为了实现跨越不同网络的无间断服务和随时随地的高速率数据接入,提出了采用光学方法产生超宽带信号的技术,该技术的采用避免了额外的电光或者光电转换,节省了系统资源,有益于全光网络的形成。基于国内外的诸多研究成果,首先对利用光学方法产生超宽带信号的技术方案进行了认知与分析,在此基础上,以元器件为分类标准归纳总结出三类在光领域中产生超宽带信号的方法;然后结合实例对超宽带信号进行了应用分析,证明了超宽带信号的实用性与优越性;最后指出了超宽带系统未来的发展趋势以及存在的问题。
In order to achieve uninterrupted service across different networks and high-speed data access whenever and wherever possible, an optical method for generating ultra-wideband signals is proposed. The adoption of the technology avoids extra electro-optical or optoelectronic conversion, saves system resources and is beneficial All-optical network formation. Based on many research results at home and abroad, firstly, the technical scheme of using optical methods to generate ultra-wideband signals is first recognized and analyzed. Based on the above, three categories of ultra-wideband Signal method. Then the application of UWB signal is analyzed with examples to prove the practicability and superiority of UWB signal. Finally, the future trends and existing problems of UWB system are pointed out.
