga avanoa.E ala i le mulimulitaia o mataupu faavae mo fesoʻotaʻiga fesoʻotaʻiga ma faʻataʻitaʻiga, o le faʻatinoga ma le faʻamautuina o le fesoʻotaʻiga PON e mafai ona faʻaleleia atili e faʻafetaui ai manaoga faʻatupulaia pisinisi o tagata faʻaoga.I le taimi lava e tasi, faʻatasi ai ma le faʻaauau pea o le alualu i luma o tekinolosi ma le faʻaauau pea o le faʻalauteleina o faʻataʻitaʻiga o faʻataʻitaʻiga, o le a sili atu ona taua le sao a le PON i le lumanaʻi.
