Abstract
The invention relates to a method of operating a primary optical node, particularly an optical line terminal (OLT), for an optical communications system, wherein said OLT is configured to receive at least one upstream optical signal (uos) from at least one secondary optical node, particularly an optical networking unit (ONU), within at least a first wavelength range (wr), and to transmit at least one downstream optical signal (dos) to said at least one ONU within at least a second wavelength range (wr), wherein said OLT determines a currently unused wavelength subrange (wsr) within said first wavelength range (wr), assigns a specific target wavelength (λt) within said currently unused wavelength subrange (wsr) to said ONU, signals said target wavelength (λt) to said ONU, receives an upstream signal (us) from said ONU, and provides feedback information to said ONU.
