Hello,
I am from Bangladesh. I am working with Crosstalk effect of CWDM technology. I am using Optisystem 7.0. Unfortunatly it was for trial version. I need licence key for using it. Can you pls help me regarding license key? I need more help to compare crosstalk effect of DWDM and CWDM. I will communicate with you later.

Thanks
Hayder

Dear all
I want to design WDM system with four channel with different data rate in the same system for example first one 2.5Gbps, second 10Gbps, third one 40Gbps and the last one 100Gbps. I already design it but when I change the data rate for any signal the other three change also i.e in case of changing the first one to 2.5Gbps all the remind channel change to 2.5Gbps and so on when changing any one the remind channel change also.
can you help me what to do to set every PRBS generator to own its data rate separately from the other

Dear Taiwo

i am simulating a UWB mono and doublet pulse generation system working at 10Gbps by using multiple optical signals.Two probes signals and one pump signal modulated by 10gbps data rate.then these multiple signals are interacting in a SOA under XPM and then at output of the SOA chirped pulse has been generated.When this chirped pulse is located at linear slope or quadrature slope of the WDM DEMUX transfer function,then UWB mono and doublet pulse generates.this is the scenario
rest of the problem is the same which i mentioned in the question.
i am also attaching the paper
Sir Taiwo,please look at the paper and try to solve my issue.
i will be very grateful for you
thanks
best regards

Hello brother. Your question would be more clearer if you can explain what you are trying to achieve by this setup. if it is a simple WDM system, all i know is that you would detect your signal by using the same wavelength used at the transmitter. Tell us what you are trying to achieve by coupling two different wavelength with a data carrying wavelength.

Thanks

Dear respected friends

Hope you all are fine

i would like to know the difference between

let consider we couple two probes located at 1549.15nm and 1549.24nm by using x-coupler at the TX end.At the reception side,we have to DEMUX these two channels by using 1×2 WDM DEMUX.If we click on DEMUX,then properties dialog box for DEMUX opens and in the channels tab,what value of the “nm” should be???Is it will be 1549.12 & 1549.24nm or any other?please explain?
i am very grateful to my friends on the forum for their great help.
i am also attaching the screen shot of the simulation
with best regards

hi everyone i am pursuing my researh on MITIGATION OF MOBILE OFDM RECEIVER USING ICI SELF-CANCELLATION SCHEME IN OPTICAL COMMUNICATION USING OPTISYSTEM i have tried and reproduced the results for 32*20Gbps WDM channel for different bandwidths like 100,200,300,400Hz. If i need to make a new system for 32*40Gbps my results are not up to the mark can anyone help me the steps i must follow to get the results?

HI all,

Appreciate if you can help me clarify my design. The simulation is successful but there is no result for OSA & BER Analyzer.

Thanks.

I attached a file in which I am getting good constellation of two channels but for other two channels I am not getting good constellation. Please help me

[deeksha bhandari]

Sir, I am working on WDM-OFDM system with 16-QAM and 32-QAM . The constellation diagram of 16-QAM has some phase shift and the output of 4 users are not similar as they should be. I am unable to decide subcarriers for 32-QAM as well . Please help me out.

i have simulated 8×1 channel WDM system upto MUX.when i run the simulation and want to see individual channel power and wavelength on optical spectrum analyzer and on WDM analyzer nothing graph or values appears.what is the problem and how to get values?

[shivakumar rjgrParticipant]

hi everyone, i have got the values of FWM in a wdm system and i want to check whether the obtained results are correct or not. please help me how to validate the results. i want to compare fwm of rz and nrz wdm systems

[Siddharth sharma]

Hi all, please help me to design Bi-directional WDM-PON system using RSOA in optisystem.
I am new to this software kindly help me with the osd file if anyone have for such system….
I would be extremely thankful and highly obliged.

hi everyone, i have calculated timing jitter values for one channel in a 16 channel wdm system using histogram from eye diagram analyzer. all i need to ask, is there any numerical approach to validate the result that we got from histogram of eye diagram analyzer

hello everyone,
i HAVE BEEN WORKING ON WDM SYSTEMS.I WANT TO MEASURE THE TIMING JITTER OF THE SYSTEM. PLEASE EXPLAIN TO MEASURE THE JITTER VALUE FROM EYE DIAGRAM. IN RESULTS OF BER ANALYSER, THERE IS A VALUE NAMED ” RMS JITTER AT USER DEFINED THRESHOLD”, COULD IT BE THE JITTER VALUE OF THE SYSTEM.PLEASE HELP
