2. Numerical aperture - Wikipedia

   en.wikipedia.org/wiki/Numerical_aperture

   Numerical aperture is commonly used in microscopy to describe the acceptance cone of an objective (and hence its light-gathering ability and resolution), and in fiber optics, in which it describes the range of angles within which light that is incident on the fiber will be transmitted along it.

3. Optical fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   A bundle of optical fibers A TOSLINK fiber optic audio cable with red light shone in one end. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other.

4. Cladding (fiber optics) - Wikipedia

   en.wikipedia.org/wiki/Cladding_(fiber_optics)

   The numerical aperture of a multimode optical fiber is a function of the indices of refraction of the cladding and the core: Diagram showing how the light refracts at the core/cladding interface. With the angle of refraction being dependent upon the difference in index of refraction, n, of core and cladding.

6. Normalized frequency (fiber optics) - Wikipedia

   en.wikipedia.org/wiki/Normalized_frequency...

   In an optical fiber, the normalized frequency, V (also called the V number), is given by = =, where a is the core radius, λ is the wavelength in vacuum, n 1 is the maximum refractive index of the core, n 2 is the refractive index of the homogeneous cladding, and applying the usual definition of the numerical aperture NA.
