目前光纤到桌面(FTTD——FiberToTheDesktop)的概念已逐渐为人们所接受,并已经在一些工程中得到应用。随着光纤价格的下降,综合多媒体应用的网络接入需求的不断增大,使越来越多的用户得以采用FTTD的解决方案。FTTD是一种宽带接入方式,使网络直接连接到桌面,人们可以更方便、更快捷地获得Internet资源,来享受网络带给我们的无限信息。本期主题“光纤飞跃——便捷的资源信息共享通道”特别发布了本刊独家调查的光纤应用的专题报告,分析了在工程应用中单模、多模光纤的使用等情况;展示在工程应用中光纤连接器的使用;剖析选择光纤的主要因素以及影响光纤应用的主要原因。在调查报告之后,本刊专门对部分综合布线厂商和系统集成商对FTTD的市场变化、影响FTTD发展速度的原因以及FTTD的应用前景等看法进行了访谈。
The current concept of Fiber To The Desktop (FTTD - FiberToTheDesktop) has become increasingly accepted and has been used in some projects. With the drop in the price of optical fibers, the increasing demand for network access for integrated multimedia applications has enabled more and more users to adopt FTTD solutions. FTTD is a broadband access method that allows the network to connect directly to the desktop, making it easier for people to access Internet resources more quickly and enjoy the unlimited information that the Internet brings to us. The theme of this issue of “Fiber Leap - A Convenient Resource Information Sharing Channel” has released a special report on the fiber optic applications exclusively investigated by this issue and analyzed the use of single-mode and multi-mode optical fibers in engineering applications. The use of fiber optic connectors; analysis of the main factors that affect the selection of optical fibers and the main reasons for the application of optical fibers. After the survey report, we specifically interviewed some integrated wiring manufacturers and system integrators on the market changes of FTTD, the reasons for the impact of the development speed of FTTD and the application prospect of FTTD.
