随着3G时代通信业务的不断发展，传统的室内分布系统越来越难以满足人们的需求。为解决这一问题，介绍了一种新型的光纤分布式系统，从工作原理、特点和工程应用三个方面来分析该系统的优越性，设计旨在克服传统分布系统功率大，分布复杂，差损大等缺点，建设传输更方便，分布更合理的节能环保型系统环境。工程实际开通结果也表明，这种新型的分布式系统在解决信号覆盖及成本控制等方面更能满足现阶段人们的需求。%With the fast development of communication services in 3G era, traditional indoor distributed system is difficult to meet people’s communication requirements. This paper introduces a new type of fiber distributed system, according three aspects of its principles, characteristics and engineering applications to analyze the advantages of the system. The system not only can overcome traditional distributed systems’ disadvantages in high power, complex distribution and high differential loss, but also can build energy-efficient and environmental protecting systems with efficient transmission and reasonable distribution. The engineering practice shows that the new type of distributed system is suitable for signal coverage and cost control in this stage.
