BPON vs EPON vs GPON: A Comparative Analysis
Advertisement
This article compares BPON, EPON, and GPON technologies, highlighting the key differences between them. PON stands for Passive Optical Network, a common access technology used by service providers to deliver internet and other services.
Access networks come in three main types: wireless, fiber, and copper. PON falls under the fiber category.
The following table summarizes the key specifications of BPON, EPON, and GPON as defined by the ITU organization.
