Hello Jyoti,
Firstly I can’t see the screenshot you have uploaded. Kindly, upload it again as it is not visible. Secondly, i suggest you to upload the osd file so that people could check what you are basically doing wrong or what is wrong with your design that your error rate is so high due to which your eye diagram is all over the place. For now, i suggest you to decrease the data rate which i think may be too high. Also try to increase power a bit and also check other parameters like global symbol rate which should be higher than the bit rate. I hope you find it helpful.

HI JYOTI
aabid is right ur snapshot of the eye diagram is not posted…plz upload it again as it is not visible..
u must upload your osd file because it will be more convenient that way only…maybe we could rectify the errors you are making..You can work upon the suggestions provided by aabid in the above comment and see how your circuit works…and i hope your results will improve but try uploading the osd file..
thanks and regards

Hello jyoti,
No need to worry. It is just about format of the photo you are uploading. It may be other format than jpeg or png. Try converting it to jpeg or png if not so. It will get uploaded for sure. I had also faced such issues initially.

HI JYOTI
try doing what aabid suggested maybe it will help you…i think he’s right that maybe the issue with uploading files atleast with the photo if not with the osd file..Try doing it and try uploading it again and i hope it will get your issue resolved.
Thanks & regards

HI JYOTI
I just checked osd file of your’s…You have basically created some sort od add/drop block and instead of using the BER analyzer you might use optical spectrum analyzer to view the waveforms of the signals on each side of the so created module…which in my opinion is the right thing to do because what i understand here is that you are adding and removing a particular frequency which can be visualized rather than measured…but u can decide because u know the applications..i hope wil be helpful.
Thanks & regards

[jyoti rainaSpectator]

hello fayiqa mam.. tahnx a lot i appreciate ur replying to my query..i think u are very right and i instead should use spectrum analyzer..i am new to this tool so i thought i hv to use BER analyzer bt u hv given me a good suggestion of using the spectrum analyzer whcih i shud use to view my optical channel..thanx agn

Hi Jyoti Raina

the osd file you have uploaded is blank its not showing any design or model. i believe there is some problem. Fayiqa Naqshbandi can u please tell me what you saw in the .osd file it totally blank.

hi sahil singh…are u also not able to open the simulation file….?
its quite strange…now i hv attached the file and kindly check it..i hope u wil be able to open it this time..thanx agn

[Aabid BabaParticipant]

Hello everyone,
I can’t tell if the file uploaded by jyoti does open or not as i do not have access to the tool right now. Fayiqa has been able to open it while Burhan num you are not able to access it and if i could understand from the error message it has something to do with privacy of the file. May be jyoti has locked it or something like that because in that case i guess this error should pop up.
Regards

[jyoti rainaSpectator]

hi sir…i hv not locked the simualtion file..i dont know what happening..there was error in uploading..shall i upload it once again if u people want..okay i ll attach the file again and i hope this time all will open it and help..thanx to ol

Hello jyoti,
As i mentioned that i don’t have access to the tool currently so i cannot open your .osd file anyways. Shall try accessing it tomorrow only. I hope other members will help you and i believe what fayiqa has mentioned is the way to go if you are implementing such system. I had also worked on add/drop modules the same way as she has mentioned. i hope you find it helpful.
Regards

[jyoti rainaSpectator]

hi aabid sir n burhan sir…as i mentioned earlier that i hv not locked the file…it was security error first…i hope u all arenw able to open and access the file dat i have uploaded… plz if possible try to rectify the mistakes i might hv done..and i hv already taken suggestions frm fayiqa mam..i ll try using spectrum for result analysis rather using BER analyzer…thanx all 4 ur suggestions….

[Aabid BabaParticipant]

you are welcome jyoti.

[burhan num mina llahParticipant]

Hello Jyoti raina

Yeah i agree with aabid saying that there might be some lock issue , but since u have uploaded it again i ll take a look at it as soon as i get access to license. Sorry for the delay but you migt have to wait till tomorrow. If i found to open it and know anything about you issues i would certainly try to help.

Regards

Burhan
