桥接抽头 meaning in English
bridge tap
Examples
- Although adsl comes with new digital processing , coding , modulation and error correction technologies , it is also faced with various challenges out of subscriber lines , such as background noise , impulse noise , insertion loss , cross talk , wire size variations , bridge tap , line joints and line insulation , etc . all those factors tend to produce adverse impacts on the performance of high - speed transmission services . firstly , the insertion loss of copper lines increases in proportion to the length of lines
虽然adsl采用先进的数字信号处理技术、编码调制技术和纠错技术，但是在推广adsl业务时，用户线路的许多特性，包括线路上的背景噪声、脉冲噪声、线路的插入损耗、线路间的串扰、线径的变化、线路的桥接抽头、线路接头和线路绝缘等因素将影响高速率传输业务的性能。 - For recent years , adsl has world widely employed and widely used in many aspects such as vod , remote medical treatment and e - shopping etc . but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals , and the adsl ' s frequency rang is from 0 to 1 . 104mhz , so we must confront the signal attenuation , the loop line noise impairments , the crosstalk interferences , the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
近几年来， adsl在世界范围内得到充分的使用，广泛应用于视频点播、远程医疗、网上购物等各个方面。但是由于电话线网络是专门为传输低频信号而设计，而adsl的频谱范围在0 1 . 104mhz内，因此在传输adsl信号时，面临着信号衰减、线路噪声、串音干扰、桥接抽头反射和射频干扰等等多方面的问题，这就要求在adsl开通之前对线路进行一系列的测试。 - In particular , the bridge tap at the receiving side will make some sub - channels unusable . to that end , bridge taps on adsl lines must be examined and removed as much as possible . most importantly , there should be no bridge tap of any form at the receiving side
第四，线路的桥接抽头将显著地改变线路插入损耗的频响特性和相频特性，特别是接收端附近的桥接抽头将导致某些子信道无法使用，所以在使用adsl时，一定要检测线路上的桥接抽头，并尽可能地去除桥接抽头。
