TWDM PON (time and wavelength division multiplexed passive optical network) uses multiple wavelengths to transmit packets upstream and downstream. In upstream transmission, if we use only one wavelength, the unused bandwidth is equally distributed to each ONU (optical network unit). In contrast, when multiple wavelengths are used, the unused remainders of wavelengths are different from each other. Therefore, it is difficult to fairly allocate the unused bandwidth to each ONU. This paper proposes a new method to allocate the unused bandwidth to each ONU in TWDM PON which uses multiple wavelengths.
