Dispersion-managed optical link with optical phase conjugator (OPC) at the midway is well known for the compensation technique of optical signal distortion due to group velocity dispersion and fiber nonlinearities. However, in this link, the midway position of OPC restricts the flexible optical link configuration. That is, the OPC position has to get out of the midway for implementation of the flexible link configuration. Therefore, the proponents of this study demonstrated the compensation effect of the non-midway OPC in dispersion-managed optical link on the distorted wavelength division multiplexed (WDM) channels. It is confirmed in this study that the non-midway OPC is somewhat effective in the compensation depending on the detailed link parameters. It is also confirmed that when the OPC was moved to transmitter or receiver of WDM system from the midway, it becomes desirable to control the net residual dispersion (NRD) in one transmission section having the lower fiber span number, and simultaneously select the start fiber span of that transmission section as the position of NRD control.
