Abstract
In a tool for measuring optical power on a fiber optic cable link, optical conditioning means in conjunction with a splitter are used to achieve measurement consistency and repeatability. In accordance with preferred embodiments of the present invention, light conditioning means are provided by disposing the optical fiber cable in a position so as to achieve mode filtering. This may be accomplished either by disposing the optical fiber in a coil, as for example in a mandrel, or disposing the coil in a series of serpentine or zig-zag paths.
