Performance evaluation of a highly non-linear fibre based NOLM for regeneration up to 160 Gb/s

This work evaluates experimentally the performance of the first stage of the regenerator, which employs a highly non-linear fibre (HNLF), by investigating the suppression of the noise on the space at 60 and 160 Gb/s. The use of a highly non-linear fibre allows a large reduction of the required input power. The measurements show good noise suppression at moderate input powers.
