    摘要: Systems and method of compensating for transmission impairment are disclosed. One such method comprises receiving a wavelength-division multiplexed optical signal. The received optical signal has been distorted in the physical domain by an optical transmission channel. The method further comprises propagating the distorted optical signal backward in the electronic domain in a corresponding virtual optical transmission channel. The backward propagation fully compensates for fiber dispersion, self-phase modulation, and cross-phase modulation (XPM) and partially compensates for four-wave mixing (FWM).

    摘要: A method includes transmitting an optical signal over an optic link in a communication system, the optical link including an optical fiber and optical amplifier; coupling a coherent receiver in the communication system to the optic link for receiving the optical signal; and processing an output from the coherent receiver with digital signal processing DSP in the communication system, the DSP compensating for impairments of the optical signal due to the fiber optic link with an equivalent-link back-propagation.
