OptiX PTN 7900 Transmission Systems

Huge-capacity Packet Transport Network (PTN) transmission engine with Software-Defined Networking (SDN) architecture for simplified O&M and smooth migration to fully virtualized networking, LTE, and a variety of value-added services.

Working at the PTN core layer, Huawei’s OptiX PTN 7900 supports 40 GE/100 GE interfaces — or replace with a 400 GE board — with forwarding capacity up to 3.84 Tbit/s. 

Energy-efficient electronics, dynamic power management based on the system’s configuration and operations, and intelligent heat dissipation features conserve power and reduce CO2 emissions by up to 40 tons annually over traditional PTNs.

Future-proof your next-generation core network with Huawei’s super high-performance, SDN-ready, OptiX PTN 7900 Packet Transmission Systems

  • Standard application interfaces allow for user-defined programming for rapid provisioning of new services
  • SDN architecture separates control and forwarding planes for decoupling of management services and simplified O&M
  • Huge processing and forwarding capabilities support resilient scheduling and performance at the core layer
  • Carrier-grade reliability performance optimizes uptime availability and protects core network assets
  • SDN design simplifies provisioning, management, and expansion
