Isishwankathelo seMveliso:
I-EPON OLT luhlanganiso oluphezulu kunye nomthamo ophakathi wekhasethi EPON OLT eyenzelwe ukufikelela kubaqhubi kunye nothungelwano lwekhampasi yoshishino. Ilandela imigangatho yezobugcisa ye-IEEE802.3 ah kwaye ihlangabezana neemfuno zezixhobo ze-EPON OLT ze-YD / T 1945-2006 Iimfuno zobuchwephesha bokufikelela kwinethiwekhi--ngokusekelwe kwi-Ethernet Passive Optical Network (EPON) kunye ne-China telecom EPON iimfuno zobugcisa ze-3.0. Uchungechunge lwe-EPON OLT lunokuvuleleka okugqwesileyo, umthamo omkhulu, ukuthembeka okuphezulu, umsebenzi opheleleyo wesoftware, ukusetyenziswa ngokufanelekileyo kwebhanwidth kunye nesakhono senkxaso yeshishini le-Ethernet, isetyenziswa ngokubanzi kumnatha we-front-end coverage, ukwakhiwa kwenethiwekhi yabucala, ukufikelela kwikhampasi yeshishini kunye nolunye ulwakhiwo lwenethiwekhi yokufikelela.
Kukho iintlobo ezimbini zeenkcazo OLT. I-OLT inikezela nge-4/8 downlink 1.25G EPON port, 8 * GE LAN Ethernet port kunye ne-4 * 10G SFP ye-uplink. Ubude yi-1U kuphela yofakelo olulula kunye nokugcina indawo. Yamkela itekhnoloji ephezulu, ibonelela ngesisombululo esisebenzayo se-EPON. Ngapha koko, igcina iindleko ezininzi kubaqhubi kuba inokuxhasa uthungelwano oluxutyiweyo lwe-ONU.
