The CMS Tracker will install over 40000 optical links in its data-readout and control system, representing an unprecedented deployment of this technology in a Particle Physics Experiment. After reviewing the Quality Process employed in this project, a summary of the performance data measured during production will be shown. The analysis of this data will then be used to illustrate how the performance of the installed system may be predicted, giving confidence that the specified functionality will be attained in the final system. Completion of the production has allowed reflection upon the processes used and improvements for future such projects will be given in the form of some lessons learned
