The transmission of radiant energy through transparent fibres of glass, plastic or fused silica.
Result of curvature of the fibre and/or small distortions in the fibre producing increased attenuation.
Outer concentric layer surrounding the fiber core, having a lower index of refraction.
Centre section of the optical fibre carrying the light.
Material immediately covering the optical fibre to preserve the integrity of the fibre.
Material whose index of refraction is almost equal to that of the fibre core and is used to minimize Fresnel reflections.
Curvature of a fibre which causes loss of light.
Microscopic bends and bumps in the fibre which cause loss of light by scattering.
A term used to describe an independent light path through a fibre, as in multimode or single-mode:
Energy exchange between modes of light propagating in an optical fibre.
Single Mode Fibre An optical fibre that supports only one mode of light propagation above the cutoff wavelength.
Multimode Fibre An optical waveguide in which light travels in multiple modes.
