人类自从触摸了网络,社会便以前所未有的速率向前发展,在改变物质与精神生活的同时,带动了全球新经济的商业进步,而这些进步又反作用于网络,将作为核心动力的网络技术推入新的革命,即光的革命。 最早提出光革命的当属北电网络,它认为目前运营商建网的一大趋势是对大容量日益膨胀的需求。所谓大容量法则是指在保持较高可靠性的前提下,将比特/公里的传输成本降低到最小,竞争力提高至最大。在全球市场竞争极其激烈的运作环境下,运营商需要采用经 Since human beings have touched the Internet, society has been moving forward at an unprecedented rate. While changing the material and spiritual life, it has led to the commercial progress of the new global economy, which in turn has repercussions on the Internet and has pushed the core technology of network technology Into a new revolution, the light of revolution. Originally proposed optical revolution was Nortel Networks, it believes that the current trend of a large number of operators to build a network is the growing demand for large-capacity. The so-called large-capacity law is to maintain the high reliability of the premise, the bit / km transmission costs to a minimum, the competitiveness of the maximum. Operators need to adopt the operating environment in the extremely competitive global market
