Hi Heitor Galvao
Where is the DCF component in optiwave library ?
Thanks in advance

i recommend this course for you also Fiber Optic Communication – Agrawal 4th edition

Hi Damian
i used white light, but i have a problem in the first WDM mux .
range of wavelength used 1550–1557.8 with .8 spectral width.
which bessel filter center frequency and bandwidth for white light is appropriate.
Thanks in advance.

Hi Damian
what i mean when i made sweep range and try to draw it Vs. BER the first run result is the blue line ,when i made a second run for the same setting the red line produced. how can i reduce this so much change in results ?
can you please answer my question in the fourth replay
Thanks Damian very much.

when i make sweep range every time i run the project the BER result is different .(different graphs (BER VS. range) ) ? how can i realize the appropriate system result ?

can you check if the bessel filter center frequency and bandwidth is appropriate.
Thanks in advance.

Hi Damian
i want to clarify the following points to me
1- how you increased the power dramatically for the White Light source.
2- how you determine the appropriate center frequency and band with (Bessel filter) for the project.
3-is there any simulation examples for using MIMO technique
sorry for many questions but i need to understand
Thanks in advance

Hi Damian
i can’t figure where is the different in frequency between first 1:12 WDM Demux and first 3:1 WDM MUx
Frequency[0] 1555.6
Frequency[1] 1556.2 in first WDM Demux
Frequency[2] 1557.8
in WDM MUX Frequency[0] 1555.6
Frequency[1] 1556.2
Frequency[2] 1557.8
the same thing at receiver side.

Hi Damian
i tried to change the sample rate in global mode but its close. also i changed the sample rate in white light to 2.5 Thz but it didn’t work.
can you tell me how you calculate the bandwidth ?
Do you mean changing the center frequency of PIN photo-detector ?
also i change the band with in LED to 2.5 THZ but it didn’t work .
if you tried and worked with you please attach the modification.
Thanks in advance

hi Damian
i used white light source but it didn’t work as attached. can you check it ?
in my project i use spectral width between each channel equal to .8 nm and i need 20 channel , i tried to increase the bandwidth of LED transmitter to 16 nm but it didn’t work.
thanks in advance

Hi jaffar
Thanks for your help.
but i have a problem in drawing when i try to drag object to the 2D graph X-axis. its closed like in atttached image
Can you tell me how i can do that using matlab ?
Thanks in advance
