Fibre Channel Physical Layer
Transceivers
SFPs/SFFs
• Small Form-factor Pluggable/Fixed
• Used with 2 & 4Gb/s FC Devices
• Same architecture as GBICs
• Allow higher port density
• SFF is same form factor, but Fixed and not
pluggable
SFP
Small form-factor pluggable (SFP) transceivers:
Used with 2Gb/s & faster Fibre Channel components
Architecturally similar to GBICs
Smaller form factor supports higher port density
