| Ferrule
|
A rigid
tube that confines or holds a fiber as part of a
connector assembly. |
| Fiber
Distributed Date Interface (FDDI) |
An
ANSI standard to ensure compatibility of components
from different manufacturers. |
| Fiber
Optic Attenuator |
A component
installed in a fiber optic transmission system that
reduces the power in the optical signal. It is often
used to limit the optical power received by the
photo detector to within the limits of the optical
receiver. |
| Fiber
Optic Cable |
A
cable containing one or more optical fibers. |
| Fiber
Optic Link |
A
transmitter, receiver, and cable assembly that can
transmit information between two points. |
| Fiber-in-the-Loop
(FTTL) |
Fiber
optic service to a node that is located in a neighborhood |
| Fiber-to-the-Curb
(FTTC) |
Fiber
optic service to a node connected by wires to several
nearby homes, typically on a block. |
| Fiber-to-the-Home
(FTTH) |
Fiber
optic service to a node located inside an individual
home. |
| FOTP
(Fiber Optic Test Procedure) |
Standards
developed and published by the Electronic Industries
Association (EIA) under the EIA-RS-455 series of
standards. |
| Four
Wave Mixing (FWM) |
Nonlinearity
common in DWDM systems where multiple wavelengths
mix together to form new wavelengths. Most prevalent
near the zero-dispersion wavelength and at close
wavelength spacing. |
| Frequency-division
Multiplexing (FDM) |
A method
of deriving two or more simultaneous, continuous
channels from a transmission medium by assigning
separate portions of the available frequency spectrum
to each of the individual channels. |
| Fresnel
Reflection Loss |
Reflection
losses at the ends of fibers caused by differences
in the refractive index between glass and air. The
maximum reflection caused by a perpendicular air-glass
interface is about 4% or about -14 dB. |
| FUT
|
Abbreviation
for fiber under test. Refers to the fiber being
measured by some type of test equipment. |
