Summary
Researchers have developed a novel hollow-core optical fiber that achieves record-low signal attenuation, transmitting data 45% faster than conventional fibers. This breakthrough represents the first significant improvement in optical fiber minimum attenuation in approximately 40 years, potentially enabling longer transmission distances without amplification, faster internet speeds, and more efficient network infrastructure.
Key quotes
· 3 pulledDespite the modern world relying heavily on digital optical communication, there has not been a significant improvement in the minimum attenuation 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.
