As the degree of enterprise modernization increases and communication services develop rapidly, smart grids, rail transportation, broadcasting and television networks, digital oil fields, and other fields pose new challenges to transmission networks, and reliable and efficient communication networks have become an essential resource for enterprises to participate in international competition. Huawei is the first in the industry to release SPTN solutions, introducing a future-oriented packet transport network that supports multi-service converged bearer, high bandwidth, and differentiated quality assurance.

OptiX PTN 1900是面向分组传送的新一代多业务框式设备，主要定位于分组传送网的汇聚层，支持10GE带宽业务汇聚，环境适应性强，提供丰富的设备级、网络级保护，实现高可靠业务汇聚转发。

Huawei's PTN series of multi-service packet transport equipment has been commercialized on a large scale and serves more than 90 operators worldwide, lowering network construction TCO, saving bandwidth costs, and improving service deployment and network operation and maintenance efficiency.

OptiX PTN1900 is mainly located in the aggregation layer of transport network, supporting CES service, ATM service, Ethernet service, IP over PW service, L3VPN service, and up to 10GE service. OptiX PTN1900 has the features of full-media access, full-media co

With the functions of full-media access, full-media synchronization, full-media management, etc., it can be used with other PTN products to build an end-to-end packet transport network, which reduces TCO of network construction and improves the efficiency of service deployment and network operation and maintenance.
