Sensor for a receiving device for cooperation with an optical fiber

摘要

Receiving device for cooperation with an optical fiber and comprising a sensor for converting a signal in the form of a modulated beam outputted by the optical fiber into an electric signal. The sensor comprises two or more mutually separated sensor elements. An output of each sensor element) is coupled to an amplifying element, which is coupled to an analog to digital converter associated with the amplifying element. The sensor elements and the amplifying elements connected thereto are provided on a single semiconductor chip. The analog to digital converters may also be provided on the semiconductor chip. The integrated circuits on the semi conductor chip are clock-controlled and a clock rate for the integrated circuits is lower than a clock rate corresponding to the bit transfer rate of the modulated beam. Means are present for reconstructing the signals in the beam from signals delivered by the sensor elements at the clock rate for the integrated circuits.
