Abstract
There is provided a fiber-optic pressure sensor (110), which includes a waveguide (112) having an end, an optical deflection unit (301) connected to the end of the waveguide (112), and a sensor body (300) at which an optical resonator (302) is formed by way of a diaphragm (303). The waveguide (112) and/or the deflection unit (301) is/are attached to the sensor body (300) by way of a curable adhesive or a solder connection.
