O le a le Gpon?

GPON (Gigabit-Capable PON) tekonolosi o le augatupulaga aupito lata mai lea o fesoʻotaʻiga fesoʻotaʻiga faʻapipiʻi faʻapipiʻi faʻapipiʻi faʻapipiʻi faʻavae i luga o le tulaga ITU-TG.984.x. E tele mea lelei e pei o le maualuga o le bandwidth, maualuga le lelei, tele le faʻapipiʻiina, ma le mauoa o tagata faʻaoga. Ole tele ole aufaipisinisi e manatu ose tekonolosi lelei e fa'ataunu'uina ai feso'ota'iga lautele ma suiga atoatoa ole auaunaga feso'ota'iga avanoa. GPON na muamua faʻatulagaina e le Full-Service Access Network (FSAN) faʻalapotopotoga ia Setema 2002. I luga o lenei faʻavae, ITU-T faʻamaeʻaina le faʻatulagaina o le ITU-TG.984.1 ma le G.984.2 ia Mati 2003. , O le faʻatulagaina o G.984.3 na maeʻa ia Fepuari ma Iuni 2004, ma faʻatupuina ai le aiga masani o le GPON.

O le a le Epon?

EPON (Ethernet Passive Optical Network), e pei ona taʻu mai e le igoa, o se tekonolosi PON faʻavae Ethernet. E faʻaaogaina le faʻasologa-i-multipoint structure, faʻasalalauga faʻapipiʻi opitika, ma tuʻuina atu le tele o auaunaga ile Ethernet. EPON tekinolosi ua fa'ata'atia e le vaega galue IEEE802.3 EFM. Ia Iuni 2004, na tuʻuina atu ai e le vaega galue IEEE802.3EFM le faʻataʻitaʻiga o le EPON - IEEE802.3ah (faʻapipiʻiina i totonu o le IEEE802.3-2005 standard i le 2005). I lenei tulaga, o le Ethernet ma le PON tekinolosi ua tuʻufaʻatasia, o loʻo faʻaogaina le tekonolosi PON i le faʻaogaina o le tino, o le Ethernet protocol o loʻo faʻaaogaina i le faʻasologa o fesoʻotaʻiga faʻamaumauga, ma o le avanoa Ethernet e maua i le faʻaaogaina o le topology PON. O le mea lea, e tuʻufaʻatasia ai le lelei o tekinolosi PON ma Ethernet tekinolosi: tau maualalo, bandwidth maualuga, malosi scalability, fetaui ma Ethernet o loʻo i ai, ma pulega faigofie.
