ADSL( Asymmetrical Digital Subscriber Line or Loop )稱為非對稱
式數位用戶線(或稱迴路線),乃當今對銅線電纜傳輸技術上最重大的一項改革和突破,此傳輸方式不同於典型的同步或非同步方式來傳送語音和數據信號,為當今寬頻傳輸上一大利器。
近年來,網路發展快速,逐漸朝寬頻的方向前進,相對的網路品質要求甚高。本研究之目的,在於適時地選擇脈波反射儀器和橋式儀器,來檢視與分析銅網路各種不同的障礙波形和迴路漏電阻,將量測的誤差減至最低,迅速排除網路的障礙,為提升網路使用的品質,來盡一份心力。
ADSL is called Asymmetrical Digital Subscriber Line or Loop. It is the most momentous innovation and breakthrough of the transmission technique of copper cable nowadays. This kind of transmission is different from the typical synchronous or asynchronous way to transmit speech and data signals. Now it has a very convenient way for broadband transmission.
The internet has developed rapidly in recent years and gradually proceeds toward the goal of broadband. As a result, the demand for the quality of internet is very high. This research is to adequately select pulse echo instrument and bridge rectifier to examine and analyze various obstacle waves of copper internet and circuit leakage resistor. So it can minimize the error of measurement to the lowest and exclude the obstacle of internet and promote the quality of internet.
