AI Technical Summary
Technical Problem
Existing optical transmission systems face challenges in accurately compensating for nonlinearity due to attenuation in electrical components, making it difficult to obtain a level diagram necessary for calculating compensation coefficients.
Method used
An optical transmission system with pre-equalization units, digital-to-analog and analog-to-digital converters, and scale/coefficient estimation units to accurately determine and compensate for nonlinearity by correlating amplitude distributions and calculating filter coefficients.
Benefits of technology
The system enables precise compensation, improving signal-to-noise ratio (SNR) and waveform consistency by accurately determining output levels and filter coefficients.
