随着全球信息化的发展，电缆的应用场合已经渗透到社会的各个行业。针对基于FSK的电缆分线方法无法解决脉冲宽度和测量时间的矛盾，且只适用于短距离的传输等缺点提出了一种基于OFDM的电缆分线测试方法，仿真实验和测试结果表明该方法能有效克服了电缆信道存在的码间干扰，频率选择性衰减等问题。在提高数据传输速率的同时，有效地解决了电缆通信的问题。

With the development of global information technology,applications of the cable has permeated all sectors of society. The FSK-based cable distribution method does not resolve the contradictions q pulse width and measure-ment time and it applies only to the short distance.A cable distribution OFDM-based testing methods was proposed. The simulation and test results show that the method can effectively overcome drawbacks of the inter-symbol exisitng in cable channels,frequency selective fading and other issues,increase the data transfer rate,and solve the problem of cable communications.
