Huawei OSN3500 Introduction

Positioning

Huawei OptiX OSN 3500 intelligent optical transmission system (the OptiX OSN 3500 for short) developed by Huawei is the next-generation intelligent optical transmission equipment.

Huawei 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.

Technology

The OptiX OSN 3500 transmits voice and data services on the same platform with high efficiency. It integrates the following technologies:

• In packet mode, the OptiX OSN 3500 supports the following technologies:
  • Multiprotocol Label Switching (MPLS)
  • Multiprotocol Label Switching Transport Profile (MPLS-TP)
  • Pseudo Wire Edge to Edge Emulation (ETH PWE3)
  • TDM PWE3
  • ATM PWE3
• In TDM mode, the OptiX OSN 3500 supports the following technologies:
  • Synchronous digital hierarchy (SDH)
  • Plesiochronous digital hierarchy (PDH)
  • Ethernet
  • Asynchronous transfer mode (ATM)
  • Storage area network (SAN)/Video
  • Wavelength division multiplexing (WDM)
  • Digital data network (DDN)
  • Pulse Code Modulation (PCM)

Network Application

As shown in Figure, the OptiX OSN 3500 is mainly used at the convergence layer and backbone layer of the metropolitan area network (MAN). The network application scenarios are described as follows:

• In TDM networking, can be networked with the other OptiX transmission equipment (the OptiX OSN 9560, OptiX OSN 9500, OptiX OSN 7500 II, OptiX OSN 7500, OptiX OSN 3500 II, OptiX OSN 2500, OptiX OSN 1500, OptiX OSN 500, and OptiX OSN 550) to optimize the carrier's investment.
• With the packet switching technology, can constitute a packet data transmission network with the other OptiX transmission equipment (the OptiX OSN 7500 II, OptiX OSN 7500, OptiX OSN 1500, OptiX OSN 500, OptiX OSN 550, OptiX PTN 910, OptiX PTN 950, OptiX PTN 1900, OptiX PTN 3900, and OptiX RTN 900) to meet the requirement for bearing IP services.
• Can be flexibly networked with WDM equipment and Huawei Metro equipment.
• Can transparently transmit services over third-party Layer 2 networks, allowing end-to-end configuration and management.
