Abstract
An optical network unit for a passive optical network (), configured to: initiate an upstream wavelength (w) for an upstream signal (US) from the optical network unit to an optical line terminal (); iteratively, until an iteration criterion is met, i) transmit the upstream signal (US) to the optical line terminal (), ii) receive from the optical line terminal () power level data (p) for the upstream signal (US) as measured by the optical line terminal (), and iii) set the upstream wavelength (w) for the upstream signal (US) to a new wavelength-value; and adjust the upstream wavelength (w) to a wavelength-value previously set for the upstream signal (US) and associated with power level data corresponding to a certain power level. A passive optical network system, the optical line terminal and related methods are also disclosed.
