1.EPON和GPON采用不同的标准。可以说GPON比EPON更先进，可以传输更大的带宽，可以承载更多的用户。 GPONoriginatedfromtheAPON\BPONtechnologyintheearlydaysofopticalfibercommunication.Ithasdevelopedfromthis.ThetransmissioncodestreamusesATMframes.Fromthedifferencebetweenthedominantparties,itcanbeinferredthatoperatorsarenaturallyclosertoGPON.Therefore,mostoperatorsaroundtheworldwillchooseGPONastheirOpticalnetworktechnology;EPONismorecloselyrelatedtoEthernet(whichisnowthemostmainstreamcampusnetworktechnology).Thiscanalsobeseenfromthefollowing
