Abstract
A light waveguide signal detector enables testing for the transmission of a signal in a light waveguide without disturbing the transmission of the signal. The light waveguide signal detector comprises a base part having a pressure trough lined with an optically transparent material, at least one light receiver being arranged under the elastic material, a pressure part for deflecting the light waveguide to obtain an emergence of a light signal therefrom and a light covering for protecting against stray light surrounding a portion of the pressure part which engages the optical fiber.
Claims14
A light waveguide signal detector comprising a base part having a pressure trough lined with an optically transparent, elastic material for receiving a light waveguide fiber to be tested;
- at least one light receiver being arranged in the base part under the transparent elastic material;
- a pressure part fitting into the pressure trough to hold the fiber in a curved path on the transparent elastic material, said pressure part being rounded on at least one side;
- and Unitary means having an opaque, elastic surface engaging said fiber and conformable to said pressure trough for simultaneously shielding a portion of the fiber in the curved path from external light and for elastically pressing said portion of the fiber in said curved path against said transparent elastic material.
