Abstract
Techniques for monitoring optical power, dispersion and mode distribution in high speed multimode fiber are described. According to one aspect of the present invention, a multimode optical tap filter is described. In one aspect of the present invention, an optical tap filter is a dispersionless optical tap filter in bi-directional multimode fiber optic link. The optical tap filter includes at least two parts optically engaged with a broadband thin film filter and taps out a monitoring signal from a communication signal according to a ratio set by the broadband thin film filter.
