Hello Shivam,
As I’ve explained to you in separate email. Due to the using of AMI coding, the signal bandwidth increased (almost doubled), which affected the signal quality after passing through 10GHz MUX/DEMUX. Thus the MUX/DEMUX filters bandwidth needs to be increased (40-50GHz). As a result of that effect, the 100GHz channels spacing caused also the signal quality to suffers from neighboring channel due to interference. Much better performance can be achieved if you use 200GHz channel spacing.
Regards,
Ahmad
