Ukubuka konke komkhiqizo:
I-EPON OLT iyikhasethi eliphezulu elididiyelwe nelisezingeni eliphakathi i-EPON OLT elakhelwe ukufinyelela kwabaqhubi kanye nenethiwekhi yekhampasi yebhizinisi. Ilandela izindinganiso zobuchwepheshe ze-IEEE802.3 ah futhi ihlangabezana nezimfuneko zemishini ye-EPON OLT ye-YD/T 1945-2006 Izimfuneko Zobuchwepheshe zokufinyelela inethiwekhi——ezisekelwe ku-Ethernet Passive Optical Network (EPON) kanye nezimfuneko zobuchwepheshe ze-China telecom EPON 3.0. Uchungechunge lwe-EPON OLT lunokuvuleka okuhle kakhulu, umthamo omkhulu, ukuthembeka okuphezulu, umsebenzi ophelele wesoftware, ukusetshenziswa okusebenzayo komkhawulokudonsa kanye nekhono lokusekela lebhizinisi le-Ethernet, elisetshenziswa kabanzi ekumbozweni kwenethiwekhi ye-opharetha yangaphambili, ukwakhiwa kwenethiwekhi yangasese, ukufinyelela kwekhampasi yebhizinisi nokunye ukwakhiwa kwenethiwekhi yokufinyelela.
Kunezinhlobo ezimbili zokucaciswa kwe-OLT. I-OLT inikeza amachweba angu-4/8 we-downlink 1.25G EPON, amachweba angu-8 * GE LAN Ethernet kanye namachweba angu-4 *10G SFP wokuxhuma phezulu. Ubude bungu-1U kuphela ukuze kufakwe kalula nokonga isikhala. Yamukela ubuchwepheshe obuthuthukisiwe, obunikeza isixazululo esisebenzayo se-EPON. Ngaphezu kwalokho, yonga izindleko eziningi ku-opharetha ngoba ingakwazi ukusekela i-ONU hybrid networking.
