Input power

[indayara]

Hello,

I created a topology with 3 nodes ( trx 1, connected in a roadm/fiber/trx 2; and trx2 connected in a roadm/fiber/trx 3).
I would like to apply differents input power for each transceivers. Trx1 working in 0 dbm Trx 2 working in -1 dBm Trx 3 working in 1 dBm. Is it possible?

Tks,

I'm not sure what you want to do but GNPy does not currently model impact of different input powers to a transceiver. Note that the (main) output from GNPy is OSNR/GSNR, which does not depend on transceiver input power. Also, as long as the transceiver input power is "high enough", the final BER normally does not depend on this input power. However, if the input power is close to the receiver sensitivity, it will have an impact on BER. This is sometimes modeled with an OSNR penalty but such a model is currently not implemented in GNPy.

Hi Jonas,

My network model each spans are projected to work in a specified power. For example a topology with 3 nodes and 2 spans. Connections: Node1-> ROADM1->fiber_80Km->Roadm2->Node2->Roadm3->fiber50Km->Roadm4->Node3 transmitting 40 channels between Node1 -> Node3 considering : -1dbm/channel between node1->node2 AND 0 dbm/channel between node2->node3.

With Gnpy I did : 40 channels between Node1 -> Node3 considering the same power in all spans However I' d like to transmit : 40 channels between Node1 -> Node3 considering -1dbm/channel between node1->node2 AND 0 dbm/channel between node2->node3.

Let me know if I can do it with Gnpy.

Thank you for your feedback.

It is possible to set different power in different spans by explicitly setting the gain of the EDFA in front of each span. If you could attach your topology json file I could try and help you with the necessary modifications.

Hi Jonas,

The files were attached (NetworkRaman_jonas.json and eqpt1_config.json) I added 2 news amps in eqpt1_config (EK_ILHCS and EK_ILHCS1). I wish set the following power out: Power out (edfa amps) for (POP Mnaheim to SM2 MOR Adelrsried) and (Wiener Neustadt to Hartberg): 15dBm; Power out for other amps:17dBm;

Thank you for your support.

Hmm, I don't see any attachment. Maybe github does not support attaching json files. Try to zip them or change extension to .txt.

@indayara , you'll have to visit GitHub's web interface and attach these files from there. E-mail attachments are not picked up on GitHub.

[indayara]

files in .txt.

First of all, the only way to have full control of the power levels in every span (as fas as I know) is to set "power_mode":false under Span in the equipment configuration file. Then you have to manually calculate and set the gain of each Edfa in the topology file to have the desired power out (depending on power in). You also have to make sure the resulting gain and power level are within the Edfa range specified in the equipment configuration file.

[Tobelightbeam]

hi @ojnas and @indayara , maybe we can do this in power mode through the "delta_p" of EDFA rather than target gain. In this way, the gain of a EDFA will be set according to the "delta_p" of EDFA and power_dbm of SI.

[ojnas]

@Tobelightbeam, you are right, thanks. Somehow I overlooked the possibility of setting delta_p manually in the topology file (it's not a well documented feature).

@indayara, this is probably the easiest way to achieve what you want. In this case you set "power_mode": true (as you already had in your eqpt config). The reference Edfa output power per channel is then defined by the "power_dbm" parameter under "SI" in the equipment configuration file (at least if you're running the gnpy-transmission-example script). For all the Edfas in the network that should use this reference power level you can either explicitly set "delta_p": 0 in the topology file or you can leave it as "delta_p": null if you also set "delta_power_range_db": [0,0,0] under "Span" in the equipment configuration file (I think you already had this). If you want an Edfa to have 2 dB lower output power than the reference you just set "delta_p": -2 in the topology file for this Edfa (the "gain_target" parameter for every Edfa in the topology file is overwritten in power_mode so you can remove it or leave it as is, it doesn't matter). Note however that the power will be "clamped" during propagation if the resulting total power is higher than the "p_max" for this Edfa type_variety specified in the equipment configuration file. So for example, for the Edfa in POP Mnaheim it could look something like this:

     {
      "uid": "edfa Pop Mnaheim",
      "metadata": {
        "location": {
          "city": "Pop Mnaheim",
          "region": "RLD",
          "latitude": 2.0,
          "longitude": 3.0
        }
      },
      "type": "Edfa",
      "type_variety": "EK_ILHCS1",
      "operational": {
         "delta_p": -2,
         "tilt_target": 0,
         "out_voa": 0
      }
    },

Yes, I think it should be possible but as for what Raman parameters to use, I'll refer the question to someone else. @AndreaDAmico, @aleFerrari?

[indayara]

Hi Jonas,

I don't have the Raman parameters. I'm trying to model my topology as in Fig attached. Roadm->raman ampl-> 120Km dual fiber - G655(30dB loss)-> edfa-.... In my gnpy model I used : RAman Fiber to connect the Roadm to edfa and in Raman Fiber I declared 120Km, but I don't know....

Thank you, Indayara.

Again, I don't see any attachment. Also, your message ended after "I don't know..." Did you mean to write what it is that you don't know?

Anyway, to simulate Raman amplification you need to supply the "raman_efficiency" parameter for the desired fiber type (G.655 in your case) in the eqpt config file. The default eqpt_config.json currently only includes the Raman efficiency for SSMF fiber type but there is an ongoing effort to obtain and include it also for other fiber types.

[indayara]

Hi Jonas,

Thank you for your reply!. I understood, it is ok!

[NeelamChahal03]

@ojnas HI Jonas,

I am in power mode = False and set the gain_target of Amplifier to control the Tx power at each Node, However I don't see delta_p is effective in power mode true.

This is what I want to achieve it using delta_p

Tx - In - 22.31 Out 12.00 Node A - Tx - 21.00 Rx Node B 12.23 Node B - Tx- 22.12 Rx Node C 12.32

and So on .

Is there a way to achieve it ?

[ojnas]

@NeelamChahal03, maybe start a new thread with your issue.

Tx - In - 22.31 Out 12.00

It's not clear to me what you mean by the above but it should be possible to achieve the power levels you want by setting the gain accordingly, as long as you're not limited by e.g. total amplifier output power.

[NeelamChahal03]

Thanks for the reply. I am using Raman along with Edfa. I observed the received power at next node is controlled only by pump power and fiber properties. However the transmitted power at every node is dependent on gain target. I am in power mode = false. When I tried to use delta_p in power mode true, I did not get the desired power at transmitter. Seems only gain target functionality is more transparent and provides required results.
