Набор для изучения связи по оптическим каналам
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
