Future-proof network equipment using copper SFPs and fiber SFPs and XFPs
SFPs and XFPs are compact transceivers which function as modular connectors. Available for copper (RJ-45) and for all common fiber modes, wavelengths and data rates, SFPs and XFPs allow network operators to connect different interface types to the same network equipment, via an SFP/XFP port. The cost of cable upgrades is greatly reduced - preserving the investment in costly networking equipment, for the price of a relatively inexpensive SFP or XFP. More and more network equipment is being designed with SFP/XFP ports, to take advantage of this flexibility, and to take the uncertainty and guesswork out of expensive equipment purchases. Remember to select the SFP or XFP to match the speed of the designated port.
