Abstract

The invention relates to a glass fiber monitoring module comprising a mounting plate, couplings for receiving plugs of incoming and outgoing glass fibers and at least one coupler module being arranged on the mounting plate, couplers being arranged in the coupler module and being used to split the signals of one incoming glass fiber between at least two outgoing glass fibers at a predeterminable ratio, one outgoing glass fiber transmitting a useful signal and the other glass fiber transmitting a test signal, the glass fibers carrying the test signals being combined in the coupler module to form one multifiber cable, a splitting element being arranged at that end of the multifiber cable which is remote from the coupler module and being used to split the multifiber cable into a number of monofiber cables which corresponds to the number of fibers, plugs being arranged at the ends of said monofiber cables.
