基于XDSL 串扰噪声的应对技术分析研究

摘要

In the DSL environment,Because the cable internal line of unshielded and crosstalk caused by electromagnetic coupling,Crosstalk noise caused by XDSL rate decreased very repetitive training and effect of service quality.In this paper, analyses the causes of the crosstalk performance loss caused by the training and discusses the method to solve the stability problem of crosstalk.%在DSL运行环境中，由于电缆内部线对间的非屏蔽而存在电磁耦合导致的串扰。串扰噪声造成XDSL速率下降甚至重训练，影响业务质量。本文对串扰导致的性能损失和导致重训练的原因进行分析并且就解决串扰导致稳定性问题的方法进行探讨。
