Huawei SDH Optical Transmission Equipment_Optix OSN7500 Optical Transmitter Intelligent Optical Switching System is a new generation of 10G intelligent multi-service optical transmission platform that inherits all the features of MSTP technology, maintains compatibility with traditional SDH and MSTP networks, and integrates technologies such as SDH, PDH, Ethernet, WDM, ATM, ESCON, FC/FICON, DVB-ASI (Digital Video-Asynchronous Serial Interface), RPR, and so on. Broadcast-Asynchronous Serial Interface (DVB-ASI), RPR and other technologies into a new generation of 10G intelligent multi-service optical transmission platform (MSTP), mainly used in the backbone layer of the metropolitan network, for the existing SDH equipment to the transition of intelligent optical network equipment to provide a perfect solution. It is mainly applied in the backbone transmission network of highway communication system.

Product Features
Cost-effective Platform
OSN7500 Optical Converter/OSN3500/OSN2500/OSN1500 service boards and software are fully compatible and constitute a unified platform. This can greatly reduce maintenance costs and the cost of spare boards and spare parts. the OSN intelligent platform is efficiently combined in terms of service capabilities, giving operators the most cost-effective solution; at the same time, it can be mixed with Huawei's existing equipment for networking, and it can be incorporated into Huawei's optical network network management solution for unified management.
