摘　　要：有线电视同轴电缆网络双向化采用低频段能够大大提高双向有效覆盖,通过定量分析双向低频段与跨接放大器级数之间的量化关系,阐述了提高双向有效覆盖的原理,并通过实例分析了本原理的应用。CATV coaxial network two-way changing with low frequency band can greatly improve the two-way effective coverage. In this paper, it describes the principle of improving the two-way effective coverage through quantitative analysis of the relationship between the two-way low frequency band and series of amplifiers. It describes the principle of improving the two-way effective coverage, and analyzes the application of this princi- ple through examples.
