I-HUANET EPON OLT 16 Amachweba

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.

I-OLT inikeza amachweba angu-16 aphansi okuxhumanisa okungu-1000M EPON, 4*GE SFP, 4*GE COMBO port kanye no-2 *10G SFP wokuxhumanisa 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 ukuxhumana okuhlukile kwe-ONU hybrid.

Inzuzo

I-EPON:OLT ilandela izinga lobuchwepheshe le-IEEE802.3ah ne-China telecom.(YD/T 1475-2006

Umthamo: I-PON ngayinye isekela amatheminali afika kwangu-64, lonke idivayisi isekela ama-ONU afika kwangu-256 ngaphansi kokucushwa okugcwele.

I-Uplink: isekela amamojula kagesi nawe-optical, angahlelwa ngendlela eguquguqukayo ngokuya ngamanethiwekhi ahlukene.

Ubukhulu: Ikhasethi le-1U yonga isikhala, ukusetshenziswa kwamandla okuphansi futhi yonga izindleko.

I-Optical Line Protection: isekela lishintsha ngokuzenzakalelayo lapho ulayini ulungisa iphutha.

Ukuthembeka okuphezulu: isekela ukunikezwa kwamandla okumbaxambili (Ukunikezwa kwamandla okuzenzakalelayo okukodwa).
