Abstract

The invention provides a method and a device for, with a low bit error probability, repeating signals in an electro-optical network. The method comprises the following steps: receiving and converting of an optical signal to an electrical; inverting and/or application of a non-linearity on the electrical signal; converting of the electrical signal to an optical; and further transmitting of the optical signal.
