Abstract
In a method and a device for extracting signals out of a glass fiber without any detectable interference occurring, in particular without the signals propagating through the glass fiber experiencing any transmission loss, light that emerges laterally from the glass fiber due to scattering (Rayleigh scattering) processes, which are in existence anyway, is directed at a photodetector. In the process, the emerging light can be directed by focussing elements at the photodetector or at the input face of another glass fiber. In addition, the emerging light can be directed both directly as well as via at least one reflector at the photodetector.
