Complete experiment system for quantitative investigation of transmission of signals via optical media, plus the processes of optical multiplexing and de-multiplexing. To build a two-dimensional optical system of high precision, a magnetic bench with a printed grid is provided, upon which it is possible to write.

Experiment topics:

• Glass fibers and optical telecommunications
• Acceptance cone and optimization of coupling to a fiber optic cable
• Absorption, effect of the length of the transmission line
• Coupling losses
• Diffraction by an optical grating and optical multiplexing
• Dichroic filters and optical de-multiplexing
• Spectral composition of light sources
• Spectral dispersion and recomposition
• Color and interference filters
