Impact of Cable Bleeding into RLCG of Twisted Pair Copper Cable and Achievable Bit Rate

摘要

This paper we are actually investigating the impact of cable bleeding into RLCG twisted pair and achievable bit rate based on VDSL2 profiles (17a). The study has been done by carried out investigation on attenuation copper cable itself in ideal conditions and cable bleeding. S-parameter for ideal conditions with distances in 100m, 200m and 300m is obtained. Besides that, the copper cable 200m has been tested in non-ideal conditions when it is bleeding conditions defined by 0. 3cm lengths of bleed. It is observed that at 18MHz the attenuation is increases while the increases of cable distance. Then, from S- parameter results it can been analyzed into RLCG model which is can represents into lumped-element circuit and also the performances maximum achievable bit rate. It is found significant effect on the cable bleeding for 200m with it performances in attenuation and achievable bit rate compared to ideal conditions.
