Term list
This term list gives explanations about fiber and related devices.
B
•
Backscattering: The scattered light which opposes to the previous direction of
propagation.
•
Bandwidth: The function size transmitted by waveguide drop 3db below the zero
frequency. The lowest frequency bandwidth is the function of waveguide length,
but it is not in direct proportion to the length.
C
•
Coating layer: A kind of material coated on the optical fiber in wire drawing pro-
cess to prevent fiber damaged from environment or improper operation.
•
Cladding: Insulating materials coated on the fiber cores.
Appendix
•
Cable pipelines: The pipeline for cable to pave or from it the pipe can be pull.
•
Cable bending radius: Cable bending radius refers to the stress load that cable
suffered, free bend refers to the admissible diameter for it lies under no burdened
state.
•
Cable module: The kind of cable installed by connectors on one end or both
ends, this kind of cable often used as the interconnection by cable system and
optoelectronic devices. If there is only one end installed by the connector, we call it
“tail end fiber”. If both ends installed, we call it “bridging cable or wire jumper”.
D
•
Decibel (dB): Standard unit used to describe the optical power gain or loss.
•
Dielectric: It belongs to nonmetal type, so it is non-conducting, glass optical fiber
is deemed as a kind of dielectric. Medium cable contains no metal parts.
F
•
Fiber core: The central area where light propagates through it. Fiber core ec-
centricity ratio: The core center displacement measurement relative to the cladding
center.
