Abstract
A ferrule for an evanescence field sensor line is specified that has a lower part and a correspondingly attachable upper part. The upper and lower parts respectively have a recess substantially in the shape of a half shell in such a way that in the assembled state a guide tube is formed for holding an optical wavelength in a fashion enclosing the end face. A number of geometric structures for locally fixing the optical wavelength are respectively arranged in the recesses. Furthermore, a pressure sensor having such a ferrule is specified that contains an optical wavelength configured for pressure acquisition by influencing the assigned evanescence field, and at least one optoelectronic module. The ferrule is assigned to the optoelectronic module.
