A guided 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, where The quantity sin θ is the numerical aperture of the fiber. The quantity 2 θ is sometimes called the total acceptance angle of the fiber. This result can be derived from Snell's law by considering
