Fibre optic - definition
An optical fibre is a dielectric optical waveguide designed to guide electromagnetic waves in the visible light or near infrared range through the phenomenon of total internal reflection. The key design element of an optical fibre is a core made of a material with a high refractive index, surrounded by a sheath of slightly lower refractive index, which ensures that light is effectively trapped inside the core and propagates over considerable distances with minimal energy loss.
Fibre optics are the primary transmission medium in modern optical communication systems, allowing data to be transmitted at very high bit rates and with minimal delay. They can be single- or multimode, depending on the diameter of the core and the number of possible light propagation modes. In single-mode optical fibres, the optical signal propagates along a single propagation path, which minimises modal dispersion and allows transmission over very long distances, characteristic of transcontinental telecommunications systems.
Fibre-Optic Sensors are also used in optical sensor technology, medicine (e.g. fibre-optic endoscopy), the energy industry and laser systems. Important parameters characterising optical fibres are attenuation of the optical signal, chromatic dispersion, transmission window and mechanical and environmental resistance. Modern optical fibre technologies, such as Wavelength Division Multiplexing (WDM), allow multiple data channels of different wavelengths to be transmitted simultaneously over a single optical fibre, dramatically increasing its throughput. The manufacture of optical fibres requires precise technological processes, such as the VAD, MCVD or OVD method, to control the purity of the material and the structure of the core and jacket layers.
