S-Band Transmission with Off-the-Shelf C-Band Components Enabled by Nonlinear Predistortion based on Coherent System Identification

In order to cope with the rapid traffic growth while at the same time reducing the cost-per-bit, one of the main objectives for operators is the efficient reuse of the legacy optical fiber infrastructure. This is highly desirable as fibers represent a valuable asset in the network. To achieve this objective, multiband (MB) or ultra-wideband (UWB) dense wavelength division multiplexing, in combinat...
