Iizibuko zeHUANET EPON OLT 16
I-EPON OLT yikhasethi yokudibanisa ephezulu kunye nomthamo ophakathi ye-EPON OLT eyenzelwe ukufikelela kwabaqhubi kunye nenethiwekhi yekhampasi yeshishini.
Ilandela imigangatho yobugcisa ye-IEEE802.3 ah kwaye ihlangabezana neemfuno zezixhobo ze-EPON OLT ze-YD/T 1945-2006 Iimfuno zobugcisa zenethiwekhi yokufikelela——ezisekelwe kwi-Ethernet Passive Optical Network (EPON) kunye neemfuno zobugcisa ze-EPON 3.0 ze-telecom zaseTshayina.
I-OLT inika ii-downlink ezili-16 ze-1000M EPON ports, i-4 * GE SFP, i-4 * GE COMBO port kunye ne-2 * 10G SFP ye-uplink. Ukuphakama yi-1U kuphela ukuze kube lula ukufaka kunye nokonga indawo. Isebenzisa ubuchwepheshe obuphambili, inikezela ngesisombululo se-EPON esisebenzayo. Ngaphezu koko, igcina iindleko ezininzi kubaqhubi kuba inokuxhasa uthungelwano oluhlukeneyo lwe-ONU hybrid.

I-EPON:OLT ilandela umgangatho wobuchwephesha we-IEEE802.3ah kunye ne-China telecom.(IsiNgesi)YD/T 1475-2006） Ubungakanani: I-PON nganye ixhasa ukuya kuthi ga kwii-terminals ezingama-64, isixhobo sonke sixhasa ukuya kuthi ga kwi-256 ONUs phantsi koqwalaselo olupheleleyo. I-Uplink: ixhasa iimodyuli zombane neze-optical, zinokulungiswa ngokuguquguquka ngokwenethiwekhi ezahlukeneyo. Ubukhulu: Ikhasethi eyi-1U yonga indawo, ukusetyenziswa kwamandla okuphantsi kunye neendleko zokonga. Ukhuseleko loMgca obonakalayo: inkxaso itshintsha ngokuzenzekelayo xa umgca ulungiswa. Ukuthembeka okuphezulu: kuxhasa umbane ombini (umbane omnye omiselweyo).Inzuzo
