Modern Fiber Optic Communication Systems Simulations with Advanced Level Matlab Modules
(1) Use the Existing Modules / Components for Your Research Papers, Research Projects, Theses and Lab Simulation Experiments.
(2) Modify the Modules / Components to the Next Level for Your Research Papers, Research Projects and Theses.
(3) Integrate Different Modules / Components in the OCSim Package to Realize Your Own Fiber Optic Communication Systems.
(4) Modify the Modules for Co-Simulations with the Third Party Commercial Optical Communication Systems Softwares.
NRZ-PSK transmitter that uses dual drive Mach-Zehnder modulator (MZM) is simulated. The MZM is driven by polar NRZ signal The pulse shape is assumed to be raised-cosine.
This Module calls the following Sub Modules and Components:
Calculates the average optical power in dBm units
Modulates the output of the laser with PSK data using a dual drive Mach-Zehnder modulator
Plots the eye diagram of the optical power.
Explore Further this Module:
4b.1 Modify the source code by changing the roll-off factor, alpha from 0 to 0.9 with a step of 0.1 and plot the time diagram, eye diagram and spectrum.
4b.2 Change the variances of transmitter electronic noise and optical noise and observe how the eye diagram provides the visual information about the noise. Also observe how the noise floor in the spectrum increases as optical and/or electronic noise variance increases.
