Abstract: A measuring method for detecting a mechanical force acting on an object using a fiber optic sensor unit is disclosed. At least one measuring channel has a sensor fiber with a fiber Bragg grating embedded in the sensor fiber with a Bragg wavelength and a sensor detection element. The sensor fiber is fixed to the object in the area of the sensor FBG. The method includes coupling light from a light source into the sensor fiber and detecting the light reflected and/or transmitted by the sensor FBG by the sensor detection element. The light source has a wavelength-dependent intensity distribution with an edge. A wavelength change in the Bragg wavelength of the sensor FBG is determined by evaluating a measurement signal which has an intensity change in the detected light intensity of the entire light reflected by the sensor FBG and/or of the entire light transmitted by the sensor FBG.

Abstract: A fiber-optical connector system, including a fiber-optical connector and a coupling into which the connector can be inserted to establish an optical connection. The connector has a housing that extends along an axis and into which an optical fiber is arranged with the axis projecting with one end from the face of the housing. Means exist to cover the end of the optical fiber and protect the end of the optical fiber from any effects from the exterior when the connector is not inserted and to release the end of the optical fiber projecting from the housing when the connector is inserted in the coupling. A protection device for the connector system may be derived by configuring the cover means with a first cover element that protects the end of the optical fiber in the axial direction.

Abstract: The invention relates to a fiber-optical connector system, comprising a fiber-optical connector (10) and a coupling into which the connector (10) can be inserted to establish an optical connection. The connector (10) has a housing (11) that extends along an axis (49) and in which an optical fiber is arranged aligned with said axis (49) and projects with one end from the face of the housing (11). Means (30, 32) cover the end of the optical fiber and protect the end of the optical fiber from any effects from the exterior when the connector (10) is not inserted and release the end of the optical fiber projecting from the housing (11) when the connector (10) is inserted in the coupling (40). A reliable and space-saving cover and protection device for a connector system can be achieved by configuring the cover means (30, 32) with a first cover element (32) that protects the end of the optical fiber in the axial direction and that can be displaced at an angle to the axis (49).
