In a method for measuring relevant parameters of individual fibers of single-mode and multimode fibers of glass- or plastic-fiber cables, measuring radiation is reflected at the end of the test fiber to the fiber input by a mirror, particularly a Schmidt mirror having very high reflectivity (>99%), the measurement being carried out at the coupling-in site by a combined transmitting and receiving device. The Schmidt mirror is connected to the test fiber via a so-called fiber connector. The highly reflective mirror coating is applied to the end face of a given connector, so that the Schmidt connector provided with the mirror coating is connected to the test fiber either directly or via a short glass-fiber cable piece terminated with a standard connector and with the Schmidt mirror connector. With the use of a glass-fiber cable piece thus terminated the Schmidt mirror connector remains untouched and is protected.
