Abstract

This paper presents the crosstalk measurement result of 50 twisted pairs for fully filled type of copper cable bundle with different length i.e. 100 meters, 200 meters and 300 meters. This cable is being used by Telekom Malaysia (TM) to provide DSL technology in Malaysia. The frequencies range in this measurement was from 0.1MHz until 30MHz and this range was selected in order to model this measurement in VDSL2 environment. The result of this measurement was analyzed after scattering parameters was extracted by using Agilent Technologies Network Analyzer model E5071C. The outcome of this experiment is the relationship between the crosstalk and the length of the twisted pair inside a copper bundle. The result shows that crosstalk transfer function remains the same as the length of the cable increases and it represents TM copper cable better compared to ETSI model. The crosstalk transfer function generated from the analysis can be used to estimate bitrate performance according to the length of copper pair.

50双绞线TM铜缆上VDSL2技术的ext和NEXT分析

本文介绍了长度为100米、200米和300米的全填充型铜电缆束50对双绞线的串扰测量结果。这条电缆被马来西亚电信(TM)用于在马来西亚提供DSL技术。该测量中的频率范围为0.1MHz至30MHz，选择该范围是为了在VDSL2环境中对该测量进行建模。使用Agilent Technologies E5071C型网络分析仪提取散射参数后，对该测量结果进行分析。该实验的结果是串扰与铜束内双绞线长度之间的关系。结果表明，随着电缆长度的增加，串扰传递函数保持不变，与ETSI模型相比，它更能代表TM铜电缆。通过分析得到的串扰传递函数可以根据铜对的长度来估计比特率性能。
