Different Types, Features and Advantages of Cisco Gigabit Ethernet SFP Modules

SFP stands for Small Form-factor Pluggable. It is widely used in the field of Data Communication and Networking. Small Form-Factor Pluggable (SFP) Gigabit Interface Converter is a hot swappable I/O device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. These SFPs mainly acts as an interface between a networking device like any Switch, Router, Repeater, Multiplexer etc and its interconnecting cable. The interconnecting cable may be made of copper or it can be an optical fiber cable. Certain SFP also use copper cables as interface. This will cause a device in the network to send their data over shielded or unshielded twisted pair cable. Usually such copper cable interfaces are used when the information to be transmitted needs to cover only shorter distances where use of copper cable is more economical than optic fiber cables. Find copper and Fiber SFPs in figures below. […]
