However,  there are two more broken fiber at Cable A, SM1. Namely,</p> <div class='table-wrap'> <table class='confluenceTable'><tbody> <tr> <th class='confluenceTh'>#mod</th> <th class='confluenceTh'>#cm2</th> <th class='confluenceTh'>#sp</th> <th class='confluenceTh'>#fh</th> <th class='confluenceTh'>#fid</th> </tr> <tr> <td class='confluenceTd'>4</td> <td class='confluenceTd'>2</td> <td class='confluenceTd'>1</td> <td class='confluenceTd'>3</td> <td class='confluenceTd'>3</td> </tr> <tr> <td class='confluenceTd'>12</td> <td class='confluenceTd'>21</td> <td class='confluenceTd'>1</td> <td class='confluenceTd'>114</td> <td class='confluenceTd'>114</td> </tr> </tbody></table> </div> <p>I think these two fibers should be marked as broken fibers too. (Note: strictly speaking, fid=3 is fiber with very low transmission, not completely broken.)</p> INSTRM-1729

Cobra .xml file is missing two broken fiber of SM1
