“…Fortunately, systems combining DM and optical phase conjugation have been proposed to address these drawbacks [13,14,15]. Studies have demonstrated 960 Gbps (40 Gbps × 24 channels) WDM transmission with satisfactory system performance by applying both DM and an OPC [16,17,18]. Nevertheless, the dispersion-managed optical link configurations are still symmetry with respect to OPC position in systems combining DM and optical phase conjugation.…”

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.

In long-haul optical communication systems consisting of single-mode fiber spans and fiber amplifiers, such as an erbium-doped fiber amplifier, signal distortion causes performance to deteriorate because of group velocity dispersion and fiber nonlinearity. A combination of dispersion management and optical phase conjugation is an effective technique of compensating for the distortion. In an optical link configured with this combination, the dispersion map mainly affects the compensation for the distorted optical signals. Improvements in system performance have been reported for various types of dispersion maps. In this study, a symmetric type of dispersion map with respect to the midway optical phase conjugator is proposed. The effect of the proposed dispersion maps on the compensation for the distorted 24 channel × 40 Gbps wavelength-division-multiplexed signals was assessed through numerical simulation. It was confirmed that antipodal-type dispersion maps are most appropriate for the compensation, as well as for the flexibility of the link configuration.
