摘　　要：为了在光传送网(OTN)分组交换技术的解映射过程中尽量减少锁相环的使用问题,设计了一种基于同步时钟产生的均匀缺口时钟来实现解帧以及ODU2(光传输单元)解映射到ODU1(光数据单元)的同步电路。通过仿真验证了该同步电路功能的正确性。实验结果表明,该电路能够实时、准确地完成ODU2到ODU1的解映射。In order to solve the optical transport network(OTN)packet switching technology solutions for mapping process to minimize the use of phase-locked loop,a uniform gap is designed based on synchronous clock frame to implement the solution and ODU2(optical transmission unit)solution is mapped to a ODU1(light data unit)of synchronous circuit.The simulation results verify the accuracy of the synchronous circuit function.The experimental results show that the circuit can be real-time and accurate finish ODU2to ODU1solution mapping.
