Latest Patents

Kevin W Johnston holds a patent for the "Dynamic Bendloss Measuring Device." This device allows for the easy and repeatable determination of the bend sensitivity of a single-mode optical fiber. It achieves this by subjecting the fiber to dynamically changing bend angles under varying degrees of tension and bend diameters. The device utilizes a swing arm capable of sweeping an arc that subtends a range of angles at any given bend diameter and fiber tension. It calculates the bendloss from the light attenuation at each degree of the range. The varying bend diameters are provided by pins of diverse diameters that can be inserted into an adjustably-sized aperture. The variation in the applied tension can be adjusted by changing the input current setting in the tension assembly. With each new pin and tension setting, the swing arm sweeps through the pre-selected range of bend angles, resulting in varying degrees of light attenuation.
