  1. Bad Fibers LIU Qian

  2. 5.6 m Today we put the bundle 2 (West bundle) into the protecting tube. barrel Common end 9.4 m 9 m Put into sliced tube Put into coiled tube

  3. Then we used LED source and test fibers (bundle 45), and checked one by one. We found that 62-e, 62-f, 66-a have no light coming out from common end. LED source Test fibers barrel Watch from common end

  4. According to the database, 62-c, 62-e, 62-f, and 66-a have no data. For 66-a, we know it is broken, and we didn’t install it. For bundle 62. Since 62-c, 62-d, 62-e, 62-f are all bad, Fred suggested us using bundle 46 instead of it. So 46-c, 46-d, 46-e, 46-f are all installed. But maybe 62-e, 62-f are OK, it is the main bundle of these two fibers are broken. or

  5. According to the installation database, in this section, we have 60-h, 61-h as spare fibers. If we want to fix it, we’d better do it ASAP. The MDC group are installing their cables of west side. We use bundle 46 instead of bundle 62, and all of them are installed.

  6. For east side, I’ve checked the database, we won’t have this problem. Thanks! LIU Qian
