Optoscribe and Sumitomo Electric Industries have teamed up with the University of L’Aquila, Italy for an experimental research project to help strengthen the telecommunications infrastructure of the city.

Nippon Telegraph and Telephone (NTT) and six partners have established a new world record of 118.5Tb/s for the largest transmission capacity achieved over an optical fibre of standard dimensions.

Though the optical fibre had the same diameter as standard singlemode fibre, its structure was not standard. The design contained four cores (light paths) running along the fibre’s length.
