Installing the SFP ports
The DES-3028/28P/52/52P Switches are 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.
