fiber optics Branch of optical technology concerned with the transmission of light
pulses through fibers made of transparent materials such as glass,
fused silica, and plastic.
fibre Physical media types supported by the Fibre Channel specification,
such as optical fiber, twisted pair, and coaxial cable.
Fibre Channel Integrated set of standards recognized by ANSI which defines
specific protocols for flexible information transfer. Logically, a
point-to-point serial data channel, structured for high performance.
Fibre Channel fabric
element

recorded in a management information base (MIB) which can be
accessed by fabric management software.
Fibre Channel I/O
controller
Controls the embedded Fibre Channel port and configures the ports’
ASICs.
fibre port module card Each fiber port module card provides four Fibre Channel connections
through duplex small form factor pluggable (SFP) fiber-optic
transceivers.
field-replaceable unit Assembly removed and replaced in its entirety when any one of its
components fails.
firmware Embedded program code that resides and executes on the switch.
FLASH memory A computer chip with a read-only memory that retains its data when
the power is turned off and that can be electronically erased and
reprogrammed without being removed from the circuit board.
F_Port See fabric port.
frame A variable-length packet of data that is transmitted in frame relay
technology.
FRU See field-replaceable unit.
Fx_Port A configurable port type that restricts a port to operate either as an
F_Port or FL_Port.
