GPON (Gigabit-Capable PON) technology is based on standard ITU-TG.984.x the latest generation of broadband passive optical access standards, with high bandwidth, high efficiency, large coverage, rich user interface and many other advantages, is large Most operators deemed to achieve broadband access network business, comprehensive transformation of the ideal technology.

EPON is the best combination of several technology and network structure. EPON uses multipoint structure, passive optical transmission, offers a variety of services over Ethernet. At present, IP/Ethernet applications accounted for more than 95% of the entire LAN communication, EPON since the economic and efficient use of the above-described structure, will become an end-user access network connecting the most efficient communication method.
