The D-Link DES-1048G is a high port-density unmanaged 10/100Mbps switch designed for cost-effective workgroup connection. With 48 10/100Mbps ports and 2 SFP in a low-profile rack-mountable box, this switch provides very low-cost connections for 48 workstations, plus 2 flexible Gigabit connections to 2 servers.

48 10/100Mbps Ports for Workstations Connection
The switch provides 48 10/100Mbps ports supporting autosensing and auto-negotiation of network speeds and full/half duplex. These ports can connect to workstations and print servers, giving each a dedicated bandwidth. All ports support auto MDI/MDIX cross-over, allowing you to connect to any node without the need to change your usual straight-through twisted-pair cables.

2 Mini GBIC Ports
Two SFP (Mini GBIC) are provided for fibre Gigabit connections. You can select to install optional transceivers in the SFP slots for short, medium or long-distance fibre backbone attachment.

Flow Control for Secure Transmission
802.3x standard flow control minimizes dropped packets by sending out collision signals when the port's receiving buffer is full. This function support allows you to deploy Gigabit servers operating at 2000Mbps full duplex mode for simultaneous access from workstations.
