当前,“宽带中国”已成业界热点。作为一个幅员辽阔、人口众多的大国,中国的宽带网提速并非易事。幅员辽阔,意味着宽带网升级的覆盖范围巨大;人口众多,意味着宽带网升级面对的是13亿人的信息通信需求。按照这个思路,如果光纤多一分损耗,乘以上千公里,则损耗巨大;而每一根用户线多花一点成本,就要乘以亿计的用户数,总量可观。因此,宽带网提速是一个综合技术进步、产业准备、经济核算、环境响应、政策支持等多方因素的系统工程。令人欣喜的是,与20年前中国通信产业无法跟上网络建设步伐的窘境相比,今天中国通信产业的能力已经足以
Currently, “Broadband China ” has become a hot industry. As a large and populous country, China’s broadband network is not easy to speed up. The vastness of the network means a huge coverage of broadband network upgrades. The large population means that the broadband network upgrade faces the information and communication needs of 1.3 billion people. In accordance with this idea, if the optical fiber more than a loss, multiplied by thousands of kilometers, the loss is huge; and each user line spend a little more cost, it is necessary to multiply the number of billions of users, the total considerable. Therefore, speed-up of broadband network is a systematic project that integrates technological progress, industry preparation, economic accounting, environmental response and policy support. It is gratifying that, compared with the dilemma of China’s telecommunications industry being unable to keep pace with the pace of network construction 20 years ago, the capacity of China’s telecommunications industry is sufficient today
