Idan baku san bambance-bambancen da ke tsakanin EPON Vs GPON ba yana da sauƙi ku rikice yayin siye. Ta wannan labarin bari mu koyi menene EPON, menene GPON, kuma wanne ne zamu saya?
Menene EPON?
Ethernet m na gani cibiyar sadarwa shi ne cikakken nau'i na acronym EPON. EPON hanya ce ta haɗa kwamfutoci a kan hanyoyin sadarwar sadarwa daban-daban. Ya bambanta da EPON, GPON yana aiki akan ƙwayoyin ATM. An bambanta EPON da GPON ta wannan hanya. Aiwatar da Ingantattun Fakitin Sama da Ƙwararrun hanyoyin sadarwa na Bandwidth (EPON) a cikin Fiber zuwa Filaye da Fiber zuwa Tsarin Gida. EPON yana ba da damar wurare masu yawa don sadarwa akan fiber na gani guda ɗaya. EPON tana watsa bayanai, sauti, da bidiyo akan Intanet ta fakitin Ethernet.
