ABSTRACT:
A light waveguide coupling device which is inserted at regular intervals along the light wave transmission link with each coupling device for each direction of transmission having a channel having a transducer module for converting optical signals into electrical signals, a regenerating amplifier to amplify the electrical signals and a transducer module for converting electrical signals back into optical signals for further transmission characterized by at least one external electrical connection terminal for each channel so that a remote control element can be connected into the waveguide system at the coupling device.
