Wavelength converter-reshaper operating at 10 Gbit/s in dispersion shifted fibre

We demonstrate experimentally a wavelength converter-reshaper, operating at 10 Gbit/s, in a dispersion shifted optical fibre; due to the Kerr nonlinearity, it is able to generate a large number of signal replicas that permit the ITU-grid to be covered. We performed transmission experiments on the converted signals, by using an installed cable encompassing G.652, G.653 and G.655 fibres, and also polarization insensitive conversion by using a counterpropagating loop configuration.
