Abstract
An electro-optical modulator has a monomode light waveguide modulator for which a pressure-sensitive signal generator is provided as a signal source for the purpose of modulating a light power signal supplied to the monomode light waveguide modulator over an input light waveguide, the electrical output of the signal generator being either directly or indirectly connected to an electrical input of the monomode light waveguide modulator. The arrangement serves for the transmission of signals representing pressure values, for example, acoustic pressure values, over an optical transmission system, and inasmuch as the electrical signals are generated by the pressure-sensitive signal generator, no external supply devices whatsoever are required at the modulator for the electrical energy.
