Optical fiber forms the backbone of the communication systems. The exponential increase in data traffic is putting an escalating pressure on fiber-optic networks. Optical fiber is an onlinear medium because its properties change with the signal intensity. It is well known that the fiber nonlinearity limits the achievable information rates of the conventional transmission methods in optical communication. The Fibre Optic Nonlinear Technologies (FONTE) is a European Marie Skłodowska-Curie Innovative Training Network (ITN) collaborative project. It consists of four academic partners:

and the industry partner Nokia Bell Labs in Stuttgart, Germany. The objective of the FONTE is to develop communication and coding methods suitable for the nonlinear optical fiber, in order to increase the data rates of the future communication systems. In particular, the project aims to apply nonlinear Fourier transforms to address the limitation that the fiber nonlinearity sets on transmission rates.
