Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In fiber optics, the radiation angle is half the vertex angle of the cone of light emitted at the exit face of an optical fiber. The cone boundary is usually defined (a) by the angle at which the far-field irradiance has decreased to a specified fraction of its maximum value or (b) as the cone within which there is a specified fraction of the total radiated power at any point in the far field.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In fiber optics, the radiation angle is half the vertex angle of the cone of light emitted at the exit face of an optical fiber. The cone boundary is usually defined (a) by the angle at which the far-field irradiance has decreased to a specified fraction of its maximum value or (b) as the cone within which there is a specified fraction of the total radiated power at any point in the far field. An optical fiber is made up of the core(carrying the light pulses), the cladding (reflecting the light pulses back into the core) and the buffer coating (protecting the core and cladding from moisture, damage etc.). Together, all of this creates a fiber optic which can carry up to 10 million messages at any time using light pulses.
