Abstract :
We describe a completely optically decoupled DAQ system, using a single optical fiber for feeding fast trigger and control signals to the front end electronics. Its main use is foreseen in the general environment of silicon microstrip detectors, with both single and double side readout. It has been shown to be very helpful, especially in case of double sided heavily irradiated silicon detectors where the bias operation voltage is around 500 V in order to get overdepletion and an optimal signal to noise ratio.
