Among the requirements of the PANDA Micro-Vertex-Detector (MVD) there are the capability to handle a high data rate with a continuous readout and a low material budget. These requirements, together with the layout constraints, demand dedicated low-mass cables for data transmission. Differential microstrips, realized with aluminum tracks laminated on a polyimide support, have been produced and experimentally tested for both electrical functionality and radiation hardness, using signal integrity techniques. Furthermore, the capability of the cables to cope with the SLVS signaling standard has been investigated. An overview of the results will be presented, examining the upper frequency limits of the samples and the dependences on layout and track width.
Finally, special focus will be given to the results of the radiation hardness measurements, performed with neutron irradiation at the research reactor at LENA (Pavia) and with proton irradiation at the cyclotron in Bonn.
