The Gigabit SFP Transceivers use the Small Form-factor Pluggable (SFP) design. They provide
the necessary signal amplification for data to be transmitted to the network cable from the
port, and vice versa. The SFP form factor is advantageous because it is smaller than other form
factors such as Xenpak, X2, and 10G XFP, ensuring lower costs, lower power disruption, and
higher port density.
