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.
