Hi All

Can anybody please suggest me the means by which i can check how fast my system is. is it simulation tym or actually we have some analyzer by which we can get what time does a signal take in going from transmitter to receiver side.

      Hi Burhan,

      The time it takes from signal to be transmitted in the system is highly dependent on the components used in the system, especially electrical components which may take more time to respond comparatively. To know exactly how long it may take, you must knwo the delay caused by the practical components.

      Hi Burhan.
      To see how fast your system is you need to analyze the delays associated with each component.
      Depending on the component and its theoretical model, some of the devices may or may not have an associated delay. Please refer to the link for further understanding.

      Hi All

      Alistu yeah i actually thought that there might be a component as such to calculate the delay of a system as a whole. But i believe now that we need to calculate it on individual component delay basis.
      Aabid yeah this link seems helpful and as u have rightly mentioned that there is no component as such to do that.But indeed there are methods to calculate the delay.

        hi Burhan num mina llah,
        You are welcome. I would suggest you to go for component delay analysis. Well, as far as your requirement is concerned, i think simulation time could play a role but right now i don’t know how but if you develop a relation between simulation time and the delay of the overall system , i guess it could help.

      Hi all..

      It is a nice query being posed by Burhan.

      Well I think if we try to relate the simulation time and the speed of network, it would be vague. It is because, if there are more no. of components in our system , the simulation time would be high.. but if these components are connected in parallel , no significant propagation delay can be attributed to these. I hope I have explained clearly.

      I think there is an option of propagation delay in components of the Optisystem. I’ll have to check that again before commenting further on this option.

      Regards.

        hi naazira,
        Well i think we have already discussed that more no of components does not necessarily mean more simulation time in the previous topic but yeah we may or may not relate simulation time with speed of network.Anyway , You mentioned of connecting components in parallel but i don’t think we actually can do it because of our requirements ( like we cannot connect fiber and amplifier in parallel and so on because it won’t serve our purpose there). There must be something which could help us in calculating speed of network but in one way or other it is related to delay associated with each component.
        Regards

      Hi All

      Aabid i believe Naazira is right in saying so because simulation time cannot be related to delay of overall system. Naazira i would like to know from u that how is possible to calculate this propagation delay. Is this parameter in the ccomponents itself or we have to attach some analyzer component in order get the delay of that component.

      Regards

        hi Burhan num mina llah,
        I too am not sure but as i said we might or might not be able to relate speed to simulation time. But as far as delay of components is concerned, i don’t think we have any delay calculating component in the component library. I guess you need to develop one.

        regards

      Hi Aabid

      I don’t think Naazira is trying to say that. I understood what she meant. She means to say that we cannot relate simulation time with number of components per se, because propagation delay in practical systems is increased by connecting the components in series and not just by increasing the number of components.

      Regards

        Yes burhan true that propagation delay does increase when connecting components in series but we don’t have an option here. So, delay will remain associated with our systems and would thus affect the speed of propagation.
        Anyway let us see how can be it possible to calculate delays.
        Thanks and regards

      Hi Aabid Baba

      yeah we need to search for means to calculate delays as Damian has rightly mentioned in that post, link odf which u mentioned abouve in your previous comment. He has given few methods to calculate delays and i feel so far we can try them to get our job done.
      Anyways thanks a lot.

        hi burhan num mina llah,
        you are welcome, always..!
        If we could calculate delays of components and somehow determine the speed of the network , it can really be a bonus to our research interests.
        I hope sooner than soon , we would be able to do it. Hopefully!
        Regards

    • #31684

      Hi Aabid Baba

      yeah that would really make much things simpler and save a lot of time and resources. As we would just have a component to calculate that for the whole of our system designs and models. I hope it comes sooner and make things better and lead to better optimization of resources. This is something in real demand. Hope!

        Yes burhan num mina llah,
        I feel a component should be in cooperated in the component library which could directly calculate delay associated with the component just like as power meters and WDM analyzers. Though problem remains about calculating overall speed of the network and it continue to remain so unless and until a mathematical model can be developed to do so. Hope somewhere down the line , we see it.
        regards

      Hi Aabid..

      Hope this problem is solved as soon as possible. Hope to see such component in the optisystem 14.1 which might come in few months.

        Hi burhan num mina llah,
        where did you read about this new version release?
        has optiwave updated it somewhere on their website..i would like to look at it.. please share the link if so.
        Thanking you in advance.
        best regards

      Hi Aabid and Burhan..
      Yes, I meant what Burhan has understood.
      And when I mentioned that I think there was an option in components to check the delay.. I was talking about the FSO channel. I checked it again. There is an option ‘propagation delay’..which lets take into consideration the delay between Transmitter and Receiver.
      I hope this gives an idea about what I was saying.

      Regards.

        hi naazira,
        Well I have also come across the delay propagation parameter shown in some of the components in the Optisystem component library but i guess it can be helpful only if we can be able to relate to overall propagation of the system design and moreover with the speed of the optical network. It is challenging but interesting and i hope somebody is able to do it.

      Yeah it definitely is.
      In fact it is one of my research interests and i really want it to implement using optisystem tool only.
