Synchronization in modern optical systems is of paramount importance. The sharing of a common time between different network components constitutes a crucial factor towards system stability. Latest advancements in optical access networks, such as Passive Optical Networks (PONs), allow transmission rates of 10 Gbps. Hence, a very accurate synchronization method is required in order to keep the network free of blocking and collisions. In this work, we focus on 10-gigabit-capable passive optical network (XG-PON) systems, one of the most popular standards for PONs. A rigorous analytic approach is devised so as to investigate the required precision of underlying synchronization method. Closed equations for computing the no blocking and blocking probabilities are developed. The devised analytic framework is verified using simulation methods.
