Fibre Optic Light Transmitting Concrete is made by using a combination of fibre optic cables and concrete. 2 meters (3-4 feet) deep to reduce the likelihood of accidentally being dug up. In extreme cold climates, cables may need to be buried at greater depths where there temperatures are colder and frost penetrates to. Integrating fiber optics into concrete is an innovative technique that combines the structural strength of concrete with the advanced capabilities of fiber optic technology, enabling applications such as smart monitoring, data transmission, and even aesthetic lighting. These optical fibres are cast into the concrete by threading them through penetrations in the formwork in a desired pattern or constellation before the concrete mixture is poured.
