  • BER,Q-factro and OSNR of 200G/400G signal

    From sunil kumar@21:1/5 to All on Fri Feb 21 21:27:22 2020
    Hello Team,

    Can some one please explain what is the threshold value for BER,Q-factor and OSNR specially for 200G/400G signals and how can we figure out this.

    Thanks in advance.

    Regards,
    Sunil Kumar.

    I would expect to find in the specification of the equipment
    some graphs displaying the relation between BER, Q and OSNR.

    Best regards, Huub.
