The Ferrule end-face geometry characteristics are key factors to the quality of patch-cords interconnections. While interferometry measurement tools can measure some of these characteristics (Radius of polishing, Apex-offset, Fiber height, ...), they cannot measure the eccentricity of the fiber core with respect to the ferrule outer envelope. Fiber-core eccentricity can have various origins such as fiber cladding to core eccentricity, ferrule envelope to bore eccentricity and unmatched fiber diameter to ferrule bore diameter.

The result of eccentricity is a loss in optical power at interconnections and therefore a loss in performances.

With this module, KONCENTRIK-V2 measures the eccentricity of the fiber core with respect to the ferrule outer envelope of a connector with a 0.15µm precision. It also measures the position of the core with respect to the connector key with a few degrees of precision. Applications Production of Reference and Master patchcords. Tuning of connectors so as to reduce the random mating insertion loss of fibre optic assemblies.
