摘要
In order to locate faults in an optical transmission system, the optical waveguide in the forward transmission path of a repeater is coupled by a beam splitter to an optical waveguide loop at the output of an amplifier. The dividing ratio of the beam splitter is based on the sensitivity of the amplifier in the return transmission path of the repeater. In the return direction the optical waveguide loop is connectable instead of the optical waveguide of the return transmission path.
