Dense Wavelength Division Multiplexing (DWDM) Small Form-Factor Pluggable (SFP) transceivers provide the high speeds and physical compactness that today's networks require while delivering the deployment flexibility and inventory control that network administrators demand. They are designed to Multi-Source Agreement (MSA) standards to ensure broad network equipment compatibility. As multirate interfaces they support any protocol from 100 Mbps to 4.25 Gbps, for 8G/10G please see SFP+ category. The transceivers are small form factor pluggable modules for bi-directional serial optical data communications such as 4x/2x/1x Fibre Channel, SDH/SONET, Ethernet applications. The modules meet the requirements of the IEEE802.3 Gigabit Ethernet standard and ANSI Fibre Channel specifications, and are suitable for interconnections in Gigabit Ethernet and Fibre Channel environments.
