WDM MUX AND DEMUX BANDWIDTH

[GAYATHRI P V]

I have a doubt regarding the bandwidth of a WDM MUX with 4 channels.. By default the value for WDM MUX and DEMUX is 10 GHz. When I increased the bit rate from 10 to 40 Gbps for a simple WDM system , I got a distorted Eye Diagram . Should I increase the Bandwidth of WDM MUX to more than 10 GHz ?? Please Reply..

Hi Gayathri,
I think so, the wider the bandwidth is giving better results when you go up from 10 Gbps to 40 Gbps.

try it and let me know,

thanks

Sir, Please find the attached file. I have increased the bandwidth of WDM Mux in the system. Please verify the same.
