This paper proposes a new dynamic wavelength allocation algorithm for TWDM PON (time and wavelength division multiplexed passive optical network) which comprises of multiple ONUs (optical network units) which have low-speed wavelength tuner. The wavelength tuner requires large amount of frame times to tune its wavelength. An OLT (optical line termination) performs a dynamic bandwidth allocation after the wavelengths of ONUs are determined.
