Optical digital pulse position modulation (DPPM) is an effective modulation format for both free space and fiber communications. However, for the latter, system synchronization has not been considered. Here, we address this issue and present an original expression, supported by practical results, for evaluating the frame spectral properties of optical fiber DPPM. We use the established properties to optimize frame synchronization while using a dispersed DPPM pulse shape which is representative of optical fiber systems © 1992 John Wiley & Sons, Inc.
