GPON and EPON  have their own advantages. GPON is better than EPON in terms of performance indicators. However, EPON has the advantage of time and cost. GPON is catching up. Looking forward to the future broadband access market may not be a replacement, it should be complementary. For bandwidth, multi-service, high QoS and security requirements, and ATM technology as a backbone customer, GPON will be more suitable. For customers with low cost sensitivity, QoS and security requirements, EPON has become the dominant factor. What is PON? The PON (Passive Optical Network) is the main technology for implementing FTTH fiber-to-the-home. It provides point-to-multipoint fiber access. It consists of the OLT (optical line terminal) on the office side and the ONU (optical network unit) on the user side) and ODN (Optical Distribution Network). Generally, the downlink adopts the TDM broadcast mode and the uplink adopts the TDMA (Time Division Multiple Access) mode to form a point-to-multipoint t
