    I tried above system.
    but Actually while implementing SAC-OCDMA with MD code
    e.g if I consider 5 users with code weight 2
    code will be U1= 1 0 0 0 0 0 0 0 0 1 U2 = 0 1 0 0 0 0 0 0 1 0 U3= 0 0 1 0 0 0 0 1 0 0 … U4 and so U5.
    Now I am allocating wavelength = U1 = 1550.1 and 1551 U2= 1550.2 and 1550.9 …spacing of 0.1 nm for each wavelength for users.
    at receiver end I am using same grating value to detect signal using direct detection. But I can’t. And I even tried to change power levels and also sample rate.

    Can i get solution for same?

    Dear Ahmad Atieh,

    Thank You for gentle response. I will surely go through those sample systems.

    I am using OptiSystem vesion 15.
    the problem I am facing with designing system are:
    1) How to simulate for higher users 2) how to get constant (almost near around range) BER e.g.e-14, e-13, e-15 For all active users. Currently I am getting large variation in BER for each receiving users.
    I have attached file for same here named md_5use2W

    When I try to go for White light the system doesn’t work. File for same I have attached named as DD SAC.

    Can you please point out my mistakes to overcome above problems and suggest probable changes?

    Hoping for quick gentle response
