A guided ray (also bound ray or trapped ray) is a ray of light in a multi-mode optical fiber, which is confined by the core.. For step index fiber, light entering the fiber will be guided if it falls within the acceptance cone of the fiber, that is if it makes an angle with the fiber axis that is less than the acceptance angle, [1]
Blue fiber cement siding HardiePanel on design-build addition, Ithaca NY. Fiber cement siding (also known as "fibre cement cladding" in the United Kingdom, "fibro" in Australia, and by the proprietary name "Hardie Plank" in the United States) is a building material used to cover the exterior of a building in both commercial and domestic applications.
A multi-mode fiber of index n 1 with cladding of index n 2. A multi-mode optical fiber will only propagate light that enters the fiber within a certain range of angles, known as the acceptance cone of the fiber. The half-angle of this cone is called the acceptance angle, θ max.
Although fiber cement flat sheet may be classified under EN 12467:2012+A2:2018 in Category A1 (non-combustible - construction applications), A1Fl (non-combustible - flooring applications) or A2 (limited combustibility), some fiber cement sheet does not test as well. Additionally, some products may not have been tested by any accredited lab at all.
Rays of light enter the fiber with different angles to the fiber axis, up to the fiber's acceptance angle. Rays that enter with a shallower angle travel by a more direct path, and arrive sooner than rays that enter at a steeper angle (which reflect many more times off the boundaries of the core as they travel the length of the fiber).
Acceptance angle may refer to: Half of the angular aperture of an optical system Acceptance angle (optical fiber) , the angle in an optical fiber below which rays are guided rays

Miami-Dade County was the first in Florida to certify hurricane-resistant standards for structures which the Florida Building Code subsequently enacted across all requirements for hurricane-resistant buildings. Many other states reference the requirements set in the Florida Building codes, or have developed their own requirements for hurricanes ...
