    Thank you for all , I agree with you in theory .. but in the optisystem program when use the length of DCF 24km , must the length of the SMF is 120 km .. Or SMF = 150 km must DCF =30 km , and so on .. Otherwise the the signal is distorted ..

    this my .osd file attached , i want to calculate the BER value .. in the BER Analyzer can show only the Eye diagram but the Q-factor and min. BER zero as shown in the image below attached.
    and want to calculate the OSNR

    thank you very much

    Thank you
    Did not show any result .. Only Eye diagram but the min BER and Q factor zero

    thank 🙂
    I applied all of this but did not show BER
    my system in this link
    https://drive.google.com/open?id=0B9H50S0Lc2YPYm1EQ0lJV2Jiajg

    Is it a way to link the BER Analyzer correct?
    why did not show !!

    I know , I have this DSP components implemented in matlab and I’m understand how linking between optisystem and matlab , but I want knowledge what modified to this DSP code to compensate PS QPSK

    alistu , DSP component in OPTISYSTEM for only QPSK , PM QPSK , QAM
    Not available for PS QPSK

    hi aasif , I have DSP Implemented in matlab With PM QPSK designed in optisystem
    I want to modified this DSP to make it compensate PS QPSK(implemented in optisystem)

    And thanks

    I want to compensate by using DSP ( compensate all Fibre Transmission Impairments )
    When increase the fiber length.
    I’m using DCF but this compensate only CD.
