Huawei OptiX OSN550  optical transmission SDH system

Product Positioning

This section describes product positioning and networking application.

The OptiX OSN 550 is a packet- and TDM-oriented new-generation multi-service CPE optical transmission system, which is positioned at the access layer among Huawei's end-to-end Hybrid multi-service transmission platform (MSTP) product series. This system is characterized by its large capacity, high availability, low power consumption, and compact structure.

The OptiX OSN 550 supports multiprotocol label switching (MPLS), MPLS-transport profile (MPLS-TP), pseudo wire emulation edge-to-edge (PWE3), Ethernet, ATM, WDM, SDH, and PDH technologies. With these technologies, a pure TDM network, pure PTN network, or Hybrid network can be provisioned.

As the access layer equipment, the OptiX OSN 550 is networked with other OptiX OSN equipment to provide a complete solution covering the backbone layer, aggregation layer, and access layer. The complete solution meets 2G/3G/LTE base station backhaul and enterprise leased service access demands. Figure 1 illustrates the network application of the OptiX OSN 550.
