Summary:
When two wavelengths are used for PON ONUs, upstream bandwidth utilization can be made very efficient. If wavelengths are not evenly distributed, however, fairness among ONUs is violated. To deal with this problem, a fairness algorithm is suggested. Wavelengths asymmetry can be introduced on purpose to provide different priorities among ONUs. Algorithms and simulation results are presented for both cases.
