Theknoloji ea GPON (Gigabit-Capable PON) ke moloko oa morao-rao oa theknoloji ea phihlello e kopaneng ea Broadband passive optical ho latela maemo a ITU-TG.984.x.E na le melemo e mengata joalo ka bandwidth e phahameng, ts'ebetso e phahameng, tšireletso e kholo, le lihokelo tse ruileng tsa basebelisi.Basebelisi ba bangata ba e nka e le thekenoloji e nepahetseng ea ho fumana li-broadband le phetoho e felletseng ea lits'ebeletso tsa marang-rang.GPON e ile ea qalisoa ka lekhetlo la pele ke mokhatlo o hlophisitsoeng oa Full-Service Access Network (FSAN) ka September 2002. Motheong ona, ITU-T e phethile tlhahiso ea ITU-TG.984.1 le G.984.2 ka March 2003. , The standardization of G.984.3 e ile ea phethoa ka February le June 2004, kahoo ea theha lelapa le tloaelehileng la GPON.

EPON (Ethernet Passive Optical Network), joalo ka ha lebitso le bontša, ke theknoloji ea PON e thehiloeng ho Ethernet.E amohela sebopeho sa ntlha-to-multipoint, phetiso ea fiber optical passive, mme e fana ka lits'ebeletso tse fapaneng ho Ethernet.Theknoloji ea EPON e emetsoe ke sehlopha se sebetsang sa IEEE802.3 EFM.Ka Phuptjane 2004, sehlopha se sebetsang sa IEEE802.3EFM se ile sa lokolla maemo a EPON - IEEE802.3ah (e kenyellelitsoeng ho IEEE802.3-2005 ka 2005).Ka mokhoa ona, theknoloji ea Ethernet le PON e kopantsoe, theknoloji ea PON e sebelisoa karolong ea 'mele, protocol ea Ethernet e sebelisoa lera la khokahanyo ea data,' me ho fihlella Ethernet ho fumanoa ka ho sebelisa PON topology.Ka hona, e kopanya melemo ea theknoloji ea PON le theknoloji ea Ethernet: theko e tlaase, bandwidth e phahameng, scalability e matla, ho lumellana le Ethernet e teng, le tsamaiso e bonolo.
