Abstract
A receiver for a burst Manchester encoded composite optical digital signal has an interferometer comprising two fiber optic transmission lines. The lines differ in length so that they have time delays that differ by the period of the sync signal. Thus, the interferometer extracts the sync signal from the composite signal. The sync signal and a data signal are detected by photodiodes.
