Hi Gede Teguh,
So, you have already said that you are trying to increase the bit rate and you are finding difficulties.
I suggest you to use advanced modulation formats like CSRZ, DRZ and MDRZ and DPSk because these supports both long haul transmission and high data rate.
As we know that The use of Dense Wavelength Division Multiplexing
WDM system is responding to the demands for high
data rate applications and reasonable mobility for broadband communication.
It is easy to see that the dispersion become
the major factor that restricts long distance fiberoptical
transfers as the bit rate increases . so, you must use dispersion compensation techniques to mitigate dispersion.
You should use Pre, post or symmetrical dispersion compensation techniques to achieve above goals.
dispersion
compensation is achieved with DCF using postcompensation.
Post -compensation scheme achieve
dispersion compensation by place the DCF after a
certain conventional single-mode fiber.. EDFA is
used to compensate the power loss generating by
SMF and the DCF signal. Three EDFAs are used in
the system as a power amplifier, inline amplifier and
preamplifier.

Hope it will works for you.
