      Hey Y’all,

      I’m trying to calculate the FWM crosstalk using optisystem 14 and I dont know how to calculate it, IM using diffrent modulations formats which re MDRZ DRZ RZ and NRZ,

      Anyone knows How to calculate that please ?

      Hi.
      A particular signal can accumulate cross-talk from different elements and channels over the network. Cross-talk can be reduced by using several techniques such as wavelength dilation or filter cascading. In this example, we will investigate the effect of interchannel cross-talk at ADM to a ring network. The project is found in the Interchannel crosstalk at ADM in a ring network.osd file. This network contains 4 nodes that communicate over two channels at 193 THz and 193.1 THz. The bit rate is 10 Gbps. ADMs at each node is modeled by using WDM add and WDM drop components. WDM add and drop components are created by using 4th order Bessel filters. The ring is ended with a ring control component which can circulate the signals around ring for a given number of times. The distance between nodes is 12.5 km and we inserted an ideal amplifier just before node 2 to compensate for the total fiber loss in the ring. Dispersion and nonlinear effects of fibers are disabled to isolate the crosstalk effect.

      Thanks
