hello Mohammed Abouseif,
Thank you for your reply…I got a clarity now on this.
Also, do you know any challenges faced by UDWDM PON system so that I can focus my research more toward that way and thus I can save time. I am working on it past 3 months but couldn’t find any challenge to work on it. Please just let me know if any. It would be of great help for me.
Thank you
MD TAUFEEQ AHMED
