The OptiX OSN 3500 intelligent optical transmission system (the OptiX OSN 3500 for short) developed by Huawei is the next-generation intelligent optical transmission equipment. The OptiX OSN 3500 is of a universal switch architecture. That is, the OptiX OSN 3500 can be used in packet mode or in TDM mode. When used with the other equipment of Huawei, the OptiX OSN 3500 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.
