DESIGN OF DWDM NETWORK
- Slide 2
- Background DWDM is multiplexing technology in fiber optic used
occasionally for long distance data transmission. Needed simulation
to find total losses that got in DWDM transmission. Needed
simulation to make easy calculation amplifier in DWDM.
- Slide 3
- Scope of The Research The problems that be discussed is limited
to design simulation power budget to calculate the total losses and
number of amplifiers required by DWDM transmission using GUI MATLAB
program.
- Slide 4
- Research Objectives To facilitate calculate total losses in
transmission lines. To facilitate calculate number of amplifiers
needed in transmission line. To prove the best parameter in DWDM
transmission.
- Slide 5
- Methodology of The Research Study literature. Design simulation
with program MATLAB based on GUI. Coding process to produce
appropriate simulation with purpose. Final step is testing
simulation that has made.

- CONCLUSIONS This program simulation can be used to facilitate
calculating the value of power budget that will be generated.
Results of the simulation are same to the mathematics calculation.
DWDM better use wavelength 1550nm and amplifier EDFA because has a
small attenuation and gain of EDFA bigger than gain Raman
amplifier. According to existing theory, transmission long haul APD
better than PIN because has a great sensitivities and can
accommodate the wider bandwidth.

- Suggestion To generate a simulation that much more complete and
accurate to the real condition, it would require a more
comprehensive type of parameters and has a predetermined value by
the IEEE or ITU-T.
