Educational content :

• Direct Laser diode intensity modulation
• Pockels Effect, linear electro-optic effect
• Light polarization, injection and transport of a signal in a fiber
• Optical fiber coupler study
• Multiplexing wavelength (WDM), demultiplexing, by a grating
• Demodulation, optical transmission of video and audio signals.

Educational content :

• multiplexing
• optical fiber
• injection
• attenuation
• transmission
• filters
• FFT
• crosstalk

The practical permits the study of a complete chain of optical telecommunication systems: the emission (modulated source with LED), the transmission (optical fiber), the reception (photodiodes) and two different systems of multiplexing and demultiplexing in wavelength (with diffraction gratings and dichroic filters).
