OptiX OSN550 optical terminal supports MPLS (MultiProtocol Label Switching) / MPLS-TP (MPLS-Transport Profile) / PWE3/ Ethernet/ ATM/ WDM/ SDH/ PDH technology, which can flexibly realize pure TDM mode, pure packet mode or Hybrid mixed-mode networking. OptiX OSN550 transmission equipment is mainly used in the access layer of the network to form an end-to-end network with Huawei OptiX OSN1500/ OSN2500/ OSN3500 series equipment, providing a complete solution from backbone layer, aggregation layer to access layer, meeting the application needs of 2G/ 3G/ LTE base station backhaul and private line access of major customers.

Large capacity, high availability, low energy consumption, compact structure.

As the access layer equipment of OSN series products, OptiX OSN550 has the characteristics of large capacity, high availability, low energy consumption, compact structure, and so on.

Maximum 64Gbit/s packet switching capacity and maximum 20Gbit/s SDH crossover capacity, up to four 10GE interfaces can be accessed at the same time.

Support master, crossover, clock, power unit 1x 1 device-level protection, support E1/T1 TPS protection. Support Tunnel APS, PW APS, MSTP, ERPS, LAG, LPT, ML-PPP, LMSP, MRPS, SNCP, multiplex section, and other network-level protection to improve the reliability of the equipment.

Maximum power consumption 300W Magi Hybrid typical power consumption is only 175.5W Magi TDM typical power consumption is only 107.3W.

The structure is compact, the integration is high, and the size is only 442mm (width) × 220mm (depth) × 88mm (height).

“Unified switching” architecture, giving consideration to multiple services.
Huawei OSN550 equipment is based on the “unified switching” architecture. It supports the service bearer mode of the coexistence of traditional TDM and packet dual domains, satisfies the on-demand configuration and application of pure TDM services and packet services, and can realize the smooth evolution from TDM domain to packet domain.

Huawei OSN550 equipment supports the access and transmission of PDH/SDH/ATM/Ethernet/MPLS/MPLS-TP services to meet multi-service applications.

Huawei OSN550 equipment adopts packet transmission technology to achieve efficient statistical multiplexing of data services, effectively reduce the transmission cost of each bit service; at the same time, inherit the advantages of SDH, provide Native bearer of TDM services, and effectively ensure the high quality of voice service transmission.

End-to-end service configuration/ one-button debugging / one-button fault location (TP-Assist).
Compared with the traditional TDM network, the operation and maintenance of packet network have the following characteristics:

The packet network does not have the perfect overhead bytes of the TDM network to indicate the physical state of the network. When the network fails, there is a lack of intuitive and fast fault location indication information.

The diversity and technical complexity of networking put forward higher requirements for the ability of operation and maintenance.

In order to solve the above problems of the packet network, the OSN550 equipment strengthens the operation and maintenance means and simplifies the operation and maintenance in the aspects of installation and adjustment, service configuration, fault location, and routine maintenance by supporting the TP assistant (TP-Assist), so that the packet network has the operation and maintenance capability similar to that of SDH, reduces the skill requirements for operation and maintenance personnel, and improves the operation and maintenance efficiency.

Networking scheme.
When there are a large number of Ethernet services and a small number of E1 services, the pure packet networking scheme is adopted to give full play to the advantages of PTN technology for large-flow and low-cost transmission, meet the needs of the multi-service operation, and improve the performance-to-price ratio of network construction and maintenance.

The FE/GE service of large particles is transmitted through the PTN network in pure packet mode, which can greatly reduce the transmission cost per bit.

Small particle E1 service is transmitted through the PTN network in TDM/ATM PWE3 mode, which can meet the demand of E1 service without the TDM network.
