摘要： The present document relates to optical transmission systems. In particular, the present document relates to a system and method enabling the coexistence of tunable and non-tunable Optical Network Units (ONUs) in a passive optical network (PON), e.g. a wavelength division multiplexing (WDM) PON. A media access controller for a passive optical network (200) is described. The passive optical network (200) comprises a first optical line terminal (201) with a receiver for a first wavelength range; a second optical line terminal (202) with a receiver for a second wavelength range, adjacent to the first wavelength range; and an optical network unit (101) with a transmitter having a transmitter wavelength which drifts between the first and the second wavelength range. The media access controller is adapted to assign the optical network unit (101) to the first (201) and the second (202) optical line terminal, such that an optical burst transmitted by the optical network unit (101) is received by the first optical line terminal (201) and the second optical line terminal (202).
