Abstract
A coherent fiber-optic transmission systems of OFDM signals is considered. The channels are formed using spectral-efficient modulation formats (QPSK and M-QAM). The influence of nonlinear phase noise arising in an optical fiber on channel signals is studied. It is shown that nonlinear phase noise appearing in the optical path is converted into amplitude noise and, mixing with the noise of optical amplifiers, leads to a decrease in the signal quality factor. Estimation formulas for determining the noise immunity of channel signals by calculating the Q-factor are given.
