Περιγραφή

Huawei OSN7500 SDH is a new generation of core intelligent optical switching equipment developed by Huawei based on the current status and future development trends of the metropolitan area network. It is mainly applied to the business scheduling node of the metropolitan area network backbone layer, namely OCS (Optical Core Switching) equipment type.

Huawei OSN7500 SDH Product Overview

As an intelligent optical switching platform and core optical switching system,

Huawei OSN7500 SDH is positioned at the backbone layer of the metropolitan area network, and can complete multiple types and different granular business scheduling and transmission.

Huawei OSN7500 SDH adopts a unified switching architecture, which can be used as packet equipment and TDM equipment based on MPLS/MPLS-TP technology. With other Huawei equipment, OSN 7500 supports different networking applications: pure packet mode applications, υβριδικές εφαρμογές δικτύωσης (grouping mode and TDM mode overlay networking) and pure TDM mode applications to achieve the best processing of data services and traditional SDH services.

In the TDM mode, the OSN 7500 has a large service crossover capacity, with a maximum of 360Gbit/s high-order crossover and 40Gbit/s low-order crossover. In packet mode, its packet switching capacity can reach up to 160Gbit/s.
