In SummaryHDSL is an innovation that bridges the gap between copper cables and fiber optics, via a process that PairGain Technologies calls CopperOptics. Essentially, it leverages the huge investment in copper cable plants worldwide, by enabling pristine signal transmission over existing copper cable at speeds of up to 2 mbps. Used for public network access and in private campus area networks, HDSL employs sophisticated electronics at either end of the copper cable to elegantly send information over copper wire. By using existing cable and inexpensive electronics, HDSL can be implemented quickly and without the excessive labor charges required to run fiber optic cable or implement repeatered T1/E1. With the abundance of copper cable throughout the world the application of HDSL is virtually limitless. |
