Abstract
Official abstract text for this publication.
A device for inserting/extracting at least one optical subband into an optical channel consisting of a plurality of optical subbands. The device includes an extraction means that is capable of extracting a first optical subband belonging to the optical channel, a suppression means that is arranged so as to obtain a filtered optical channel from the optical channel wherein at least one second subband is suppressed, and a coupling means that is capable of inserting a replacement optical subband in place of the second subband in the filtered optical channel so as to obtain a modified optical channel. The device moreover relates to an optical insertion/extraction switcher, using one or more insertion/extraction devices, and to the corresponding insertion/extraction methods.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for inserting/extracting at least one optical subband into/from an optical channel composed of a plurality of multiplexed optical subbands that are orthogonally frequency-multiplexed, the device comprising: a duplication means able to duplicate the optical channel to a first duplication port and a second duplication port: extraction means able to extract a first multiplexed optical subband belonging to the optical channel, consisting of band…
