Abstract

About 2800 lines out of a total of 8,500,000 subscriber lines in Taiwan have been sampled and characterized. Various kinds of physical compositions and transmission characteristics were investigated and measured. It was found that the near-end crosstalk (NEXT) loss of Taiwan´s subscriber loops is about 10 dB worse than that of US local loops. A corresponding new foam-skin PIC cable is proposed to reduce the NEXT loss. The new type of cable will be used to replace the paper cable and old foam-skin PIC cable step-by-step. Based on the measured data, the feasibility of HDSL (high bit rate digital subscriber line) service in Taiwan is studied. To improve the HDSL service distance via the existing subscriber lines, several cable models are discussed and suggested
