D-Link DEM-311GT 1-Port Mini GBIC SX Multi Mode Fiber Transceiver

This transceiver uses the industry-standard Small form Pluggable (SFP) package. It slides into the mini-GBIC slot of the Gigabit device. Like all D-Link mini-GBIC transceivers, it is hot-swappable: you can remove or replace the transceiver with the system powered on, which allows modules to be added or swapped without interrupting the network.
