In the optical communication network for multiplex operation, an optical waveguide (LW1) emerging from a distribution point (VT) is in each case fed to a branching point (VZ), where the signals are divided up by means of a directional coupler (RK1) into two sub-signals. A second optical waveguide (LW2), which is connected to the second input (E2) of the directional coupler (RK), is also laid between the distribution point (VT) and the branching point (VZ). �<IMAGE>� |
