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.
