O le a le FTTH/FTTO?
XGSPON (10 Gigabit Symmetric Passive Optical Network) tekinolosi ua toe faʻafouina fesoʻotaʻiga fiber optic, tuʻuina atu faʻavavevave faʻasalalau faʻamatalaga, faʻateleina le bandwidth ma faʻaleleia le faʻatinoga o fesoʻotaiga.Ina ia ausia le fesoʻotaʻiga lemu ma faʻafetaui le faʻatupulaia o manaʻoga o talosaga faʻaonaponei, o loʻo taumafai pea le auʻaunaga e faʻapipiʻi le sili atu ona lelei ma faʻaogaina laina laina (OLTs).I lenei blog, o le a matou suʻesuʻeina mea fou fou i tekinolosi XGSPON.
GPON (Gigabit Passive Optical Network) faʻavaeina le faʻavae mo fesoʻotaʻiga fiber optic maualuga, sosoo ai ma le XGPON (10 Gigabit PON) lea na maua ai le bandwidth maualuga.Ae ui i lea, o le XGSPON e alu i le laasaga e tasi, e mafai ai ona fua faʻamaumauga tutusa o le 10 Gbps i luga ma lalo o faʻasalalauga, e mafua ai fesoʻotaʻiga vave, sili atu ona faʻalagolago.
I le masani ai, OLTs ua faʻapipiʻiina i nai ports laiti.Ae ui i lea, ina ia faʻafeiloaʻi le faʻateleina o numera o tagata faʻaoga ma masini i le lalolagi fesoʻotaʻi i aso nei, o OLT ma 8 ports ua faʻateleina le lauiloa.O lenei fa'alauteleina o le uafu e mafai ai e kamupani o lo'o tu'uina atu auaunaga ona fa'amalieina le tele o tagata fa'atau, fa'aavanoaina le feso'ota'iga fiber i le tele o tagata ta'ito'atasi ma pisinisi.
Laega 3 galuega faatino:
O le tu'ufa'atasiga o le Layer 3 i totonu o le OLT e tatalaina ai le tele o auala e mafai ai, ma fa'aleleia atili ai le fa'atinoga o feso'otaiga ma pulega.Layer 3 switches e nafa ma le taʻitaʻia o faʻamaumauga faʻamaumauga i luga o fesoʻotaʻiga eseese, faʻalauiloaina lelei le tafe o faʻamatalaga ma faʻaitiitia le faʻaogaina o fesoʻotaiga.E ala i le tu'ufa'atasia o le Layer 3 fa'atinoga i totonu ole OLT, e mafai ai e 'au'aunaga ona fa'amalieina le fa'atinoga o feso'otaiga, fa'amautinoa le lelei o fa'asologa o fa'amaumauga, ma fa'aleleia atili le poto masani o tagata fa'aoga.
O le OLT aupito lata mai o lo'o tu'ufa'atasia le tekonolosi XGSPON ma le 8 ports ma le Layer 3 fa'atinoga, e ofoina atu le tele o fa'amanuiaga.E mafai e 'au'aunaga ona fiafia i le fa'ateleina o le malosi o tagata fa'aoga, fa'aleleia atili le lelei o feso'otaiga ma fa'afaigofie le pulega.O tagata fa'ai'uga, i le isi itu, e mafai ona o'o i saosaoa i luga ole laiga, feso'ota'iga fa'atuatuaina, ma fa'aleleia atili le fa'atinoga mo fa'amatalaga fa'amautu fa'amaumauga e pei o le fa'asalalauina o vitio, ta'aloga i luga ole laiga, ma tautua ao.
A'o fa'aauau pea le aga'i i luma o tekonolosi, o lo'o fa'aauau pea ona fa'atupula'ia le mana'omia mo feso'ota'iga televave ma fa'atuatuaina.Tekinolosi XGSPON, faʻatasi ai ma lona faʻalauteleina o faʻamatalaga faʻamatalaga gafatia, faʻatasi ai ma OLT lata mai ma le 8-taulaga ma le Layer 3 gafatia, e maua ai se fofo faʻamalosi e faʻafetaui nei manaʻoga.E ala i le faʻaaogaina o nei faʻafouga, e mafai ai e le auʻaunaga ona faʻafetaui le faʻatupulaia o manaʻoga o fesoʻotaʻiga faʻaonaponei, tuʻuina atu i tagata faʻatau le faʻatinoga o fesoʻotaʻiga sili atu ma se poto masani faʻaoga le mafaatusalia.
