World record transmission of 172 Tb/s over 2040km distance coupled-3-core multi-core fiber

EurekAlert  April 2, 2020
Using the product of data-rate and distance as a general index of transmission capacity, researchers in Japan achieved 351 petabit/s x km, more than doubling the current world record in standard outer diameter optical fibers employing space-division multiplexing. The coupled-core multi-core fiber requires signal processing on the receiving side after transmission, but the signal processing load is less compared to more commonly investigated few-mode fibers. The fiber has the same outer diameter as standard optical fibers which allows converting such a fiber into a cable with existing technologies and equipment, simplifying a timely adoption of coupled-core multi-core fibers in the industry…read more.
