EPON: Ua hahai ʻo OLT i ke kūlana ʻenehana o IEEE802.3ah a me Kina telecom.（YD/T 1475-2006） Kaha: Kākoʻo kēlā me kēia PON a hiki i ka 64 terminals, kākoʻo ka hāmeʻa holoʻokoʻa a hiki i 256 ONU ma lalo o ka hoʻonohonoho piha. Uplink: kākoʻo i nā modula uila a me ka optical, hiki ke hoʻonohonoho maʻalahi e like me ka pūnaewele ʻokoʻa. Ana: 1U cassette e mālama i ka lewa, haʻahaʻa ka hoʻohana mana a mālama i ke kumukūʻai.
