METHODS AND APPARATUS FOR USING AN EMBEDDED OPTICAL SIGNAL SOURCE WITHIN AN OPTICAL NODE TO LOCATE PROBLEMATIC OPTICAL SPANS

摘要

Example embodiments and methods of the present invention relate to utilizing optical transmitters and optical receivers embedded within reconfigurable optical add-drop multiplexers of optical nodes to identify problematic optical spans within an optical network.

主权项

1. A method of identifying problematic optical spans, comprising:
identifying optical paths between network nodes; testing identified optical paths between network nodes; identifying degraded optical paths between network nodes based upon testing; counting occurrences of each optical span within the degraded optical paths between network nodes to create a total for each optical span; and comparing optical spans using the total for each optical span.
