    IPTV, HDTV, 3D services, and video conferencing are among the applications that epitomize the new ultra-
    broadband era and demand great things from broadband access networks. FTTx has emerged as a high
    capacity, wide coverage, and low cost solution that is eco-friendly and can smoothly bear video services.
    Backed by mature technology, reduced costs, government support, and increasingly open policies, FTTx is
    the new optimum choice for operators.
