- Abstract
- In high-capacity and long-haul optical communication systems, signal distortion is induced by the group velocity dispersion (GVD) and nonlinear Kerr effects of optical fibers. In this paper, we analyze the effects of the dispersion compensating fiber (DCF)'s position and the control position of the net residual dispersion (NRD) on the system performance in dispersion-managed (DM) wavelength division multiplexed (WDM) transmission links with the midway optical phase conjugator (OPC). It is confirmed that the desirable fiber arrangements to more improve the performance of WDM channels are the SMF then the DCF and are the DCF then the SMF before and after OPC, respectively. We also observed that the best concentrating position for the NRD control is obtained by postcompensation, i.e., by using the DCF in the last fiber span. © 2016 International Information Institute.
