Abstract

The present invention relates to a solution for handling large dynamical signals in a passive optical network system and in particular for determining scheduling of bursts from a plurality of optical network units This solution is provided as a method, devices, system and a computer program for determining a bit error ratio, i e BER in received communication data, determining, using the BER, optimized transmission scheduling of communication bursts from the optical network units, and providing a signal to the optical network units indicating the transmission scheduling of transmission bursts in accordance with the determined optimized transmission scheduling.
