Integration of the CMS Tracker Optical Links

The world’s largest point-to-point optical link system is being developed at CERN for readout and control of the CMS Tracker. The optical links are currently being integrated into the Tracker sub-detector systems and preparations are underway for final cabling and connection of the Tracker in CMS at LHC Point 5. Development was recently completed on the dense, in-line optical patch-panel in addition to the back-end patch-panel. Quality assurance and quality control procedures related to cabling and connections, acceptance tests, and tests of final system performance have been defined and practiced. The recent experience during sub-detector integration and the CMS Magnet Test Cosmic Challenge is described.
