The Future of DSL

For telephone companies to remain competitive in the telecommunications industry, they must innovate and seek new revenue streams from new technology. Upgrading of the old PSTN infrastructure is going on right now. It will take many years to upgrade the majority of the current copper cable capacity to fiber- optic cabling. Yet the higher bandwidth offered by fiber-optic cables will enable telcos to provide a wider range of services.

DSL is likely to remain a driving force for Internet connections for some time to come. Because it maximizes the otherwise - wasted frequency range of ordinary copper cables, DSL is a technology that can adapt to the current cabling of the PSTN, although it can provide that service only to a qualifying set of customers. As the fiber network grows farther out into the neighborhoods, you can expect to find that DSL technologies will become more widely available. As older copper segments of the PSTN are removed, so are obstacles that cause errors in DSL communications.

And with the improvement of the physical infrastructure of the PSTN, you should expect to see improvements and new types of xDSL technologies in the near future.
