We present an overview of the CDF End Plug Upgrade Project. The structure of the upgraded calorimeter and the design of the optical readout system is discussed. We describe the production of scintillating tile/fiber multi-tile assemblies (megatiles) and present the quality control results of megatiles produced for the CDF End Plug Upgrade Hadron Calorimeter. The sample of megatiles presented in this analysis corresponds to approximately 16,500 individual tile/fiber assemblies. We discuss the quality control requirements and present the distributions of the quantities measured during the QC process. The various contributions to the tile-to-tile light yield variations are isolated and discussed.
