Abstract :
Improved all-optical noise suppression capability is demonstrated using concatenated nonlinear optical loop interferometers with highly-nonlinear dispersion-shifted fibre. Reshaping characteristics are significantly improved by the use of a two-stage configuration and a noise suppression capability of ~6 dB is obtained
