TRENDnet's 1000BASE-T RJ-45 Copper SFP Module, model TEG-MGBRJ, converts a standard SFP slot into a RJ-45 gigabit port for additional copper connectivity. This SFP module works with standard SFP slots commonly found in network switches and fiber media converters. Save on equipment costs by repurposing a switch's unused SFP slots for copper connectivity. RJ-45 Copper SFP Take advantage of unused SFP slots and repurpose them with RJ-45 copper Ethernet connectivity.
