Research on application of IEEE1588v2 in optical transport network

With the development of 3G/LTE, the high precise time synchronization application used the IEEE1588v2 standard become a great demand in telecommunication. This paper firstly introduces the principle and architecture of IEEE1588v2 and the structure of Optical Transport Network (OTN). According the characters of OTN, The platform used the timing clock module is designed and analysis. Finally the practical test is made and the results show the time synchronization accuracies can reach nanosecond range.
