Following explanation to the terms that you should know about Fiber Optic Tapers.
1.Fiber Diameter (Pitch)
Diameter of a fiber strand / Distance between fiber centering
2.Numerical Aperture
Capability of light gathering of fiber optic components.
3.Resolution
The measure of how closely lines can be resolved in one milimeter
4.EMA
Extra Mural Absorption(EMA) are small black fibers that inserted between 2 fiber strands. Which will absorb stray light between fibers.
5.Core
The transmitting part of the fiber optic wave guide. (Core usually has higher refraction index than cladding)
6.Cladding
The cover outside core, cladding has a lower index of refraction than core.
7.Packing Fraction
Ratio of Core area to Total area, this will shows the light transmission efficiency of the component.
9.Transmission
Comparison between Output light intensity and Input Light Intensity
10.Optical Crosstalk
The light escape from one fiber strand and get into another fiber.
11.Blemish
Blemishes are the area where transmission is reduced. Blemish is caused by contaminants along in the fibers.
12.Chickenwire
Chicken wire appear likes a black line on the components. The result of chicken wire is due to mal-control of temperature or pressure during the procedure.
13.Coefficient Thermal Expansion
CTE defined as the changing of dimension when the fiber components exposed to changing temperature environment
14.Shear Distortion
Shear distortion is cause by the misalignment of fiber during fusion process.
15.Gross Distortion
Gross Distortion is cause by in-proper Temperature/Pressure and Material input procedure.
