GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) are two competing PON technologies used for FTTH (Fiber to the Home) and FTTx de.
GPON (ITU-T G.984): 2.488 Gbps downstream, 1.244 Gbps upstream. More widely deployed in Europe and Middle East. Supports TDM (Time Division Multiplexing) for voice.
EPON (IEEE 802.3ah): Symmetric 1.25 Gbps both directions. More widely deployed in Asia Pacific. Based on Ethernet, simpler integration with existing networks. Lowe.
Which one to choose: For new residential FTTH deployments, GPON offers higher bandwidth. For enterprise or campus networks with existing Ethernet infrastructure, E.
MarStars manufactures both GPON and EPON ONU/OLT equipment, supporting triple-play services (voice, video, data) for telecom operators and ISPs.
