I am working on a project of securing duobinary optical signal with optical chaotic signal. In the reference paper I used (pdf attached) the Q-factor of chaotic NRZ DB decreases as the length of the channel increases and setting the EDFA gain according to fiber length.
But In my project the Q-factor first decreases and then increases by increasing the channel length and setting EDFA gain as given in the reference paper. Help me out in this.
