DES-1228/ME Layer 2 Fast Ethernet Managed Switch
Installing the SFP ports
The DES-1228/ME Switch is equipped with SFP (Small Form Factor Portable) ports, which are to be 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, have auto-negotiation and can be used with the DEM-310GT (1000BASE-LX), DEM-
311GT (1000BASE-SX), DEM-210 (Single Mode 100BASE-FX), DEM-211 (Multi Mode 100BASE-FX), DEM-314GT
(1000BASE-LH), DEM-315GT (1000BASE-ZX), DEM-330T/R (WDM) and DEM-331T/R (WDM) transceivers. See the figure
below for installing the SFP ports in the Switch.
