Optical fiber reflectance
WebHome Products Fiber Optics Reflection Probes To obtain spectral information of diffuse or specular materials, reflection probes are used. The light from a light source is sent through six illumination fibres to the sample and the reflection is measured by a 7th fibre in the centre of the reflection probe tip. WebThe optical return loss at the fiber interface is defined as. Return loss = -10 Log R. Return loss is only the amount of optical power reflected and does not include power that is transmitted, scattered or absorbed inside the fiber. Return loss and reflectance are important for fiber optic patch chords and connectors.
