Comprehensive comparison of EPON and GPON technology
1. EPON and GPON technology EPON (Ethernet Passive Optical Network) is an Ethernet-based PON technology. It uses point-to-multipoint architecture, passive fiber transmission, and provides multiple services over Ethernet. GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interface, etc. Most operators regard it as an ideal technology for achieving broadband and integrated transformation of access network services. 2. EPON and GPON rate EPON provides fixed uplink and downlink 1.25 Gbps, 8b/10b line coding, and an actual rate of 1Gbps. GPON supports multiple speed grades, can support uplink and downlink asymmetric speed, downlink 2.5Gbps or 1.25Gbps, uplink 1.25Gbps or 622 Mbps.According to actual needs, the uplink and downlink rates are determined, and the corresponding optical modules are se
