Interoute and Infinera have completed a demonstration of Infinera’s new 500 Gbps photonic integrated circuits (PICs), successfully delivering 100 Gbps channels on the Interoute pan-European network. Interoute was the first in Europe to deploy Infinera’s 100 Gbps PICs more than three years ago and is planning to use Infinera’s next generation systems based on 100 Gbps channels enabled by 500 Gbps PICs.
The demonstration took place between Amsterdam and London. The 100 Gbps channels originated in Amsterdam and traveled under the North Sea to London, where they were looped back and returned to Amsterdam, for a total distance of 940 kilometers (km). The signals were received error-free despite a lengthy unrepeatered subsea link of 210 km between the Dutch and English coasts.
The coherent 100 Gbps channels were transmitted on fiber simultaneously carrying 200 Gbps of live traffic over 10 Gbps channels, demonstrating that the Infinera Line System (ILS) can carry both types of optical signals without interference.
