Abstract: A controlling method for mitigating a rogue behavior of an Optical Network Unit (ONU) having a wavelength-tunable function in a hybrid Passive Optical Network (PON) system. The controlling method includes determining whether a first wavelength for an upstream signal received from the ONU strays away from an allowable range for a second wavelength assigned to the ONU, and, in response to a determination that the first wavelength strays away from the allowable range for the second wavelength, transmitting an upstream wavelength adjustment request message to the ONU to adjust a wavelength for the upstream signal. At this point, a determination on whether the first wavelength strays away from the allowable range for the second wavelength is made by calculating wavelength drift of the first wavelength and determining whether the calculated wavelength drift is greater than a drift threshold.
