Integrated analysis of communication networks from the IP layer to the physical (optical) layer offers a multitude of advantages over analysis of each separate layer.

Beyond 100G

In the core part of the network, the current challenge is to increase the transported data capacity per wavelength channel to over 100 Gbit/s (Beyond 100G).

Digital signal processing (DSP) in the electrical domain is an enabling technology for coherent optical transport systems. It is employed for carrier recovery and mitigation of linear as well as nonlinear impairments in digital coherent receivers.
