EPON ndiukadaulo wa PON wozikidwa pa Ethernet. Imagwiritsa ntchito ukadaulo wa PON pagawo lakuthupi, Ethernet protocol pagawo lolumikizira deta, kulumikizana kwa Ethernet pogwiritsa ntchito PON topology, komanso mwayi wopezeka ndi data, mawu, ndi makanema pogwiritsa ntchito kuwala. Kufotokozera kwazinthu za EPON: EPON imatumiza ndikulandila ...

The optical splitter ndi chimodzi mwazinthu zofunika kungokhala chete mu ulalo wa fiber optical, ndipo makamaka amasewera gawo logawanika. Nthawi zambiri amagwiritsidwa ntchito mu optical line terminal OLT ndi optical network terminal ONU ya passive optical network kuti azindikire kugawanika kwa chizindikiro. The op...

Pakalipano, ponena za teknoloji ya optical fiber access network, kupeza kwa narrowband pang'onopang'ono kumasinthidwa ndi mwayi wa burodibandi, ndipo pamapeto pake fiber home imatheka. Broadband Optical fiber ya netiweki yofikira imakhala yosapeŵeka, ndipo ukadaulo wa PON udzakhala malo aukadaulo a ...

PON gawo ndi mkulu-ntchito Optical module ntchito PON dongosolo, Amatchedwa PON gawo, kutsatira ITU-T G.984.2 muyezo ndi Mipikisano gwero mgwirizano (MSA),Imagwiritsa ntchito mafunde osiyanasiyana kutumiza ndi kulandira zizindikiro pakati OLT (Optical Line Terminal) ndi ONT (Optical Network Terminal).
