| Mobile technology from 2G to 3G, LTE development to promote the mobile carrier networks from traditional TDM technology toward a higher bandwidth, lower cost, more flexible packet technology evolution. PON as a new transmission technology, packet-based architecture, drawing on a comprehensive SDH protection switching, rich OAM, for operators to manage the construction, operation and maintenance of unity can be the integration of transport network solutions provide a good idea.Work of switching mobile network base stations, roaming and so requires precise timing control to avoid the user to switch between base stations during the off-line, a phenomenon affecting other users. This article describes the passive optical network for accurate time synchronization with the 1588V2 implementations, elaborated on passive optical network (PON) on the time synchronization solution for time synchronization accuracy, reliability, compensation, etc. Key technical points were analyzed.Implemented in accordance with this prototype in the UAE Telecom, Deutsche Telecom, British Telecom has been demonstrated and tested. From the test results, the base station carrying this program works well, etc., can fully meet the technical requirements, and works with can be implemented. Clock synchronization technology used in PON, PON load for the whole business, then as a full-service access technology to provide the necessary foundation. |
