The new generation xStack DGS-3620 series switches provide high performance, flexibility, security, multi-level QoS and backup power to networks of large enterprises and small and medium-sized businesses (SMBs). The switches provide high density gigabit ports for connecting workstations, equipped with SFP ports and 10 Gigabit SFP + and support advanced software functions. The switches can be used as unit access level devices or in the core of the network to create a multi-level network structure with high-speed backbones and centralized connection of servers. Service providers can also take advantage of switches with a high density of SFP ports to form an optical network core (FTTB).
