Launch fiber box
Pour la caractérisation étendue des câbles à fibres optiques
In optical technology, OTDR measuring devices are used in many applications. They enable extensive characterization of existing fiber optic cabling networks. It is advantageous to use launch fiber to ensure precise measurements. When measuring bidirectional backscattering with launch fiber, the attenuation values of the first and the last connections can be accurately determined.
Manufacturers of measuring devices recommend different lengths for launch fiber in order to avoid so-called “ghost reflections“. The launch fiber box is also subject to surveillance of the measuring method and should therefore regularly be revised according to the OTDR-measuring devices. Good measurement results strongly depend on the condition and the quality of the measuring equipment
