FTTH (Fiber To The Home) is the mainstream broadband service in Japan, and the number of its subscribers has been increasing. Many of those subscribers are using telephone service, terrestrial digital television service, and video-ondemand service provided by IP networks. Therefore, FTTH systems are increasingly required to have high stability and the same redundancy that a telephone switchboard has. To meet this demand, we have developed the next-generation FTTH technology 10G-EPON (10 Gigabit Ethernet Passive Optical Network) system that provides the protection function to achieve redundancy at the time of maintenance or emergency. It also includes the in-service firmware update function. This paper presents the evaluation results of this system and introduces our approaches to the improvement in maintenance and operation of 10G-EPON system.
