This cost effective Gigabit Switch provides an affordable solution for administrators to upgrade their networks to high
speed Gigabit connections. The dedicated stacking ports offer up to 40G bi-directional bandwidth, which makes the
DGS-3120 Series also suitable as a backbone solution for SMBs. The advanced ACL and user authentication
functions on the Switch extend the network security coverage from core to the edge. A unique D-Link Safeguard
Engine protects the DGS-3120 Series from the threat of worms and viruses, thereby increasing overall reliability,
serviceability, and availability
The Switch has a combination of 1000BASE-T ports and SFP ports that may be used in uplinking various network
devices to the Switch, including PCs, hubs and other switches to provide a gigabit Ethernet uplink in full-duplex mode.
The SFP (Small Form Factor Portable) combo ports are used with fiber-optical transceiver cabling in order to uplink
various other networking devices for a gigabit link that may span great distances.
These SFP ports support full-duplex transmissions and can be used with the following transceivers:
•
DEM-310GT (1000BASE-LX)
•
DEM-311GT (1000BASE-SX)
•
DEM-312GT2 (1000BASE-SX)
•
DEM-314GT (1000BASE-LH)
•
DEM-315GT (1000BASE-ZX)
•
DEM-210 (Single Mode 100BASE-FX)
