Madoko a HUANET EPON OLT 16
EPON OLT ndi kaseti yolumikizirana kwambiri komanso yapakatikati ya EPON OLT yopangidwira mwayi wofikira kwa ogwira ntchito komanso netiweki ya masukulu amakampani.
Imatsatira miyezo yaukadaulo ya IEEE802.3 ah ndipo imakwaniritsa zofunikira za zida za EPON OLT za YD/T 1945-2006 Zofunikira zaukadaulo pa netiweki yolowera——zochokera pa Ethernet Passive Optical Network (EPON) ndi zofunikira zaukadaulo za EPON 3.0.
OLT imapereka madoko 16 a downlink 1000M EPON, 4 * GE SFP, 4 * GE COMBO doko ndi 2 * 10G SFP ya uplink. Kutalika kwake ndi 1U yokha kuti kukhazikike mosavuta komanso kusunga malo. Imagwiritsa ntchito ukadaulo wapamwamba, womwe umapereka yankho labwino la EPON. Kuphatikiza apo, imasunga ndalama zambiri kwa ogwiritsa ntchito chifukwa imatha kuthandizira maukonde osiyanasiyana a ONU hybrid.

EPON:OLT ikutsatira muyezo waukadaulo wa IEEE802.3ah ndi China telecom.(a)YD/T 1475-2006） Kuthekera: PON iliyonse imathandizira ma terminal okwana 64, chipangizo chonsecho chimathandizira ma ONU okwana 256 omwe ali pansi pa dongosolo lonse. Uplink: imathandizira ma module amagetsi ndi optical, amatha kusinthidwa mosinthasintha malinga ndi maukonde osiyanasiyana. Kukula: Kaseti ya 1U isunga malo, kugwiritsa ntchito mphamvu zochepa komanso kusunga ndalama. Chitetezo cha Mzere Wowoneka: chithandizo chimasintha chokha pamene mzerewo wasinthidwa. Kudalirika kwakukulu: kumathandizira magetsi awiri (magetsi amodzi okhazikika).Ubwino
