Fibre optics, also known as optical fibre, are a medium and technology used to transmit light along two ends of the fibre. They are widely used in fibre-optic communications where they allow transmission over long distances and at higher data rates (bandwidth) than electrical cables.
The medium of fibre optic is a hair-thin fibre that is often made of glass but sometimes of plastic. The light ray beamed into the fibre, through total internal reflection, can spread within the core to great distances without attenuation or reduction in intensity.
How Fibre Optics Work
Light travels through a fibre optic cable by constantly bouncing off the walls, a phenomenon of total internal reflection. The fibre acts as a waveguide and since the walls of the fibre optic do not absorb light, the light wave can travel great distances.
However, some waves degrade within the fibre due to impurities in the glass. The extent of degradation depends on the wavelength of light transmitted and the purity of the glass.
Types of Fiber-Optic Cables
Fibre optics carry light signals through them in modes. A mode is a path that the beam of light follows through the fibre. A light signal can either go straight down through the middle of the fibre or bounce down the fibre at a shallow angle.
Single-mode – this fibre has a very thin core – about 5 to 10 microns. The light signals travel straight through it without bouncing off the edges. Telephone, cable TV and internet signals are usually carried by single-mode fibres.
Multi-mode – the fibre in this cable is about 10 times bigger than that in a single-mode cable. The information sent can travel over short distances and is mostly used (among other things) to link computer networks.
