Oversubscription Dimensioning of Next-Generation PONs with Different Service Levels


This letter provides a methodology for planning Passive Optical Networks using the oversubscription concept and shows its applicability in the dimensioning of 1 Gb/s access to both basic (i.e. residential) and premium (i.e. business) users with different service level requirements and activity patterns. We show that only Next-Generation PON networks can reach a large number of users with acceptable service levels.
