The record was set via 1.5 terabits per second super channel transmission over 870 kilometres between Warsaw and Wroclaw. Nokia and Orange Poland have achieved the world’s first optical transmission of 250 gigabits per second per wavelength over 870 kilometres. The record was set through Orange Poland’s existing network infrastructure. The results are a 25 per cent increase in per-wavelength capacity over 200 Gb/s, a 70% distance improvement versus comparable field trials and a 250% increase in bandwidth over 100 Gb/s networks using same amount of spectrum. “Reaching these new heights in optical transmission proves we can meet bandwidth demand while maintaining a low cost per bit,” says Christian Gacon, vice president of Orange’s transport networks.
