ABSTRACT:
A mode filter for reducing a dynamic range of a write optical fiber bus which utilizes taps which initially inject optical signals into an optical fiber which have intensities skewed towards higher order modes rather than lower order modes as compared to equilibrium for the fiber functions to preferentially attenuate outermost modes rather than lowermost modes in the fiber so as to reduce a required dynamic range for an optical receiver.
