摘　　要：21世纪,世界将被“信息高速公路”连接起来,而接入网的带宽已成为“信息高速公路”和用户之间连接的瓶颈.本文介绍了混合光纤同轴接入网技术的原理以及该技术在我国的应用,并讨论了目前存在的问题以及解决方案.The increasing requirements of information and sorts of services accelerate the development of the access network. The use of the optical fiber is the direction. But the high cost of the optical network and the present actuality determine that the HFC broadband access network based on the CATV network is the best scheme. The principle of HFC and the application in our country was introduced. At the end, the inherent limitation of present HFC was discussed and some solving plans were provided.
