ADD-DROP DEVICE AND CROSS-CONNECT DEVICE FOR WAVELENGTH MULTIPLEX SIGNALS |
摘要 |
<p>According to the invention, in add-drop devices of an optical cross-connect device for wavelength multiplex signals, tributary drop signals to be dropped are pre-selected in the drop branch by means of pre-selection elements. Only these signals are amplified, thus reducing the number and/or power of the optical amplifiers. The tributary drop signals are individually selected by means of drop routing elements and adjustable filters. The add branch is created correspondingly.</p> |
