Description
Recommended

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
Signal shaping and matching
Band width and limiting frequency
Calculation of theoretical band width
Optical diaphony
