Yintoni iGpon?

I-GPON (i-Gigabit-Capable PON) iteknoloji yisizukulwana samva nje se-broadband passive optical access access technology esekelwe kumgangatho we-ITU-TG.984.x.Ineenzuzo ezininzi ezinje nge-bandwidth ephezulu, ukusebenza kakuhle okuphezulu, ukugubungela okukhulu, kunye nojongano lomsebenzisi otyebileyo.Uninzi lwabasebenzisi luyijonga njengetekhnoloji efanelekileyo yokufumana ibroadband kunye nenguqu ebanzi yokufikelela kwiinkonzo zenethiwekhi.I-GPON yaqala ukucetyiswa ngumbutho we-Full-Service Access Network (FSAN) ngoSeptemba 2002. Ngesi siseko, i-ITU-T yagqiba ukuqulunqwa kwe-ITU-TG.984.1 kunye ne-G.984.2 ngo-Matshi 2003. , Ukumiswa kwe-G.984.3 yagqitywa ngoFebruwari nangoJuni 2004, ngaloo ndlela yenza usapho oluqhelekileyo lweGPON.

Yintoni uEpon?

I-EPON (i-Ethernet Passive Optical Network), njengoko igama libonisa, iteknoloji ye-PON esekelwe kwi-Ethernet.Yamkela i-point-to-multipoint structure, i-passive optical fiber transmission, kwaye inikezela ngeenkonzo ezahlukeneyo kwi-Ethernet.Itekhnoloji ye-EPON ibekwe emgangathweni liqela elisebenzayo le-IEEE802.3 EFM.NgoJuni 2004, iqela elisebenzayo le-IEEE802.3EFM likhuphe umgangatho we-EPON - IEEE802.3ah (ifakwe kumgangatho we-IEEE802.3-2005 ngo-2005).Kulo mgangatho, iteknoloji ye-Ethernet kunye ne-PON zidibaniswe, iteknoloji ye-PON isetyenziswe kwinqanaba lomzimba, i-Ethernet protocol isetyenziswe kwi-data link layer, kunye nokufikelela kwe-Ethernet kufezekiswa ngokusebenzisa i-PON topology.Ngoko ke, idibanisa iingenelo zeteknoloji yePON kunye neteknoloji ye-Ethernet: ixabiso eliphantsi, i-bandwidth ephezulu, i-scalability eyomeleleyo, ukuhambelana ne-Ethernet ekhoyo, kunye nokulawula okulula.
