FCC Class B This certification label appears on electronic devices that can be used in
either a home or a commercial environment within the United States.
FCP The mapping of SCSI-3 operations to Fibre Channel.
FDDI Fiber Distributed Data Interface. An ANSI standard for 100 megabaud
transmission over fiber optic cable.
FD SCSI The fast, narrow, differential SCSI bus with an 8-bit data transfer rate of 10
MB/s.
See also FWD SCSI and SCSI.
fiber A fiber or optical strand used in fiber optic cable. Spelled fibre when used in
“Fibre Channel” protocol.
See also Fiber Optic Cable, Fibre Channel.
fiber optic cable A transmission medium designed to transmit digital signals in the form of
pulses of light. Fiber optic cable is noted for its properties of electrical
isolation and resistance to electrostatic contamination.
Fibre Channel An ANSI standard name given to a low-level protocol for a type of serial
transmission. The Fibre Channel specifications define the physical link, the
low level protocol, and all other pertinent characteristics.
FL_Port A port in a fabric where N_Port or an NL_Port may be connected.
See N_Port, NL_Port, and F_Port.
See also fabric.
frame Frame is the basic unit of communication using the Fibre Channel protocol.
Each frame consists of a payload encapsulated in control information. The
initiator breaks up the exchange into one or more sequences, which in turn
are broken into one or more frames. The responder recombines the frames
into sequences and exchanges.
See also Initiator.
GBIC Gigabit Interface Converter. The hardware devices inserted into the ports of
the Fibre Channel switch that hold the Fibre Channel cables. Converts fiber
optic cable connections to Fibre Channel switch connections
