fiber
Physical media types supported by the Fibre Channel specification, such as optical fiber,
copper twisted pair, and coaxial cable.
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.
fiber port module (FPM) card
Each fiber port module card provides four Channel connections through duplex small form
factor pluggable (SFP) fiber-optic transceivers. 1 gigabit per second enabled. See also
universal port module card.
Fibre Channel
Integrated set of standards recognized by the American national Standards Institute (ANSI)
which defines specific protocols for flexible information transfer. Logically, a point-to-point
serial data channel, structured for high performance.
Fibre Channel input/output controller (FCC-IOC)
A device that controls the embedded Fibre Channel port and configures the ports’ ASICs.
field-replaceable unit (FRU)
Assembly removed and replaced in its entirety when any one of its components fails.
firmware
Embedded program code that resides and executes on the director.
FPM card
See fiber port module card.
F_Port
See fabric port.
FICON
An IBM set of products and services that is based on the Fibre Channel Standard. FICON
technology uses fiber-optic cables as the data transmission medium and significantly improves
I/O performance (including 1 Gb/s bidirectional data transfer).
