DSL Advances

11.6. Predictions for the DSL Age

The possibilities for DSL are seemingly unlimited when augmented by dynamic spectrum management. Results in this chapter have shown that 100 Mbps symmetric transmission on 500 meters of cable is possible, are 100 Mbps at 800 meters, 50 Mbps at 1.5 km, and 25 Mbps in excess of 2 km. As fiber enters the loop plant and reduces loop lengths, DSM-charged DSL can enable 100 Mbps 100BT speeds to every customer in the future, and with less power and cost than existing DSL systems. The opportunity for the telecommunications industry is just unprecedented in terms of applications, service, equipment and chip revenue. A 500-meter binder of 50 pairs could carry 5 Gbps total capacity symmetrically and reliably, more than ...
