Abstract
Disclosed herein are methods, structures, and devices that provide multi-range frequency domain compensation of chromatic dispersion within optical transmission systems that offer significant operational power savings. More specifically, a method of operating frequency domain filtering structures and circuits including FFT, frequency-domain filter multiplication and iFFT functions at a lower duty cycle for shorter overlap such that significant power savings is realized.
