Abstract

A bus system for the transfer of audio and control data on a common bus line of fiber optic cables (LWL) in a system of users is compatible with sources and sinks of audio data (2,2a,2b) and/or control and monitoring data (8,8a,8b). Each user is connected to the bus system by a standardized interface (6,6a,6b) circuited together in series via fiber optic cables (LWL A, LWL B) preferably closed to form a ring by means of a further fiber optic cable (LWL C). This bus system is suitable for being operated with an internationally standardized transfer format. The bus system is impervious to noise, can be produced at low cost and is exceptionally powerful. This bus system is particularly suitable for use in vehicles.
