Description
Huawei PTN 7900-12 Router is Huawei’s new generation of metro optical transmission equipment for packet transmission. It is mainly positioned at the convergence layer and core layer of the metro transmission network. It sets up a bearer network for mobile services and major customer dedicated line services with a forwarding capacity of up to 2.4 T.
Huawei PTN 7900-12 Router Product Overview
Huawei PTN 7900-12 Router is a new generation based on 400G platform, with metropolitan area packet transmission equipment with a large capacity above T level, large bandwidth above 100GE, business intelligence and support of SDN. It is mainly located at the core convergence layer and provincial/national backbone of the metro transmission network Network, set up a bearer network for mobile services and dedicated customer line services.
The PTN 7900 series products support 40GE / 100GE / 200GE super large ports, with business intelligent monitoring functions, visible traffic, assessable quality, and predictable capacity. The new SDN architecture is used to effectively support the long-term development and evolution of operator networks.

Huawei PTN 7900-12 Router Product Feature
- Superior equipment capabilities to support the long-term evolution of the bearer network
Large forwarding capacity, flexible channeling of core traffic
Support 40GE / 100GE / 200GE large ports, smooth to 400GE in the future
Strong L3VPN capability, supporting massive base station bearers
The industry’s first SDN-based PTN, which simplifies operation and maintenance, and the - the future direction of PTN development
Standardized App interface, users can program and customize according to their needs, and new services are more convenient to open
Separate control and forwarding, decouple business features and hardware, simplify operation and maintenance, and accelerate business innovation
Unified control and management of decentralized devices to better and faster network deployment and management - Supporting Ethernet channelization and network fragmentation to achieve multi-service convergence and management
Forwarding Fragmentation: Implementing service forwarding plane isolation based on channelization technology
Management sharding: provide a proprietary view, independent management interface based on different services
Control sharding: In the future, SLA (delay/bandwidth, etc.)-Based services will be established on-demand and adjusted in real-time
