Ferrule |
A small alignment tube attached to the end of the fiber
and used in connectors. These are made of stainless
steel, aluminum, zirconia, or plastic. The ferrule is used
to confine and align the stripped end of a fiber so that it
can be positioned accurately.

Fiber |
A single, separate optical transmission element characterized
by core and cladding. The fiber is the material
that guides light or waveguides.

Fiber channel |
A gigabit interconnect technology that, through the
8B/10B encoding method, allows concurrent communications
among workstations, mainframes, servers, data
storage systems, and other peripherals using SCSI and IP
protocols.

Fiber curl |
Occurs when there is misalignment in a mass or ribbon
splicing joint. The fiber or fibers curl away from the joint
to take up the slack or stress caused by misalignment of
fiber lengths at the joint.

Fiber identifier |
A testing device that displays the direction of travel of
light within an optical fiber by introducing a macrobend
and analyzing the light that escapes the fiber.

Fiber optics |
The optical technology in which communication signals
in the form of modulated light beams are transmitted
over a glass or plastic fiber transmission medium. Fiber
optics offers high bandwidth and protection from electromagnetic
interference and radioactivity; it also has
small space needs.

Fiber test equipment |
Diagnostic equipment used for the testing, maintenance,
restoration, and inspection of fiber systems. This equipment
includes optical attenuation meters and optical
time-domain reflectometers (OTDRs).

|
Fiber-optic attenuator |
An active component that is installed in a fiber-optic transmission
system that is designed to reduce the power in the
optical signal. It is used to limit the optical power received
by the photo detector to within the limits of the optical
receiver.
