Samenvatting

PON networks are designed around a minimum received power level. The actual use of power budgets in a PON typically varies widely. Utilizing multilevel modulation for ONUs that have high power margins can increase network capacity utilization without investing in expensive optics. In this paper we present statistics from a commercial GPON network and demonstrate that a capacity increase is possible for a majority of the users. Even users with a low power margin can benefit from multilevel modulation, if smart distribution of timeslots among users is utilized.
