Despite the modern world relying heavily on digital optical communication, there has not been a significant improvement in the minimum attenuation—a measure of the loss of optical power per kilometer traveled—of optical fibers in around 40 years. Decreasing this loss would mean that the signal could travel further without being amplified, leading to more data being transmitted over longer distances, faster internet and more efficient networks.
