The invention relates to a method for the reflectometric testing of an optical transmission line from an optical transmission and reception device, in which a test signal is fed into the transmission line from the direction of the optical transmission and reception device and the signal reflected back to the optical transmission and reception device is analysed, in which the transmission device provided for transmitting the useful signal is also used as the transmitter of the test signal by switching it from transmission mode to test mode, and the transmission device itself is used as the receiver of the reflected signal, as well as to an optical device and to an optical transmission and reception device therefore.
Method for the reflectometric testing of an optical transmission line, in which a test signal is fed into the transmission line from the direction of an optical transmission device and the reflected signal is analysed, wherein the transmission device provided for transmitting the useful signal is also used as the transmitter of the test signal by switching it from transmission mode to test mode, and in that the transmission device itself is used as the receiver of the reflected signal.
Optical device for the reflectometric testing of an optical transmission line, having transmission means for feeding a test signal into the transmission line from the direction of the optical device, and having reception means for analysing the signal reflected back to the optical transmission and reception device, wherein the transmission means is the transmission device provided for transmitting the useful signal, and in that the reception means is the transmission device itself.
