PTN 7900

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.
