Welcome Alisthu ,
I have already attached the file and a brief explanation is given with it about the system, however if you would like to know more then i will explain it. For now i can just explain it as:-
In this system a laser source externally modulated by MZM with data encoded by NRZ is fed to electro absorption modulator. A sine generator is used for the spectrum broadening causing cross absorption that is XAM. In second system EAM as a wavelength converter is same as we have described above , the only difference is i have used single laser source by not incorporating any data, rest you can see the system file i have given the annotations there. Thank You
