BPON vs EPON vs GPON-difference between BPON,EPON and GPON

This page compares BPON vs EPON vs GPON and mention difference between BPON, EPON and GPON.

PON is the short form of Passive Optical Network. It is one of the access type used by the service provider. There are three types of access networks viz. wireless, fiber and copper. Following table summarizes the three types of PON as defined by ITU organization.
