**Small Form-factor Pluggable (SFP)** is a transceiver module. There is an array of SFPs with different data rate from 10Mbps to 100Gbps and compatible with different media such as copper, [[Fiber Optic Cables#Multimode Fiber (MMF)]] or [[Fiber Optic Cables#Single Mode Fiber (SMF)]]. They plug into the SFP port of a device such as a network switch. This allows the user to easily adapt to the network environment by choosing the appropriate SFP. # SFP+ The main difference between SFP and SFP+ is that the **SFP+ is used in Gigabit Ethernet applications while SFP is for 100Bse or 1000Base applications**.^[[SFP_vs_SFP+_What_is_the_Difference_and_How_to_Use.pdf (inscapedata.com)](https://www.inscapedata.com/pdf/SFP_vs_SFP+_What_is_the_Difference_and_How_to_Use.pdf)]
