This case study considers the rationale for KPN’s move to deploy XGS-PON and the results that have been achieved. It considers how the XGS-PON rollout provides the means for the operator to support higher-speed gigabit and multigigabit packages that will meet regulatory requirements on actual speeds delivered and that will also be robust in the face of growing traffic levels. The case study examines how the ability of XGS-PON to reliably offer gigabit upstream speeds is an important differentiator for KPN versus its cable competitors.
