Abstract

An optical device assembly includes an optical device. The optical device has an optical fiber led from the device with an anti-kink protector, and also a transmitting and/or receiving module having such an optical device. The anti-kink protector is made of a material and/or the anti-kink protector is sheathed with a material that is electrically conductive or highly absorbent to electromagnetic waves. The transmitting and/or receiving module is constructed in such a way that the anti-kink protector is disposed in the area of an opening of the module housing and at the same time is coupled electrically to the module housing. The electrical coupling of the electrically conductive anti-kink protector to the module housing results in a considerable reduction in the interference radiation that emerges.
