Patent ID: 7197223

Claim:
A glass fiber monitoring module, comprising a mounting plate, couplings for receiving plugs of incoming and outgoing glass fibers; at least one coupler module being arranged on the mounting plate; couplers being arranged in the coupler module and each coupler being used to split signals of one incoming glass fiber between at least two outgoing glass fibers at a predeterminable ratio, one of the two outgoing glass fiber transmitting a useful signal and the other glass fiber transmitting a test signal, wherein the glass fibers carrying the test signals are combined in the coupler module to form one multifiber cable; a splitting element being arranged at one end of the multifiber cable 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 outgoing glass fibers transmitting a test signal; and plugs being arranged at remote ends of said monofiber cables.
