Researchers from the Network System Research Institute of the National Institute of Information and Communications Technology (NICT, Japan) have achieved the world's first transmission exceeding 1 petabit per second (125,000 Gbps) in a single-core multi-mode optical fiber. This beats the current record transmission in a multi-mode fiber by 2.5 times.
"To date, transmission experiments in optical fibers supporting large number of modes were limited to small optical https://interestingengineering.com/graphene-may-be-the-key-to-meeting-all-future-bandwidth-demands">bandwidths. In this study, we demonstrated the possibility of combining highly spectral efficient wideband optical transmission with an optical fiber guiding 15 fiber modes that had a cladding diameter in agreement with the current industry standard of 0.125 mm," wrote the researchers in a statement.
