NO$\nu $A Far Detector Module Fiber QA Test Analyses

In an effort to better understand the fiber-optic technology used to read out information regarding neutrino interactions in the NOvA far detector, various tests are performed at multiple stages of the detector module production. These fiber tests are used to check for and find sources of damaged fibers that may yield faulty readings. Analyses were performed specifically on the Stringing Fiber Test, closed fiber test, and visual inspection test both with and without a card. Cross-analyses were also performed to consolidate the data from these various tests and draw conclusions regarding the location and source of damaged fiber. The goal is to minimize the number of future tests that need be performed on a module while maintaining a high confidence level in the acceptance and rejection of modules to be installed at the detector site.
