| 摘要 |
<p>The invention relates to a method of operating a primary optical node (100), particularly an OLT, for an optical communications system (1000), wherein said OLT (100) is configured to receive at least one upstream optical signal (uos) from at least one secondary optical node (200), particularly ONU, within at least a first wavelength range (wr1), and to transmit at least one downstream optical signal (dos) to said at least one ONU (200) within at least a second wavelength range (wr2), wherein said OLT (100) determines (400) a currently unused wavelength subrange (wsr2) within said first wavelength range (wr1), assigns (410) a specific target wavelength (»t) within said currently unused wavelength subrange (wsr2) to said ONU (200), signals (420) said target wavelength (»t) to said ONU (200), receives (430) an upstream signal (us) from said ONU (200), and provides (440) feedback information to said ONU (200) .</p> |
