Modular kit of a device for monitoring the spectral offset of two channels in networks with optical wave multiplexes
Original language description
Disadvantages of general solutions are solved by a modular kit of a device for monitoring the spectral offset of two channels with different wavelengths allowing to measure changes of the times the signals travel in the transmission system, for example temperature-induced changes, in networks with optical wave multiplexes according to the presented solution. The kit contains the first and the second directional couplers, which are connected via an optical coupling element and the first optical filter with the first photodetector. The first photodetector is interconnected with the control unit equipped with wired and/or wireless communication interface and powered by the power supply module. The principle of the new solution is that the output of the first optical filter is connected to the input of the first photodetector via the second optical filter, while the second output of the second optical filter is connected to the input of the second photodetector. The output of the second photodetector is connected to the control unit. The third directional coupler, oriented identically with the first directional coupler, is connected between the output of the first directional coupler and the first input of the coupling element. The split branch of the third directional coupler is connected to the input of the third photodetector, the output of which is connected to the control unit. Simultaneously, the fourth directional coupler, oriented identically with the second directional coupler, is connected between the output of the second directional coupler and the second input of the coupling element. The split branch of the fourth directional coupler is connected to the input of the fourth photodetector, the output of which is connected to the control unit. Patent užívaný jen vlastníkem.
