OSN 580 is a new-generation optical transmission system developed by Huawei. It adopts a unified switching architecture and can function as an MPLS/MPLS-TP-based packet device or a TDM device. When working with other devices of Huawei, OSN 580 supports various networking modes, including the pure packet mode, hybrid networking (packet + TDM) mode, and pure TDM mode, achieving optimal processing for packet services and traditional SDH services. Thus, OSN 580 efficiently transmits voice and data services over the same platform.
In TDM mode, OSN 580 supports 280 Gbit/s higher order cross-connect capacity and 20 Gbit/s lower order cross-connect capacity. In packet mode, OSN 580 supports 280 Gbit/s packet switching capacity.
OptiX OSN series products use a unified switching architecture, which can meet the requirements of conventional services and mushrooming packet services.
OSN 580 supports unified transmission of 40 Gbit/s packet and TDM services at a maximum distance of 80 km without optical amplifiers or dispersion compensation. The channel bandwidth can be flexibly adjusted based on the bandwidth of packet and TDM services, reducing the deployment costs of MANs.
OSN 580 provides a comprehensive solution for 3G/LTE mobile backhaul based on its packet domain to achieve scheduling of wireless services at the aggregation layer.
OSN 580 uses the built-in WDM technology to transmit several wavelengths over an optical fiber. This feature allows OSN 580 to interconnect with WDM equipment to achieve flexible networking.
The TP-assist implements care-free maintenance solutions for packet transport networks (PTNs) based on the MPLS/MPLS-TP architecture. The OSN 580 provides a planning tool for PTNs, which enables end-to-end visible service configuration of media gateways and instrument-free site deployment. Moreover, the OSN 580 supports automatic fault locating and performance monitoring of packet services.
