OptiX PTN 7900 is a new generation large-capacity, large-bandwidth, service-intelligent packet transport core equipment. It is the industry's first SDN-based PTN product, supporting 40GE/50GE/100GE/400GE large ports, service intelligence, traffic visualization, quality evaluable, and capacity predictable. It adopts a new SDN architecture to effectively support long-term enterprise evolution and multi-service bearing. Huawei took the lead in releasing the SPTN solution in the industry and launched a future-oriented packet transport network that supports multi-service converged bearing, high bandwidth, differentiated quality assurance. It can be applied to core transmission equipment in production networks of industries such as power, transportation, and mining.
Ultra-wide, High-performance Core Bearing:
Supports massive service forwarding to meet core node capacity requirements;
40GE/50GE/100GE/400GE ultra-large bandwidth ports provide unobstructed roads for service opening;
Strong aggregation capability, supports massive base station bearing
Ultra-strong Forwarding Processing, Free Scheduling in the Core Layer:
