This paper describes the principles and practical implementation of a novel form of optical fibre data telemetry system. The system modulates coherent light propagating in a multimode optical fibre by passing an ultrasonic wave across the fibre. The modulation process is highly efficient, and may be effected by simply attaching a suitable ultrasonic transducer to the outside of a fully cabled and protected fibre. Data connection does not interfere at all with the optical path through the system. A number of similar stations-up to perhaps fifty in total - may be connected to a single fibre link covering a distance up to several kilometres. The system is ideally suited for data collection functions from remote or hazardous areas, since the individual data input stations may be designed to consume minute amounts of power.
