At the same length , the insertion loss of different sub - channels also undergoes changes . this effect , along with the intrinsic background noise , impulse noise and the receiving sensitivity of modem on the adsl , will limit the maximum transmission distance on one single subscriber line 首先,铜线的插入损耗将随着线路距离的增加而成比例地增加,并且在同一距离下各子信道的插入损耗也发生变化,这个因素和线路固有的背景噪声、脉冲噪声、调制解调器的接收灵敏度一起将限制在单用户线上adsl所能够传输的最大距离。
