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.

Optix PTN7900

OptiX PTN 7900 NE is the new generation high-capacity, high-bandwidth, and software-defined core devices that support smart services. This NE is applicable to packet transport networks. It is the first 10T-level SPTN NE in the field. In each slot, a 40GE or 100GE board can be smoothly replaced with a 400GE board. A PTN 7900 NE supports smart services, visualized traffic, and the predicable capacity. With the new software-defined networking (SDN) architecture, the PTN 7900 NE effectively supports Long Term Evolution (LTE) and various services.
