Dear colleagues,

I am looking for the spectrograms (pictures) reflecting different phenomena, characteristics and features of operation of the DWDM networks for example: non-linear effects, non-uniformity of gain of optical amplifiers, non-uniformity of power of channels in a range, system loading more than 70 channels, a difference of width of a range for 10GE, 40GE and 100GE of channels and other interesting things.

I collect real pictures to teach our employees the analysis of spectrograms...

 

I hope that the company Huawei will agree to make a certain manual on the analysis of spectrograms for different practical cases? :)

 

 

Very interestingly. Thanks for sharing!

I spread examples of real spectrograms on a backbone network.

Somebody has examples of spectrograms with different non-linear effects and with unclear situations? Or simply interesting cases?

Thank you for sharing.

It is a good proposal

Once you collect those pictures please share us, they will be very useful.

Some  examples of spectrograms about eye pattern,

Good!!! Thank you for sharing!

Good example ,thanks !
