In cable, all of these waves travel at about 67 to 95% of the speed of light. This tool does not take into account any additional delays that may be introduced by communication protocols, routing, encryptions, data transformation, etc. Light travels slower in a fiber than it does in free space (air or vacuum) due to the index of refraction of glass. The refractive indices of each material are engineered to ensure that light always reflects back off the cladding and is never absorbed by.
