Hybrid Systems' examples

[RavilParticipant]

Dear support team,

Do we have any design examples of Hybrid Optical Transmission Systems (TDM-WDM) in OptiSystem 13?

[Damian MarekParticipant]

Hi Ravil,

Here is a forum post on the subject:

Designing a TDM-PON bidirectional system

In the samples folder the BPON Bidirectional example uses both TDM and WDM.

Olá Damian tem optisystem exemplos de novas aplicações de TDM WDM PON, referindo-se a “Divisão de tempo e de comprimento de onda multiplexados óptica rede passiva (PON-TWDM) para a próxima geração PON fase 2 (NG-PON1 e PON2-NG)”?

[RavilParticipant]

Dear Heitor, can you, please, briefly translate it in Eng if it’s related to my question?

[Heitor GalvaoParticipant]

are applications with the new access networks, which comes to meet the demand for bandwidth, the current TDM-PON systems are not able to supply that bandwidth, hence the need for migration for WDM-PON networks, but deploy networks WDM eh a cost expensive, so the need for Hybrid networks, if you search the literature specifies you will see the name, NGPON-1e NGPON-2

[RavilParticipant]

I see your point, but in my research I’m investigating Hybrid Optical Transmission Systems (HOTS) based on combination of TDM and WDM on the same network which allows to increase the capacity in one spectral channel.

[RavilParticipant]

But if you are considering TDM-PON and WDM-PON as separate systems, the last will always have higher capacity due to utilization of bigger bandwidth.

[Heitor GalvaoParticipant]

I agree at this point, but deploy networks WDM is an expensive cost, so the need for hybrid networks, do you have any book/article that might indicate?

[Heitor GalvaoParticipant]

Very nice this topic, I hadn’t seen this project BPON bidirectional

Ravil you own “bibliograficas references” that could indicate?

[RavilParticipant]

Thanks, I’ll take a look. You mean indicate Hybrid System deployment?

[Heitor GalvaoParticipant]

so, please check any study material that might indicate

[RavilParticipant]

If you considering cost, the main purpose Hybrid Systems is to reduce the number of spectral channels by increasing capacity in a single channel and, hence, reduce the number of components (filters, regenerators, etc.) required for these channels.

[Heitor GalvaoParticipant]

Ok Ravil

[RavilParticipant]

Thx for advice, it’s my area of research now which collaborates with super-channels and advanced modulation techniques.

[Heitor GalvaoParticipant]

Modulaçao OFDM for example?

[RavilParticipant]

There is no deployment of these systems yet. I can send you some experimental results after/if they got published.

[Heitor GalvaoParticipant]

See Ravil annex talks about NGPON-2, was wondering if team optiwave has files, on the line of this article

[Heitor GalvaoParticipant]

Yes I am interested if they are published

[RavilParticipant]

Yes, Co-OFDM is one of the methods. I’ll take a look at your and let you know in private message.

[RavilParticipant]

Can you also send me a description of the scheme you attached, pls?

[Heitor GalvaoParticipant]

Good evening, I’m in the process of Ravil research, to subsequently initiate an implementation

[Heitor GalvaoParticipant]

Will be welcome

[RavilParticipant]

Hi Heitor, do you mean you are working on a similar topic?

[Heitor GalvaoParticipant]

Yes, now I am seeking knowledge
