Dispersion Managed Optical Links with Randomly Distributed Residual Dispersion Per Span for 960 Gbps WDM Transmission

Compensation Characteristics of the Distorted WDM Signals Depending on the Variation Degree of RDPS Random Variables in the Optical Links with Dispersion Management and Optical Phase Conjugation

“…EOPs are narrow than other NRDs. These optimal NRDs are consistent in the results of our previous research of [13]. We also confirm that the optimal NRDs of the considered other launch power (-9~3 dBm) are obtained to be the same values, i.e., 10 ps/nm or -10 ps/nm.…”

“…This scheme means that the lengths of SMF and DCF have to be fixed, hence the uniformly distributed RDPS makes the optical link configurations simple, but the implementation of reconfigurable optical link is very difficult. The authors have shown the possibility of implementing the flexible optical links for wavelength division multiplexing (WDM) transmission by applying the randomly distributed RDPS into combined DM and OPC links [13]. In previous research, the random distribution of RDPS were made by selecting the random variables of DCF length for each fiber spans with the fixed SMF length.…”

The Flexible Dispersion-managed Optical Links with a Randomly Distributed RDPS

“…2 (a) and (b) illustrate the EOPs of the worst channel among the 24 WDM channels with the launch power of -5 dBm as a function of the NRD controlled by pre-and postcompensation, respectively, in the optical transmission links with the randomly distributed RDPS. It is confirmed that the optimal NRDs were found to be 10 ps/nm or -10 ps/nm in the optical link controlled by precompensation and postcompensation, respectively, which are the same result with our another research of [6]. We also confirm that the optimal NRDs are consistent in the considered launch power (-9~3 dBm).…”

“…We consider the same configurations and parameters of WDM transmitter(Tx), WDM receiver(Rx) and OPC with those of [6].…”

“…As far as the authors know, the analysis and assessment of the optical transmission link to which OPC and DM are applied, with the non-uniform distribution of RDPS in every fiber span, have not been reported yet. Authors had shown the possibility of the flexible optical link configurations using the randomly distributed RDPS in 960 Gbps (40 Gbps × 24 channels) wavelength division multiplexing (WDM) transmission system [6].…”
