Theknoloji ea GPON (Gigabit-Capable Passive Optical Network) ke thekenoloji e potlakileng, e sebetsang hantle, le e nang le matla a maholo e sebelisoang haholo ho marang-rang a fiber-to-the-home (FTTH) optical access networks. Marang-rang a GPON,OLT (Optical Line Terminal)le ONT (Optical Network Terminal) ke likarolo tse peli tsa mantlha.

Phapang pakeng tsa OLT le ONT mabapi le sebaka sa 'mele le boemo ba karolo: OLT hangata e fumaneha bohareng ba marang-rang, ke hore, ofisi e bohareng, e bapala karolo ea "molaoli". E hokahanya li-ONT tse ngata 'me e ikarabella bakeng sa ho buisana leONTska lehlakoreng la basebelisi, ha ho ntse ho hokahanya le ho laola phetiso ea data. Ho ka boleloa hore OLT ke motheo le moea oa marang-rang a GPON kaofela. ONT e fumaneha pheletsong ea mosebelisi, ke hore, pheletsong ea marang-rang, e bapala karolo ea "lesole".

Liphapang tsa tšebetso:OLT le ONT li na le maikutlo a fapaneng. Mesebetsi e ka sehloohong ea OLT e kenyelletsa ho bokella lintlha, tsamaiso le taolo, hammoho le phetiso le kamohelo ea matšoao a optical. E na le boikarabello ba ho kopanya melaetsa ea data ho tsoa ho basebelisi ba bangata ho netefatsa hore phetiso ea data e sebetsa hantle. Ka nako e ts'oanang, OLT e boetse e sebelisana le li-OLT tse ling le li-ONT ka mekhoa ea puisano ho laola le ho laola marang-rang kaofela. Ho feta moo, OLT e boetse e fetola matšoao a motlakase hore e be lipontšo tsa optical ebe e li romela ka har'a fiber ea optical. Ka nako e ts'oanang, e khona ho amohela lipontšo tsa optical ho tloha ho ONT le ho li fetola hore e be lipontšo tsa motlakase bakeng sa ho sebetsa. Mosebetsi o ka sehloohong oa ONT ke ho fetola matšoao a optical a fetisitsoeng ka likhoele tsa optical ho lipontšo tsa motlakase le ho romela lipontšo tsena tsa motlakase ho lisebelisoa tse fapaneng tsa basebelisi. Ho feta moo, ONT e ka romella, ea kopanya, le ho sebetsana le mefuta e fapaneng ea data ho tsoa ho bareki le ho e romella ho OLT.
Liphapang boemong ba tekheniki:OLT le ONT le tsona li na le liphapang tsa moralo oa hardware le mananeo a software.
