| description | The present invention relates to optical switching, and particularly to an apparatus and method for optical switch alignment.
In optical communication switching equipment there is a need to set up optical paths through the switch before there is an optical signal present. The present invention provides an optical switching apparatus comprising: an optical switch having a number of optical paths for switching optical channels; a demultiplexer coupled to said switch; a broadband light source coupled to said demultiplexer which distributes said light in said channels to enable correct alignment of said optical paths. |
