Amachweba e-HUANET EPON OLT 16
I-EPON OLT iyikhasethi yokuhlanganiswa okuphezulu kanye nomthamo ophakathi I-EPON OLT eyenzelwe ukufinyelela kwabaqhubi kanye nenethiwekhi yekhampasi yebhizinisi.
Ilandela amazinga obuchwepheshe e-IEEE802.3 ah futhi ihlangabezana nezidingo zemishini ye-EPON OLT ye-YD/T 1945-2006 Izidingo zobuchwepheshe zenethiwekhi yokufinyelela——ezisekelwe ku-Ethernet Passive Optical Network (EPON) kanye nezimfuneko zobuchwepheshe ze-China telecom EPON 3.0.
I-OLT inikeza amachweba angu-16 e-downlink angu-1000M EPON, ichweba le-4*GE SFP, ichweba le-4*GE COMBO kanye ne-2 *10G SFP ye-uplink. Ukuphakama kungama-1U kuphela ukuze kube lula ukufaka nokonga isikhala. Isebenzisa ubuchwepheshe obuthuthukisiwe, inikeza isisombululo se-EPON esisebenzayo. Ngaphezu kwalokho, yonga izindleko eziningi kubasebenzisi ngoba ingasekela inethiwekhi ehlukene ye-ONU hybrid.

I-EPON:OLT ilandela izinga lobuchwepheshe le-IEEE802.3ah kanye ne-China telecom.(I-1965)I-YD/T 1475-2006） Umthamo: I-PON ngayinye isekela ama-terminal afinyelela ku-64, yonke idivayisi isekela ama-ONU afinyelela ku-256 ngaphansi kokucushwa okugcwele. I-Uplink: isekela amamojula kagesi nawe-optical, angalungiswa kalula ngokuya ngenethiwekhi ehlukene. Ubukhulu: Ikhasethi engu-1U yonga isikhala, ukusetshenziswa kwamandla okuphansi kanye nezindleko zokonga. Ukuvikelwa Komugqa Obonakalayo: ukwesekwa kushintsha ngokuzenzakalelayo lapho umugqa ulungiswa. Ukuthembeka okuphezulu: kusekela ukunikezwa kwamandla okubili (Ukunikezwa kwamandla okukodwa okuzenzakalelayo).Inzuzo
