CCSA (China’s Communications Standards Association) has added 2.5G EPON as a standard specification for fiber-based broadband access networks. CCSA’s adoption of 2.5G EPON is intended to enable service providers to offer more bandwidth per subscriber for MDUs, including residential and business subscribers.
China is poised to surpass Japan with the largest number of fiber subscribers by year-end. China ended 2008 with more than 8 million FTTx subscribers and is expected to reach more than 20 million fiber subscribers by year-end 2009. EPON is a dominant fiber architecture, accounting for more than 95 percent of the existing and planned deployments.
