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.
A simplified, system-agnostic NLC algorithm based on a neuron network is proposed to pre-distort symbols at transmitter side to demonstrate ~0.6dB Q improvement after 2800km SMF transmission using 32Gbaud DP-16QAM.
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.
