POWER Budget

[Mohammed Ahmed Alaydi]

Hello All,
I am designing a WDM-PON network and i want to draw a 2D graph with “Power budget” as x-axis and “Log BER” as y-axis, but i do not know how to get Power budget on the graph. waiting for your help ?

I’m not sure what “Power Budget” means. Are you interested in the total power used by every active component e.g. Laser output powers?

[Mohammed Ahmed Alaydi]

I mean Link Power budget , that is ” transmitted power – receiver sensitivity “

[Damian Marek]

Ok got it! I believe I answered part of your question in another forum post:

System Power Penalty and Link Margin

There is also a tutorial example on calculating the receiver sensitivity:

Receiver sensitivity—Minimum input power (Optical System)

There is not a variable that is automatically created by OptiSystem that describes the Link Power budget. You could create one by using the Optical Subtractor component and then using an Optical Power Meter. Then using the result of the power meter as the variable on the y axis of your graph. Are you sweeping the transmitted power and/or the receiver sensitivity?

Thank you Mr Damian for Help, I sweep transmitted power. I Will try the solution you explained in your post.

Hi Mohammed,
Use excel to draw the required graph.
I think excel is easy to use.
We could change the type of axis like lagarithmic, decimal and others.
So, you can plot using excel.
Go through following links.

Thanks,

Hi
what is the procedure to calculate power budget?
