PTN7900 - Huawei

PTN 7900

PTN 7900s are next-generation packet metropolitan packet transport devices based on the 400G platform. They provide Tbps-level capacity and 100GE or higher bandwidth, and support service intelligentization and SDN. PTN 7900s are mainly used at the core/aggregation layer of a metropolitan transport network and provincial/national backbone networks to construct a bearer network for mobile services and VIP leased line services.

PTN 7900 series products support 40GE/100GE/200GE interfaces and are characterized by intelligent service monitoring, visualized traffic, assessable quality, and predictable capacity. PTN 7900s use a new SDN architecture to effectively support long-term network development and evolution.
