Setting Up EDFA Analysis Parameters
4. Enter values in the boxes as explained below:
Start range (nm or THz): starting range of the channel list.
Stop range (nm or Thz): ending range of the channel list.
Channel center wavelength/frequency: spectral center-of-mass for
the peak in that channel.
Note: When using the custom channel center wavelength option, the first channel
will be centered at the start range, and the list will be created using channel
distance and channel width.
Channel distance (nm or GHz): distance between the channels.
The value of channel distance will be set depending on the
selection made for the channel center wavelength option. The
channel distance box will be enabled only when the channel
center wavelength option is set to custom.
Channel width (nm or GHz): limit inside which the power values
will be considered in the channel. Integrated power is calculated
on channel width.
