IMC Networks' IE-SFPs, SFP+'s and XFPs are compact transceivers which function as modular connectors. Available for copper (RJ-45) and all common fiber modes, wavelengths and data rates, they allow network operators to connect different interface types into the same network equipment, via an SFP/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, SFP+ or XFP. More and more network equipment is being designed with these ports to take advantage of their flexibility, and to take the uncertainty and guesswork out of expensive equipment purchases.
