Today I am going to report progress of our Tubes :
Here, we will simulate the relative basic optical fiber
communication experiment using the basic OptiSystem
models and then presents the simulation results.
A. Simulation of wavelength division multiplexing
experiment
WDM (Wavelength Division Multiplexing, WDM) is
an important progress in the development history of optical
fiber communication technology. The basic principle
of the WDM is that the light signals with different wavelengths
is put together at first, and then coupled to fiber
optic cable lines in the same fibers for transmission. At
last the receiver separates the different wavelengths by
signal processing, restores the original signal and sends
them to different terminal.
According to Figure 1, the related modules of the system
are transferred in OptiSystem, then consists a system
diagram, shown in Figure 2. The system consists of laser,
wavelength division multiplexing, optical, demultiplexer
and optical spectrum analyzers and other devices integral.
We set the light source composed of four lasers with
emission frequency 193.1THz, 193.4 THz, 193.7 THz,
and 194.0 THz respectively. The light signals from the
four lasers are put together through the WDM combine,
and then coupled into the optical fiber. At last, the signal
wavelength demultiplexer separates the combined signal
in the terminal which is represented by optical spectrum
analyzer.
The progress still do not MATCHED as it should to be , we are trying to optimum it.
