Moreover FWM crosstalk will be very high in this HNLF so even output will not give u clear eye diagram. if u r using more than one channels increase the channel spacing to more than 100GHz. I hope it works.
Yes agreed with Dhiman signal proagation in hNLF takes unusually long times i have been working on it and worst is when results are not as expected and we need to make further changes.
My advise : decrease launching power, decrease sequence length and length of HNLF . With such small dimensions kindly make HNLF of few tens of nts pssbly 50-200 m
Hello sir i am not aware of using bidirectional fiber but using SMF and changing its parameters to be used as HNLF both show FWM generated idlers. u kindly check th ZDWL ie Zero dispersion wavelength settings.pump wavelengths shpuld be around that moreover bidrectional fiber may lead to pump signal propagation in opposite direction. kindly check this
and then finding this decreased appreciation we feel less motivated to be on this platform… agreed
Yes sam right i also observed this earning points has become relatively difficult which obviously is demotivating. we all who are engaged in researcg are obviously time bound and its only limited time we get to exchange information here
i have designed 100 channel DWDM system on similar lines
Choose WDM transmitter.. open its properties box set its channel to 80 then choose starting frequency and the channel spacing. Set the input power as well. in next tab set RZ or NRZ format and bit rate too . then u choose WDM Mux set its channels to 80 and in next tab individual u define te channel frequencies. the output of the this Mux is given to the transmission fiber. u may set its dispersion characteristics if needed
.. try this
actually the system i have designed may not be of much help to u coz i am not using EDFAs in my design
Hi sahil i have just seen the paper u r following for implementation and feel its quiet easy to implement in optisystem. it has sown the complete design rather. i suggest u try it and optimize the parameters still if u r unable to find the problem share it with me ….i am quiet sure i will be able to solve it
u can also print file as .bmp from same blue icon. this file can then be converted to any format
As if current design is concerned output is fine all receiver with same parameters same frequency…how can they detect different signals
Hi vishal i just checked ur design could upls share the base paper u r following because i perceive ur design needs tuning of parameters to receive the signal. I would like to have understanding of how multiplexing is created before we change parameters or connections
Hi Damian i have done work on 40 Gbps RZ DWDM systems… but i wanted to know what is differenece between optisystem realization of free space comm DWDM system and DWDM system we implement using a fixed length tranmission fiber, amplifier and detector
hi sam i have another query regarding BER… if suppose my BER analyzer is showing BER well below 10^-9 but using OSNR values measured by dual port WDM analyzer i get very gppd BER of the order of 10^-30 ..using the empirical formula. what BER values are right… is it okay if i give my results according to WDM analyzer calculated BER for a WDM system.
in the meantime i too will try and increase channel spacing upto 50 Ghz and chevk…
