Performance Analysis and Evaluation of VDSL2 Systems: Band-Plan Study

— In this paper we discuss the performance of different profiles of VDSL2 systems in a frequency range up to 12 MHz (bandplan 998 and 997, corresponding to the European region) using two different noise scenarios: VDSL2 Mix and VDSL2 only. The use of different power levels at the downstream is evaluated in these scenarios and it is found that there is no need to use maximum power. As operators are commonly interested to achieve higher data rates, we have selected profile 12a as the most suitable when dealing with frequencies up to 12MHz while consuming 4 times less power at the downstream than profile 8b and leading to similar performance in the scenarios herein described. The impact of using different cables has been evaluated for both the downstream and upstream direction. An analysis on boosted and non-boosted masks is also provided. A method to evaluate the upstream performance per band has been used in order to obtain the contribution of each upstream band versus the loop length...
