Operation Margins of 40Gbit/s SOA-MZI Used in Differential Scheme for Optical 3R Regeneration

Operation margins of SOA-MZI used in differential scheme are measured at 40Gbit/s for input signal wavelength and pulse width. When implemented in series in an Optical 3R Regenerator structure, compatibility with NRZ data and tolerance to input wavelength up 6 nm are demonstrated.
