Test Certification Set Up in Torino for Production: the Goal The Device Under Test (DUT) are the CuOF boards We have to select the best components to tests the DUTs to be confident in the test set up Campaign of measurements of instruments we have: o Copper cables (2 blue cables, only 1 working) o VCSELS o Mother Boards Fan Outs o Trunk optical cables o OFCu o New PU The VCSELs, FanOuts,Trunk Cables come certified by industry, however we want to check their behavior within our application. 4/9/134CMSWeek 2013
