In this video, you will find a detailed concept of the Acceptance angle, acceptance cone and numerical aperture of an optical fiber.

Acceptance angle: Maximum incidence angle of a light ray which can be used for injecting light into a fiber core.

Numerical Aperture: sine of half of the angle of fibre's light acceptance cone (angle of acceptance).
