WDM with Matlab Component

Hi,

When signals are combined in Ideal Muxs or Power Combiner, OptiSystem will sometimes automatically merge the channels into one signal, with the average carrier frequency. This is normally because the channels are very close in frequency and it makes more computational sense to only have one signal/channel. Of course you can retrieve individual channels by using a rectangular filter.

Cheers

I get a different number of samples than you. After the Ideal Mux the Matlab component contains a sampled signal of 2097152 and before each sampled signal is 1048576. The output of the Ideal Mux is then twice the number of samples of the input, yet containing 5 channels.

The sampled signal is twice the original the sample rate of the individual channels because although there is some overlap of the signals the resulting signal needs to represent a larger bandwidth signal and thus needs to have a larger sample rate to span the spectrum.

The sampled signal is centered at the average between the input wavelengths and contains all of the sampled information.

Regards
