Artificial Intelligence (AI) refers to the development of computer systems or algorithms that can perform tasks that typically require human intelligence. These tasks include problem-solving, learning, understanding natural language, speech recognition, visual perception, and decision-making. AI aims to create machines capable of mimicking cognitive functions associated with human intelligence, allowing them to adapt, learn from experience, and execute tasks autonomously.

Evolution from 8QAM live traffic to PCS 64-QAM with Neural-Network Based Nonlinearity Compensation on 11000 km Open Subsea Cable

/in /by

We report on the evolution of the longest segment of FASTER cable at 11,017 km, with 8QAM transponders at 4b/s/Hz spectral efficiency (SE) in service. With offline testing, 6 b/s/Hz is further demonstrated using probabilistically shaped 64QAM, and a novel, low complexity nonlinearity compensation technique based on generating a black-box model of the transmission by training an artificial neural network, resulting in the largest SE-distance product 66,102 b/s/Hz-km over live-traffic carrying cable.
