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
