Text 3.1
The information industry: Embler of Economic Growth
信息产业:经济增长的引擎
In 1947,a device called the transistor was invented in Bell Laboratories, the research and development arm of AT&T (now Lucent Technologies). That invention helped to establish entire branches of industry, including consumer electronics, computing, and titans such as Sony and Microsoft. // Now, the changes taking place in our optical technologies are so significant that they have been compared with the development of the transistor. // Optical fibers form a network that interconnects the globe. These fibers are used to transmit our phone calls, faxes, TV programs, e-mail, data and many other types of information. //
1947年,美国电话电报公司(现在为朗讯科技)的研究开发机构贝尔实验室发明了被叫作―晶体管‖的一个电子装置。//
这项发明有助于整个分支产业的建立,包括家用电器和计算机行业,同时催生了诸如索尼和微软这样的电子巨头。而今光纤技术的蓬勃发展势头也丝毫不逊于晶体管。//
光纤构成的网络连接着整个世界。这些纤维被用来传输我们的电话、传真、电视节目、电子邮件、数据以及其他各式各样的信息。//
Until quite recently, it was possible to send only one wavelength (or color) of light along each fiber. A lot of effort is concentrated on maximizing the amount of information that can be transmitted using this single wavelength. // But dense-wavelength-division-multiplexing (or DWDM) makes it possible to transmit a large number of wavelengths on a single fiber, effectively sending a ?rainbow‘, where there was only one color before. // If we compare this with a crowded highway leading into a big city, for example, it‘s almost as though by installing just two boxes, one at each end of the highway, and adding a small amount of additional equipment along the route, we suddenly expand the highway to multiple levels, allowing the vehicles to choose from a large number of identical highways. //
