With high Gigabit port densities, Gigabit SFP, 10-Gigabit SFP+ support, and advanced software solutions, these switches can act as either a departmental access layer or aggregation switches to form a multilevel network. Service providers can take advantage of the high SFP density (DGS-3420-28SC) to structure the aggregation of Fiber to the Building (FTTB) networks that can be extended to subscribers' sites. Unparalleled Flexibility Easily deployed and simple to manage, the DGS-3420 can be stacked with any switch that supports D-Link's Single IP Management to form a multi-level network with centralized management. The virtual stack can include units located anywhere on the same network domain and uses optional 10-Gigabit uplinks to move intra-stack traffic at 20 Gbps full duplex speeds. Redundant Ring Stacking Alternatively, depending on whether linear or ring stacking is implemented, users can use one or two 10-Gigabit SFP+ ports to create a physical stack. 12 units or 576 Gigabit ports can be configured for a stack using direct attach cables to provide high-bandwidth and return on investment.
