Need Help

Hi sayed
Your system is working properly and all the parameters are set correctly.Only thing you have to do is set the FBG BW around 20THz and change the center freq. of FBG to 193.1.You were getting the results on only that channels which were in 1THz of BW from your FBG selected center freq.Try it and you will desired results.I will attach file,once you try it by your own.

Hi sayed
In general bandwidth of FBG is three times the bit rate.But this is only when you are using single wavelength for transmission.Fbg simply reflect that wavelength according to the grating spacing fixed by you.As you are using 16 wavelengths with 100GHz channel spacing ,you have to set the FBG BW more .But i am not sure about 20THz ,because this BW is excessively large.Basic idea is you can use BW in which all your channels come.There are no hard and fast rules to select frequency equal to 193.1,you can select other too.

Hi Sayed
Abhishek explained well,But i would like to correct the answer on FBG bandwidth.As Abhishek said BW is 20THz ,but this value of B.W is really large .Better then this you can follow simply this method
If you spacing between channels is 200GHz and 16 channels then

A rough calculation would be
200GHzx16=3200GHz=3.2THz
So according to me 3.2THz BandWidth would be sufficient for Fiber Bragg grating in this system.Try it and see the results whether system work or not.

Please attach your file.

Hi sayed,I am not able to find your file,will you please attach again

Hi All,

We are noticing some issues with attaching files and are working to get his fixed. It doesn’t seem to happen all of the time, but it definitely is causing a problem in this topic.
