Huawei OptiX OSN 7500/7500II MSTP

The OptiX OSN 7500 II intelligent optical switching system (the OptiX OSN 7500 II for short) is the next-generation intelligent optical core switching (OCS) equipment and is developed by Huawei on the basis of the current situation and development trend of the metropolitan area network (MAN).The OptiX OSN 7500 II is mainly used as a service scheduling node at the backbone layer of the MAN. That is, it functions as optical core switching equipment (OCS). As an intelligent optical transmission platform and core optical transmission system, the OptiX OSN 7500 II is located at the metropolitan backbone layer to schedule and transmit services of different types and granularities. The OptiX OSN 7500 II is of a "universal switch" architecture. That is, the OptiX OSN 7500 II can be used in packet mode or in TDM mode. When used with the other equipment of Huawei, the OptiX OSN 7500 II supports various networking applications, such as the pure packet mode application, hybrid networking application (overlay networking of the packet mode and TDM mode), and pure TDM mode application. By using a proper networking solution, the data service and conventional SDH service can be processed in the optimal manner.
