SDH传输设备_OptiX PTN3900 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40GE大带宽业务汇聚，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。

SDH Transmission Equipment_PTN 3900-8/3900: Supports 40GE ports to meet the demand for large-bandwidth aggregation, distributed architecture, separation of control and forwarding, and 1+1 redundant protection for master, cross, and power supply to meet the demand for high-reliability and large-capacity aggregation.

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.

SDH transmission equipment_OptiX PTN3900 is mainly located in the core layer of metro transport networks, supporting CES services, ATM services, Ethernet services, IP over PW services, L3VPN services, and up to 40GE services. With the functions of full media access, full media synchronization and full media management, PTN3900 can work together with other PTN products to set up 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.
