O le a le Gpon?

GPON (Gigabit-Capable PON) tekonolosi o le augatupulaga aupito lata mai lea o fesoʻotaʻiga fesoʻotaʻiga faʻapipiʻi faʻapipiʻi fesoʻotaʻiga 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 faʻaogaina, tele o faʻasalalauga, ma le tamaoaiga faʻaoga 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 faʻaaogaina le tekonolosi PON i le faʻaogaina o le tino, o le Ethernet protocol o loʻo faʻaaogaina i le faʻaogaina o fesoʻotaʻiga faʻamaumauga, ma o le avanoa Ethernet e maua i le faʻaaogaina o le PON topology.O le mea lea, e tuʻufaʻatasia ai le lelei o tekinolosi PON ma tekonolosi Ethernet: tau maualalo, bandwidth maualuga, faʻamalosia malosi, fesoʻotaʻiga ma Ethernet o loʻo iai, ma faigofie pulega.
