Abstract: HADES is a di-electron spectrometer operating at GSI, Germany. Currently, the HADES data and trigger system is being upgraded. The main aim is to substantially increase the event rate capabilities by a factor of up to 20 to reach 100 kHz in light systems and 20 kHz in heavy ion reactions. The data rate will be about 400 MByte/s in peak. In this context, the complete readout system has been exchanged to use optical communication. [ABSTRACT FROM PUBLISHER]
