摘要：
In order to automatically recognize an overheating of an optical waveguide, a coupling device (16) for an optical waveguide (12, 8) comprises a optical waveguide connection (26) for a first optical waveguide (28). The coupling device (16) according to the invention comprises an optical filter (20) arranged in the beam path between a laser light source (11) and the optical waveguide connection (26) which reflects light of a first wavelength range (22) or a first polarization direction and transmits light of a second wavelength range (24) or a second polarization direction.
