HUAWEI OptiX OSN3500 SDH

Brief Introduction

 

To meet the growing demands of Metropolitan Area Networks (MANs), Huawei has developed the OptiX OSN 3500—next-generation intelligent optical transmission system. Primarily used at the metropolitan convergence and backbone layer, the OptiX OSN 3500 incorporates an intelligent optical transmission platform and core optical transmission system to schedule and transmit services of different types and granularities. Leveraging "universal switch" architecture, the OptiX OSN 3500 can be used in packet or Time Division Multiplexing (TDM) mode. Combined with other Huawei equipment, the OptiX OSN 3500 supports various networking applications, such as pure packet mode, hybrid networking (packet and TDM mode overlay networking), and pure TDM mode. A proper networking solution can optimize both data and conventional Synchronous Digital Hierarchy (SDH) service processing.
