Novel hollow-core optical fiber transmits data 45% faster with record low loss

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.
