我国通信业“十二五”规划中,已明确将加快信息基础设施建设和推进经济社会各领域信息化作为重要的发展战略之一,而宽带基础设施建设毫无疑问是重中之重。中国电信在过去几年大力实施“光进铜退”、系统推进PON技术规模化应用的基础上,于2011年年初对外宣布全面实施“宽带中国·光网城市”战略,通过铜缆向光纤网络的升级换代,力争到2015年年末在南方城市地区实现家庭和政企用户光纤的全覆盖,光纤入户(FTTH)超过1亿户,位居世界领先地位。可以预见,“宽带中国·光网城市”的深入推进将给电信运营商自身的网络建设以及相关产业的发展带来巨大的机遇与挑战。
China’s telecommunications industry “Twelfth Five-Year Plan”, it has clearly will speed up the construction of information infrastructure and promote economic and social development in all fields as one of the important development strategy, and broadband infrastructure is undoubtedly the most important . Based on the large-scale application of PON technology in the past few years, China Telecom announced the full implementation of its “Broadband China Optical Network City” strategy at the beginning of 2011 through copper Cable upgrade to fiber optic network, and strive to achieve the full coverage of optical fibers for home and business users in southern urban areas by the end of 2015, with over 100 million FTTH subscribers in the world. It is foreseeable that the in-depth promotion of “Broadband China Optical Network City” will bring tremendous opportunities and challenges to the telecom operators’ own network construction and the development of related industries.
