    Hi Ranjeet Kumar,
    Your osd file attached is 8 channel RZ wdm system and not CSRZ. please check it again and let me know if I’m wrong.

    Thanks

    Hi SAHIL SINGH,
    I got this from some simulations that I have done before , but I would also know if there is any theoric explanations about that.

    Regards.

    Hi Naazira Badar and FAYIQA NAQSHBANDI,

    the problem is not increase or decrease the wdm bandwidth for getting better results (no rule for that). From some of my experiences, this variation depends on the modulation scheme used and also the length of the fiber…

    with Regards

    Hi Fayiqa,
    Here i’M attaching the paper, please read it and tell me what’s his point here the fact that he is comparing the behavior of some modulation formats with the use of different Amplifiers. I can’t see any contribution here (My opinion).and I couldn’t get the same results
    Looking forward for answers

    Thanks & Regards,

    Hi Aasif ,
    Much Thank for all those Information.I’m using those Amplifiers at the end of the link. and just wanna ask if Anyone knows whether there is a difference in term of EYE DIAGRAM of some modulation formats like (CSRZ, DRZ, MDRZ, RZ,…) or not

    With Regards

    HI Fayiqa,
    Thanks for your suggestions. Actually I have seen a paper and it mentions that the bandwidth of wdm multiplexer depends of the modulation format inserted and the bit rate. furthermore, it sets the bandwidth for a bit rate 4*10 gbit/s (4 channels) like
    -for RZ modulation B=4*bitrate
    -for NRZ modulation B=2*bitrate
    -for CSRZ,DRZ and MDRZ B=16GHZ
    My question is how does he get this ??
    I did the same simulation but I got bad eye diagram in the case of RZ and CSRZ.

    Hi FAYIQA,

    yep I’m using optisystem 14, and it just has the N*N AWG

    Hi FAYIQA NAQSHBANDI,
    much Thanks for your help and participation, Your system works perfectly, but it seems like the system That i want to design is much more complicated. any one know how to design the 1*8 AWG ?
