Abstract

This article addresses the problem of achieving high-precision time synchronization in optical transport networks for next-generation 5G/6G systems. The paper analyzes existing synchronization methods including PTP (Precision Time Protocol) and SyncE (Synchronous Ethernet), identifies their limitations under dynamic network conditions, and proposes an adaptive delay compensation algorithm. MATLAB simulation results demonstrate that the proposed approach reduces synchronization error by up to 40% compared to conventional PTP methods, achieving accuracy within ±50 ns for real 5G/6G transport networks.
