الملخص EN

spatial division multiplexing (SDM) system has been considered as promising systems due to its ability to transport a higher bit rate for longer transmission distance.

However, nonlinear phase noise (NPN (degrades SDM system performance.

In this paper, we propose return-to-zero (RZ)-coded phase-conjugated twin waves (PCTWs) to improve the effectiveness of nonlinear distortion cancellation in the SDM system.

In this approach, the PCTWs are modulated by m-array quadrature amplitude modulation (mQAM) then RZ encoded.

After that, RZ-mQAM PCTWs are co-propagated over two fibres links.

The received signals are superimposed to suppress the NPN.

An analytical model that characterizes the performance of spatial-multiplexed (SM) RZ-coded PCTWs scheme is developed.

Moreover, we numerically investigate the system performance with 4QAM format at 20Gsymbol/s rate.

The results display that the performance is substantially better for the proposed scheme.

Transmission reaches of both 4QAM PCTWs and RZ-4QAM PCTWs schemes are extended by 77.

8% and 100%, respectively, in contrast with the 4QAM scheme.
