Hi all
I am trying to design a WDM system for 8 channels with 40GB/s for over 500 km .
My goal is to get a quality factor > 7 but I’m having only 5.2 .
So please share your knowledge and give me some help.
You can also find the attachment.
Thank you.
Hi Hamdi,
Here i have attached the modified file where I have increased the lasers power to 0dBm. I also changed linewidth to 0.1 MHz which is an acceptable value for low power lasers. I don’t know about the file you where loading dispersion data in dispersion compensating fiber, so I used “constant” option and entered the proper values. However, you can use your own settings if you want. The Q-factor is now more than 8.
Regards
Hi Alistu ,
Thanks, it works and the Q factor has reached even 10,great job.
I appreciate your taking the time to help me.
regards.
Hi Hamdi,
For low-power laser, linewidths up to a few kiloHertz can also be found according to wikipedia. However, the ampunt I mentioned for the linewidth was used in the paper “Transmission simulation of coherent optical OFDM signals in WDM systems” by Bao as a conventional value for commercially available lasers, and the references are given in the paper (even though they are not datasheet). I hope this helps.
Regards
