Dispersion Q factor range

Hi Abdikarim,

The effects of noise are present in various components like the optical fiber and amplifier. Because the noise has an element of randomness to it, that will cause some variation in your Q factor every time you simulate. As for checking the bit rate you can double click an empty area in the work-space and the layout parameters window will open up. In the layout parameters you can find and edit bit rate.

Best,

under default/amplifiers library/optical you can find the edfa amplifier. you will have to adjust the various properties to acheive a gain of 10db. If you press help you will find the equations that you will need to use. Solving Equation 1, Equation 2, and Equation 3 under stationary conditions allows you to determine the amplifier performance features. to make it simpler you can also use the edfa black box. the edfa black box allows you to simply choose the value of gain, power, etc instead of having to perform the calculations that would be required if you used the edfa.
