Dispersion Managed Optical Links with Randomly Distributed Residual Dispersion Per Span for 960 Gbps WDM Transmission
The possibility of implementing the randomly distributed residual dispersion per span (RDPS) in optical links with optical phase conjugator (OPC) for 960 Gbps WDM transmissions is studied and discussed. It is confirmed that RDPS of each fiber spans should be randomly selected to ensure that the deviation of the accumulated dispersion between two transmission sections with respect to OPC was set to be small, for example, RDPS of each fiber spans are randomly selected to ensure that the accumulated dispersion at each transmission sections are to −10~20 ps/nm for optical link with net residual dispersion (NRD) of 10 ps/nm. It is also confirmed that the best NRD in optical link with the randomly distributed RDPS is ±10 ps/nm rather than 0 ps/nm. Consequently, the randomly distributed RDPS is possible by applying the best NRD into optical link specified with the optimal combination condition of random RDPS.
