can you please suggest me some simple way to implement channel impairment technique like DBP or optical phase conjugation using optisystem 13 version only.
can any one suggest best possible modulation technique supported by OFDM based WDM RoF systems?

Please can you suggest me some preferable values of BER and EVM for WDM OFDM based ROF system up to 1000 to 2500 Km channel span?
suggest me good reference if you can please…

Hi,
If I use this for designing Optical Interconnect in a Data Center, can I get the output of the Throughput and Power Consumption in the Designed System ?

Hello, i want to know what is my problem on my simulation, it is a WDM system with fiber simplemode, and i can`t understand why in my OSNR results doesn´t have so much diferent between using 100km of fiber and 30km of fiber, maybe my parameters aren´t corrects, i dont know exactly, i am new on this program, and sorry for my terrible english.

Hi shahid, i was see your simulation about “TWDM Symetric with SOA”, but i’m still don’t get it why you must using “dynamic Y select” at the upstream side.. could you help me to give explanation about it? Thanks

What will happened to the amplification and noise properties of the WDM channels if EDFA is used simultaneously to amplify multiple WDM channnels span over the gain wavelength range of the EDFA

Hallo
Now, I am doing project using optisystem
I make a dwdm using raman amplifier..
but when i calculate, i stuck and said “error calculated raman amplifier..
anyone can help please ….

Hei guys, please tell me what application is used to make a signal path like video optisystem dwdm??
Thanking in anticipation..

Hi,

I’m trying to use this component of Optisystem 13.03 to grab some Gain results of my EDFA. I’m using the sweep mode to analyze various parameters but when I put the results on the report page they’re all zero. I’m using Windows 7 Ultimate 64 bits and running Optisystem 13.03 with the token access of my lab. What can I do in this case?

i have designed 100 channel DWDM system on similar lines

[gaganpreet KaurParticipant]

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

Hii damian Can u tell me how to design an 80 channel Dwdm system. It would be great help if u send me the osd file of 80 channel dwdm system

Hi

we can use two kinds of visualizer for measuring noise power: WDM visualizer and optical power meter.
However, in my simulation, the results of two visualizers are different?!
What is the reason??

Hello khadraoui souleymen,

Do you resolved issue with Coherent Detection WDM Optical OFDM System?

hii Damian i am working on a DWDM system and not able to get the exact results that are mentioned in the paper. please help. I am attaching the osd file as well ass that paper on which i am working.
