BER

Hello Khadija Omran…
BER has been throughly in one of the prevoius posts in the forum…here is the link attached…

BER analyzer

For more information on BER analysis kindly refer

BER Calculation Using the BER Test Set

How to plot BER versus OSNR

hope it helps to a great extend….

Hello Khadija Omran…

Kindly refer to the links posted by tanveer… This topic has been previously discussed in the forum… Also i again appreciate the efforts of Tanveer.. Thanks for the information

Hello Khadija Omran,
Actually, we calculate Minimum BER in optisystem using BER Analyzer which is found in electrical part of visualizer component library.
It is easy to find to Min. BER and Q-factor.
Here i upload an osd file
When you will double click on BER analyser, you will get value of Min. BER, Q-factor. You can get structure of eye diagram by just get tick on Show eye diagram tab in BER analyser window.

Hi Ranjeet,

Very nicely explained… Highly appreciate your efforts…

Thanks and Regards

Hello Khadija Omran,
I think i am right and i have attached the BER analyzer in right sense and i have got the results in BER analyzer.
I am uploading the jpeg image of screenshot of the results.
Please see the results of BER analyser.

Thank you Sahil Singh
For Your appreciation and regards for me. I will try my level best to get such appreciation.
I will try to help by designing some remarkable and appreciable design with efficiency and accuracy.

hello
very well explained by Raanjit and MHD NA….complete step by step procedure is provided by them…
hope you have got the problem solved now…

Hello khadija,
As rightly suggested by everyone how to visualize the results like in bit error rate ( BER ) and quality factor. Now the problem being that you are not able to get anything on the visualizer for BER and quality factor , well i suggest you to kindly upload the .osd file of your system design so that someone could help you.
Regards

Hello khadija omran

As far as i know .osd file can never be that big. And sorry i am having problems opening whatever you have uploaded.

Hello khadija,

Thanks for sharing the link…. It would be been more convenient if upload the .osd file so that everybody can analyse it so as to help you solve your problem… Try uploading it…

HI KHADIJA..
As suggested by few people you should try to upload your osd file…it is more convenient that way as already mentioned…The error could be because of various parameters and some errors for that matter…Try uploading the osd file…the problem u are solving will be solved if u are possible to upload ur file successfully…
Thanks and regards

HI KHADIJA..
Okay thanks for sharing your osd file.. right now i can’t access the tool sorry for that..shall try checking your system after few hours..hopefully to the extent i know this tool , i will try to set it right and hopefully provide you with a solution..Be patient..
Thanks & regards

Hi Khadiga Omran,

Thanks for sharing your .osd file… Will try to have a look as soon as possible…

Hi Khadija Omran

such results like Q.F =0 and Min. BER =1, this is always a very plain case of either your signal is not reaching the receiver; or that your system parameters are not getting supported by the system. Eg.your system design supports a maximum bit rate of 5Gbps and you are trying to simulate at the bit rate of say, 10 or 20 Gbps, so the results which you are getting can be easily expected.

You can connect visualisers at various points of your system to check the signal in its traversal path. In case the connection is okay, the there is definitely something wrong with the parameters you have taken.

hi all here
can u people plz tell me how can i make my results better..i am designing a simple four channel WDM system at 10 Gbps..my fiber lenght is 150km and transmitter power i hv taken as 10dBm..i get good quality factor around 25 bt BER is very high..
it s abt 0.345 e-012..i hv to get it close to 1.
Plz can u people tel me hw i reduce it..i wil grateful

Thank you Tanveer for your conscent and appreciation.
I will try my best to do some good works.
