Ng Pon 2 Simulation

[Nguyen Hai Ha]

Hi every one
That’s my honor to receive your helping about my problem, especially, all of you had very well knowledge about optical network system. At present, im doing my thesis about Analysis of performances of (NG-PON2) for FTTH systems: Performance on single channel transmission. I based on attached document

But they using VPI and i cant use and buy this software. Im trying work with Optisystem 7 and download some of your .osd in this topic: https://optiwave.com/forums/topic/twdm-pon/
Could you please kindly suggest me a Twdm POn osd file same my document

And how can i show this diagram by using optisystem 7

hope to receive your comment, thanks a lot your reading

hi nguyan hai ha,

i am attaching the all sample pon—realted .osd files from my optisytem 14 ….but i think it will only help you if you are using optisystem 14…because optisytem is not forward compatible.

[Nguyen Hai Ha]

Hi aasif, i still only designed Gpon before, thank a lot your attach files, do you have similar TWDM system like my attached file?Thanks

[Aabid Baba]

Hello Nguyen,
Why do you need a TWDM ?
Regards

[aasif bashir dar]

hi all,
i think she needs to NGPON2 archtecture ,which makes the useof optical time division wavelength multiplexing..
i suggest nguyan hai ha to go these links;

1.https://optiwave.com/resources/applications-resources/optical-system-time-division-multiplexing-tdm/

2.https://optiwave.com/resources/applications-resources/optical-system-optical-time-domain-multiplexing-otdm-design/

3.https://optiwave.com/forums/topic/otdm/

hope these might help

with regards

Hi aabid and aasif, thank for your comment as i said i try to do analyse Performance on single channel transmission of ng pon2 with some impairment: antenuation, Cd, non linear,…base on my attached file, in my attached file, they use 40gb upstream( 4 pair wavelenght 10gbps) and 10gb downstreem. But i still want to build a TWDM 10gbps upstream(4×2.5gbps) and 2.5 gbps downstream, in addition, i dont know how to use optisystem to show diagram same figure 27 in my attached file.

hi nguyan hai ha,

are you taking about the attached figure;;

with regards

[Atul Sharma]

Hi . Greetings!
I guess she is talking about the same but let her respond first.

[Nguyen Hai Ha]

Hi aasif, that’s right, how can i use Optisystem to show the same dỉagram?

[Ranjeet Kumar]

Hi hi nguyan hai ha,
I am uploading different networks design of wdm system with different advanced modulation formats, advanced modulation formats like CSRZ, DRZ and MDRRZ are spectrially efficient and require less power and also used could transmit upto even longer distance.
You can change different parameters like laser power, fiber loops, global data rate , channel spacing and other parameters to see variations in BER and Q-factor and design as per your choice.
Hope this will help you.
We know the latest version is hybrid of TDM and WDM system .
so, i think this to share .

[Ranjeet Kumar]

Hi hi nguyan hai ha,
Due to problem in internet connectivity, i am unable to upload the files being discussed above.
I will try to upload the files one by one or simultaneously.

Hope this will help you.

[aasif bashir dar]

hi,

yes you can definitelly optain such graph in optisytem.. kindly follow the steps below;;;

1.first fix the CW laser power to 3dBm.
2.provide the sweep to length of the fiber and enter the values for the length as 0,20,40,60,80,100 (this means no. of iterations is 6).
3. after simulation of your design,,,open the report of simulation…obtain the opti2Dgraph of BER vs the your sweepsi.e length….this will be the graph at txpower 3dBm….
4. Export this graph (in pairwise ) in the text form,,,name it say BER@3dbm..

now change the tx.power and repeat the steps 2-4…

now you can use these text files, to form the graph in excel…

hope this helps

with regards

hi all , i think…
there is better explaination than the aasif sir has provided you….i appreciate his efforts
as i think that you are new to optisytem….i think that you fall in below problems…

how to provide sweeps????

Lesson 4: Parameter Sweeps — BER x Input Power

and how to plot graph in optisytem or opti 2Dgraph????

plotting graph

solution are provided in the linkss

now i think that your problem solved

with regards

Hi aasif, unmer and others kind guys, im so appreciate with your help, it very closed my deadline thesis, but i still only have a litle experience with GPON design. With diagram i know how to show I wil try your guide and let you know soon. But Do you have a TWDM osd same my attach file with 4×2.5gbps upstream and 2.5 upstream and can run by optisystem 7? Sorry for my foolish.

[Ranjeet Kumar]

Hi hi nguyan hai ha,
I am uploading osd file of TWDM PON for your use.
Try to simulate whether you could able able to simulate in optisystem 7.
Let me know after i will try to help you.

Seeking your response.

[Nguyen Hai Ha]

Hi Ranjeet, thank for your effort to help me. I try open by OS 7 but it was error: Fail to load document from storage, i will use higher version to open this. Thank a lot

[Nguyen Hai Ha]

Hi Ranjeet, althouhg i use OS 13, it still error: Fail to load document from storage, did your osd design by OS 14?

[Ranjeet Kumar]

Hi Nguyen Hai Ha,
Yeah, i am using optisystem version 14.
Okk , i will try to improve the system and will re upload the osd file using optisystem version 13.
I don’t think it has to do with the types of version, but i will see.

[Nguyen Hai Ha]

Hi ranjeet, i can open file by OS 14, thank for your effort to help me, pls feedback me on my fb

[Nguyen Hai Ha]

Hi ranjeet , wwhen i run the simulation your osd, it had error and stop working, can you help me?

[Rajguru M. Mohan]

Hi hi nguyan hai ha,
We couldn’t design hybrid TDM – WDM PON using optisystem 7.0.
You should upgrade your optisystem software version either 13.0 or 14.0.
Because previous version lacks some components.
In NGPON2 You can also use OFDM-WDM PON, Why are you to use hybrid TDM – WDM PON ?
Seeking your response.

[Rajguru M. Mohan]

Hi Nguyen Hai Ha,
These links are really important for NGPON2.
First we should have basic understanding of NGPON2 technologies and its standard parametrs.
So, I would suggest you to please refer to following links:
http://www.alticelabs.com/content/WP-Evolution-of-FTTH-Networks-for-NG-PON2.pdf
http://www.ieee1904.org/events/2015_02_joint_session/js_1502_fsan.pdf
http://www1.huawei.com/en/about-huawei/publications/communicate/hw-201329.htm

You should refer to various paper of IEEE standards about NGPON2.
Hope this will help you.

[Nguyen Hai Ha]

Hi all
thanks a lot your support, i tried to perform with attached file but the BER value not good follow ITU-T, could you guys please check it

[Rajguru M. Mohan]

Hi,
I have links which help you get more ideas about TWDM POn:

Hy all
I already make the TWDM PON simulation for my final project
pardon me, but can you help me to check if this network is wrong or not
hope to receive your comment

[Rupam Chakraborty]

Can someone please explain me this figure.
this the result that I am getting for NGPON2 system just before splitter
