Fiber Channel Layers
The Open Systems Interconnect (OSI) model breaks communications into seven layers namely, Physical, Data Link, Network,
Transport, Session, Presentation, and Application. Fibre Channel does not follow the ISO model - instead, the protocol has been
broken into five layers: FC-0, FC-1, FC-2, FC-3, and FC-4.
OSI layers versus FC layers
FC-0
defines the physical portions of Fibre Channel, including the media types, connectors, and the electrical and optical
characteristics needed to connect ports. This level is in the FC-PH standard.
Signaling
Media specifications
Receiver/Transmitter specifications
FC-1
defines the transmission protocol, encoding, order of word transmission, and error detection. This level is in the FC-PH
standard.
8B/10B character encoding (1/2/4/8G FC) or 64/66B character encoding (10G FC)
Link maintenance
FC-2
defines the signaling and framing protocol, including frame layout, frame header content, and rules for use. It also
contains independent protocols such as login. This is the bulk of the FC-PH standard.
