EPON:OLT amatsatira mulingo waukadaulo wa IEEE802.3ah ndi China telecom.(YD/T 1475-2006） Kuthekera: PON iliyonse imathandizira mpaka ma terminals 64, chipangizo chonsecho chimathandizira mpaka 256 ONUs pokonzekera kwathunthu. Uplink: kuthandizira ma module amagetsi ndi kuwala, amatha kusinthidwa mosinthika malinga ndi maukonde osiyanasiyana. Kukula: Kaseti ya 1U sungani malo, kugwiritsa ntchito mphamvu zochepa ndikusunga mtengo. Optical Line Chitetezo: Thandizo limasintha zokha mzerewo ukangowonongeka. Kudalirika kwakukulu: kumathandizira magetsi apawiri (Kukhazikika kwamagetsi amodzi).Ubwino
