<p>The invention describes a method for detecting starts of burst mode data packages, having burst clock domain data frequencies and time gaps in between two burst mode data packages, in an input data stream of an Optical Burst Mode Receiver comprising the steps of:
- transferring the optical signal of the input data stream into an electronic signal data stream by an O/E-conversion device (3), preferably wherein the amplitude of the electronic signal data stream is equalized by means of clipping,
- completing a permanent data stream by synchronizing the electronic signal data stream by recovering the input data rate corresponding to the burst clock domain data frequency of a particular burst mode data package and transferring the data rate of the electronic signal data stream into a data frequency of a local clock domain, and introducing stuffing bits into the time gaps in between the burst mode data packages of the electronic signal data stream by data stream completing means (7), wherein
after the completing of the permanent data stream a predefined bit string is searched in the permanent data stream and a start of one of the burst mode data packages is detected by recognising a digital pattern match of the predefined bit string in the permanent data stream by burst indication means (9).</p> |
