hi aabid baba,
add module,……………..Adds a WDM channel and a WDM signal
technical back ground
The input signals are filtered by an optical filter and are combined in one signal. The first signal is filtered by an inverse filter. The optical filters can be a Rectangle, Gaussian, or Bessel optical filter.
Defining crosstalk
The level of crosstalk for both MUX and DEMUX components, is defined by bandwidth, ripple, and depth of the filter. These 3 factors will determine how much power, from neighboring channels, will act as crosstalk terms when calculating the performance of a specific channel. The most important parameter is depth, as it will play the most significant role in determining the power levels of the neighboring channels.
