Dispersion Managed Optical Links with Optical Phase Conjugator Placed at the Various Positions

Abstract

The needs of ultra-high optical backbone systems are currently increased to transmit the high-quality multimedia services. For transmitting the ultra-high speed optical signals with better performance, the techniques to suppress or mitigate the optical signal distortion due to group velocity dispersion and optical Kerr effects are required. Dispersion management (DM), optical phase conjugation, and the combination of these two are promising techniques to compensate for the signal distortion. The goal of this paper is to investigate the possibility of the flexible configurations of the ultra-high and long-haul optical backbone systems using optical links with the random distribution of residual dispersion per span (RDPS) and optical phase conjugator (OPC) placed at the various positions. We confirm that the proposed link configurations should be one of the methods suitable for implementing the flexible optical backbone systems, also, the possibility is more available to longer backbone.
