最新统计数据表明,今年邮电通信固定资产投资将超过1500亿元,比上年增加投资两成以上。今年通信固定资产投资中,将有900多亿元用于购买国内生产的产品。今年通信投资的重点是干线光缆建设和扩容、移动通信建设、本地网建设。为进一步加快网络的技术改造,今年通信部门将采用波分复用技术(WDM),使目前光缆干线传输速率提高8倍。近两年,我国将在长达3万公里、18条光缆干线上,主要采用8X2.5Gbps 波分复用技术进行扩容改造。今年将完成约2万公里,13条干线光缆的技术改造,还将重点完成西安——合肥、呼和浩特——太原——南宁——北海、兰州——西宁——
The latest statistics show that this year’s post and telecommunications investment in fixed assets will exceed 150 billion yuan, an increase of more than 20% over the previous year’s investment. In this year’s investment in fixed assets, there will be more than 90 billion yuan used to purchase domestically produced products. The focus of this year’s communications investment is the trunk cable construction and expansion, construction of mobile communications, local network construction. In order to further speed up the technological transformation of the network, this year, the communications department will adopt wavelength division multiplexing (WDM) technology to increase the transmission speed of optical fiber trunks by eight times. In the past two years, China will expand its capacity by up to 30,000 km and 18 fiber optic cable trunk lines using 8X2.5Gbps wavelength division multiplexing technology. This year will be completed about 20,000 kilometers, 13 trunk cable technology transformation, will also focus on the completion of Xi’an - Hefei, Hohhot - Taiyuan - Nanning - Beihai, Lanzhou - Xining -
