Addon's industry-standard SFP is a hot-swappable input/output device that plugs into a gigabit Ethernet slot, linking the port with the fiber-optic network. Addon's transceivers (GBIC, SFP, XFP) are 100% compliant for all of our networking product lines. Add-on transceivers are factory loaded with OEM specific configuration data required for networking compliance. These transceivers initialize and perform identically to the OEM transceivers and can be mixed and deployed with other OEM or 3rd party transceivers, for seamless network performance.
