PTN 7900E

The PTN7900E is Huawei’s next-generation metro transport device mobile service bearer. It is mainly positioned at the metro aggregation and core layers and backbone networks to carry mobile services and VIP private line services. The PTN 7900E series has three product forms: PTN 7900E-32, PTN 7900E-24, and PTN 7900E-12. The PTN 7900 series products support 40GE/50GE/100GE/200GE/400GE ultra-large ports, intelligent service monitoring, visualized traffic, measurable quality, and predictable capacity. The new SDN architecture supports mobile-transport functions such as SR-TP and FlexE, effectively supporting the long-term development and evolution of carriers' mobile service bearer networks.
