Course: Optical data buses for automotive applications (MOST bus)

Due to the ever-increasing multimedia networking and the data rates of the comfort systems, the MOST bus has established itself today as a standard for these applications. Especially for the display of high-resolution video content, the MOST bus has become indispensable.  Today's trainees will consequently encounter this topic frequently in their professional lives. The UniTrain system addresses physical basics and trains practical diagnosis. The training system represents a replica of a complete fibre-optic transmission system in a motor vehicle with display and attenuation measuring device. As well as an optical gauge for generating defined disturbances in optical fibres and for investigating coupling losses at splice points of an optical fibre transmission link.

Course contents:

  • Data networks in motor vehicles
