GPON relies on the ITU-T G.984 standard, using GPON Encapsulation Method (GEM) frames to transport Ethernet, TDM, and POTS traffic. EPON relies on the IEEE 802.3ah standard, treating all data natively as Ethernet packets.
Or so it was thought.
GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) are two different technologies used in FTTH networks to provide high-speed internet connectivity. Both technologies use optical fibers to transmit data, but they differ in their architecture and protocols.
