Hello Damian,

Many thanks for your fast answer. Just one question, is not normal the users use the same wavelength to send data upstream?is not the standard? shouldnt ODelay prevent the signal mixing?

Thanks

Hello,

I think i had the wrong layout parameters(bit rate, etc). Now i think i am on the way, At least ONU BER looks normal.

But i still dont know what is happening with upstream in OLT, no data arrives there. do you know what can be worng?

(in attach the current layout)

Thanks in advance

Hello,

For the previous post by me i put a 1xN Splitter Bidirectionalthat i think is the appropriate one.

Now after i have done a very simple GPON layout(Not Raman amplification) when i run the project and when i check the BER analyzers it gaves a strange graph(i think is not normal). Do i have something wrong in the project?

Also in the upstream BER analyzer i cant see any data.

Project in attach

Thanks in advance

Hello Damian,

I am trying to make a simple simulation of a GPON and i found your GPON-Layout in previous post. I have made and found everything least the spliter. Can you please show me how to create it? Or do you have any layout done that you can send me to take a look on them?

Many thanks in advance

Ps: another thing, how to rotate the elements(like flip vertically)?
