The PANDA experiment at the upcoming FAIR accelerator facility will study antiproton annihilation reactions at antiproton beam momenta from 1.5 GeV/c up to 15 GeV/c. The PANDA homogeneous electromagnetic calorimeter has been designed to meet the physics goals of the PANDA experiment. The calorimeter consists of lead tungstate (PbWO4 ) crystals and ensures an efficient photon/electron detection in a wide range of energy with a high resolution. In order to achieve the required energy resolution of the electromagnetic calorimeter, the individual crystal channels have to be calibrated and their radiation damage must be monitored and recovered. An optical fiber distribution system has been developed for the backward end-cap of the PANDA electromagnetic calorimeter. The optical prototype system provides light uniformity better than 95% which enable us to precisely calibrate the crystals. In this contribution, a description of the technical design and the performance of this prototype is presented.
