有线宽带接入方式FTTx与DSL比较与分析

Comparision and analyzation of wired accessing FTTx and DSL

DSL传输速率越高，其传输距离将会缩短。光纤可以适应高速远距离传输信号。目前有线传输进入了光进铜退阶段，FTTx＋ADSL2＋／VDSL2有线宽带接入方式将是主流。

Clearly, a higher DSL rate requires to shorten its transmission distance. And fiber optic is easy to carry signals from long distance. Therefore wired acc, essing evolves into the time of copper back into the light, FTTx ＋ ADSL2 ＋/VDSL2 becomes the main wired accessing method.
