Abstract
Controller circuitry configured to control an optical transceiver of an optical line terminal, OLT, in a passive optical network, PON. The controller circuitry configured to derive a level of optical beat interference, OBI, of a received upstream optical signal from an optical transceiver of an optical network terminal, ONT; and set a wavelength of a downstream optical signal based on the level of OBI such that the wavelength is forced to differ from the upstream optical signal wavelength.
