ABSTRACT:
An apparatus for coupling light into and out of optical waveguides to determine the amount of splicing attenuation at a splicing location between a first and second waveguide, characterized by a device for coupling light into the first waveguide and a device for coupling light out of the second waveguide. The device for coupling light into the first waveguide includes an arrangement for holding a portion of the first waveguide in a curved path to form a coupling region, a source of light and an additional optical waveguide for conducting light from the source to the coupling region. The output coupling device includes an arrangement for holding the second waveguide in a curved path, a photodetector for receiving light uncoupled from the second waveguide and an arrangement for measuring the intensity of the light received by the photodetector.
