摘要：

An original model for timing jitter estimation in optical-fiber PPM is developed and used to examine the performance impairment due to imperfect slot synchronization. An original expression that predicts the spectral properties in the presence of jitter is presented. The extracted slot clock timing variance is evaluated in terms of the PPM parameters such as the number of slots and the modulation index, and the effects of the other parameters such as the phase-locked loop (PLL) bandwidth and the fiber bandwidth are examined and used to optimize the slot clock timing variance. Original results are presented for the system wrong slot error (WSE) probability due to imperfect synchronization. The results indicate that this probability can be maintained well below the 10(-9) system operating error rate. The model enables the identification of the set of optimum PPM, PLL, and fiber parameters for a given required performance. (C) 1994 John Wiley & Sons. Inc.
