This article first is brief introduced the world broadband access network develops the condition and the main application, next narrated the wide band optical fiber access network merit. With emphasis has once more analyzed the wide band point-to-point active Ethernet optical fiber system and the wide band to the passive optical fiber system characteristic and the application. Meets down proposed our country optical fiber access network sends chem. possible to surmount APON, BPON and the EPON stage, starts from the wide band point-to-point Ethernet optical fiber system and GEPON, finally and even transits to the GPON stage preliminary idea. Finally analyzed the optical fiber communications technology trend of development from each angle. [资料来源：http://doc163.com]
