摘　　要：针对网络传输带宽的瓶颈限制，该文提出一种带宽改造方案，对现有网络进行改造，设计的依据是电话线传输上行链路信号，闭路电视传输下行链路信号。利用现有的网络既可以实现上网功能，又可保持原有电话线路和电视线路的功能，减少重新布线造成的资源浪费，对解决光纤入户的带宽瓶颈问题和今后的家庭智能化提供一种方式。该文改造方案可以增加带宽，提高传输速率。An scheme of bandwidth-improvement to improve the existing network for the bottleneck limitation of the net-work’s transmission bandwidth was presented here in the paper . It depends on a principle that telephone line transmit up-links signals and CATV transmit down-links signals . The use of the existing network can be realized basic functions of telephone and television at the same time, extra function of surfing the Internet . This design presented in the paper can effectively reduce the re-source wast and provide a good way to solve the bandwidth bottleneck in FTTB（Fiber To The Building） and intelligent home in the future . The scheme in the paper can effectively increase bandwidth and increase the transmit data bit rate.
