Effects of ASE on DPSK Modulation Formats with Different Duty-Ratio in Optical Transmission System

In optical networks, erbium-doped fiber amplifiers (EDFAs) are used to provide a wide and flat gain spectrum. Amplified Spontaneous Emission (ASE) emitted from EDFA adds to signal and grows rapidly. This accumulated ASE noise may limit the effective amplification due to saturation effect and affects...
