摘要：
The numerical modeling of short optical pulses propagation in the communication link is carried out. The combination of high chirp and variable dispersion compensation is proposed to suppress the nonlinear noise. The variable dispersion decreases the bit error rate by 10 times. Calculations for 25 ps pulses propagating by 1000 km with 8-level amplitude-phase modulation and two polarization states confirm that the chirp and compensation decrease the nonlinearity effects and improve the quality of detection radically. The results can be useful when choosing a high-speed communication line design. © 2023 Walter de Gruyter GmbH. All rights reserved.
