I am having problem in designing DWDM system with channel spacing of 25 GHZ or 50 GHZ.
I have designed DWDM system with 100GHZ channel spacing, but find no results when when i decrease Channel spacing to
25 GHZ. I have used symmetrical compensation technique with different advanced modulation formats MDRZ, CSRZ and DRZ.
Following parameters used are 40gbps bit rate, variable transmission length.
We use advanced modulation formats because CSRZ has narrow optical spectrum then the conventional RZ format
and high tolerance to group velocity dispersion (GVP) and mixed effect of self phase modulation (SPM).
DRZ transmitter of their optical modulation bandwidth DRZ format is very
attractive. It can be compressed to the data bit rate B that
is half- bandwidth of NRZ format 2B.
How could i reduce channel spacing.
Suggest me some ways so that i could get the expected results.
Here i am uploading the osd file of DRZ DWDM system.
Seeking your response.
