2. Signal Analysis: After the signal is detected, the next step is to analyze the characteristics of the signal. This includes analyzing the frequency components, time characteristics, and other parameters of the signal. By analyzing the characteristics of the signal, it is possible to identify the factors causing light degradation and determine the appropriate compensation method.
3. Compensation Algorithm: Based on the analysis of the signal characteristics, various compensation algorithms are used to restore the original signal quality. Common compensation algorithms include: equalization, filtering, and adaptive compensation. These algorithms can effectively compensate for the dispersion, attenuation, and noise of the light signal, thereby improving the transmission quality.
